The exergy analysis of a compression ignition (CI) engine for quantification of fuel to available energy could be the most effective tool to determine the fuel efficiency and effectiveness. During this investigation a few diesel-biodiesel blends were investigated for performance analysis in diesel engines under different load conditions using an exergy-based study. From this focused investigation, it was ascertained that biodiesel blends of B10 and B20 for apricot, argemone, karanja, nahar, and neem showed relatively better performance than petrodiesel at 80% load. As much as 30% of available input energy was estimated for shaft operation. Also diesel showed higher destroyed availability, whereas all other blends showed 1-3% less than diesel, which is a significant finding of this work. Among all the diesel-biodiesel blends, Argemone mexicana (ARB20) was found to be the best both in terms of biodiesel production and performance parameters. Thus, biodiesel blend B20 was found equally efficient in terms of virtual available energy and could be effectively used as a substitute for petrodiesel without compromising the shaft efficiency. © 2016 American Society of Civil Engineers.

Overproduction of metabolites, high product yield and process economics are greatly influenced by the media composition used for growth and fermentation. The main purpose of this study is to enhance the ethanol production through statistical tool of response surface methodology (RSM) by optimizing media components for the growth and fermentation of thermotolerant isolates Kluyveromyces marxianus NIRE-K1 and NIRE-K3. Five different salts were used in the Face-centered Central Composite Design (FCCD), with the responses of biomass formation and ethanol production for growth and fermentation, respectively. Yeast extract and K2HPO4 were found to be the key media components for the growth and fermentation which is revealed from their interaction in both the yeast isolates. Further studies on batch fermentation kinetics using the optimized values of the medium composition for K. marxianus NIRE-K1 and NIRE-K3 resulted in final ethanol concentration of 17.73 (86.27% of theoretical ethanol yield) and 19.01 g l−1 (94.12% of theoretical ethanol yield), respectively. An increase in the ethanol yield and productivity by 11.36, 10.42% and 2.0, 2.7% was revealed in NIRE-K1 and NIRE-K3, respectively, as compared to our previous study. © 2017 Elsevier Ltd

A large share of the total conventional energy generation from fossil fuels gets consumed for cooling and heating applications to maintain the thermal comfort of the individuals. The different cooling equipments during the operation also generate the losses which in turn reduces the overall performance of the systems. The present study therefore is based on the review of various thermodynamic and economic parameters that can be controlled in cooling machine to optimize the performance as well as to check the economic feasibility of the system. The different advanced methodologies to analyze the performance of the system along with different energy storage strategies have also been analyzed in the study. The review study clearly stressed on the fact that renewable energy sources are the best suitable options to run cooling systems provided they are well integrated and managed according to the suitable operational parameters. The economic study however, strictly points that the installed system must be economically feasible in terms of deciding economic parameters like net present worth (NPW), discounted pay back (DPB), capital recovery factor (CRF), etc. Besides, the present study also reveals that the check on irreversibility helps in improving the economy of the system. © 2016 Elsevier Ltd

This study reports production of microbial oil from a yeast strain Trichosporon sp., (RW) isolated from decayed wood. Preliminary analysis based on fluorescence microscopy and spectroscopy of Nile red stained yeast cells showed accumulation of lipid globules. The potential of the yeast to produce lipids was evaluated on glucose, glycerol and acid hydrolysate of sugarcane bagasse, where Trichosporon sp. (RW) was found to accumulate 21.45 (59.6%), 18.41 (56%) and 10.25. g/l (40.5%) of the lipids after 120. h of fermentation at 30. °C. FAME analysis of lipids by GC-FID and NMR revealed oleic acid (18:1) as the major constituent, corresponding to 50.05, 46.48 and 54.66% of the accumulated lipids in glucose, glycerol and hydrolysate grown cultures, respectively. Other accumulated lipids included palmitic (16:0), linoleic (18:2) and stearic acids (18:0) in that order. The cetane number of the lipids ranged from 52.39 to 59.57 indicating suitability for biodiesel production. © 2017 Elsevier Ltd.

The progressive rise in energy crisis followed by green house gas (GHG) emissions is serving as the driving force for bioethanol production from renewable resources. Current bioethanol research focuses on lignocellulosic feedstocks as these are abundantly available, renewable, sustainable and exhibit no competition between the crops for food and fuel. However, the technologies in use have some drawbacks including incapability of pentose fermentation, reduced tolerance to products formed, costly processes, etc. Therefore, the present study was carried out with the objective of isolating hexose and pentose fermenting thermophilic/thermotolerant ethanologens with acceptable product yield. Two thermotolerant isolates, NIRE-K1 and NIRE-K3 were screened for fermenting both glucose and xylose and identified as Kluyveromyces marxianus NIRE-K1 and K. marxianus NIRE-K3. After optimization using Face-centered Central Composite Design (FCCD), the growth parameters like temperature and pH were found to be 45.17°C and 5.49, respectively for K. marxianus NIRE-K1 and 45.41°C and 5.24, respectively for K. marxianus NIRE-K3. Further, batch fermentations were carried out under optimized conditions, where K. marxianus NIRE-K3 was found to be superior over K. marxianus NIRE-K1. Ethanol yield (Yx/s), sugar to ethanol conversion rate (%), microbial biomass concentration (X) and volumetric product productivity (Qp) obtained by K. marxianus NIRE-K3 were found to be 9.3, 9.55, 14.63, and 31.94% higher than that of K. marxianus NIRE-K1, respectively. This study revealed the promising potential of both the screened thermotolerant isolates for bioethanol production. © 2015 Arora, Behera, Sharma and Kumar.

Abstract The progressive depletion of non-renewable energy sources worldwide, together with the fact that their overexploitation has resulted in environmental deterioration and public health problems, has led to consider alternative sources of energy. Lignocellulose-based bioethanol is a leading option among alternatives to petroleum-derived transportation fuels due to its potential sustainability. The production of ethanol through microbial fermentations has generated considerable research interests. Several thermophilic/thermotolerant ethanologenic species i.e. Clostridium thermocellum, C. thermohydrosulfuricum, C. thermosaccharolyticum, Caldicellulosiruptor sp., Thermotoga sp., Thermoanaerobium brockii, Thermoanaerobacter ethanolicus, T. thermo-hydrosulfuricus, T. mathranii, etc., have been isolated and identified as the potential lignocellulosic ethanol producers. Use of lignocellulolytic organisms alone at high temperatures could potentially reduce the cellulase requirement. Moreover, such cultures facilitate the ethanol production at high temperature and offer the possibility of in-situ ethanol recovery. However, more research on the metabolic pathways, regulation of end-product formation and construction of genetically engineered thermophilic/thermotolerant microorganisms with high tolerance to ethanol is required for optimal utilization of such microbes in industrial fermentations. Therefore, the present review has been focused on thermophilic/thermotolerant microbes for the production of ethanol, especially on their catabolic pathways, end-product formation and their future perspectives for industrial applications. © 2015 Elsevier Ltd.

Dry grinding behavior and powder characteristics of raw and parboiled Pusa 1121 basmati rice brokens were assessed. Grinding duration was found to be having the role in deciding the ultimate size of ground particles with the particle size distribution and confirmed its direct influence on the characteristics of pretreated parboiled rice. Grinding laws namely Kick's, Rittinger's and Bond's law were applied. The grinding constants (KK, KR, WI) for different laws reflected the dependency on grinding duration. Dry grinding of raw rice brokens produced higher fractionations on smaller sieve size in comparison with parboiled rice brokens in the identical grinder and grinding process. Dry grinding of raw and parboiled broken rice resulted in significant difference in powder characteristics. Consequently, the grinding time and powder characteristics of raw rice brokens are more viable in producing fine particulates than parboiled one. © 2016, Farm Machinery Industrial Research Corp.

Catalytic hydrocracking of high free fatty acid (FFA) containing Mesua ferrea L. and Jatropha curcas oil (triacylglycerol) was investigated using biomass derived heterogeneous catalysts viz. Musa balbisiana Colla underground stem (MBCUS) nanomaterial and biomass based thermal power plant fly ash (BBTPFS). Reactions were studied in a batch mode in a bench scale reactor at 400 °C under variable initial H2 pressure (1-75 bar) for 1-4 h using 1-5 wt.% catalysts loading. Our results confirm that the reaction network consisted of multiple pathways leading to a product mixture rich in hydrocarbons, non-polar oxygenates and organic acids commonly known as biocrude. Decarboxylation, hydrolysis, hydrocracking and thermocatalytic cracking appeared to be the dominating reactions subsequently leading to the production of hydrocarbon mixture of chain length C8-C19. The resultant biocrude was fractionated into four fractions within the boiling range 35-140 °C, 140-180 °C, 180-370 °C and 370-482 °C as per ASTM D2892 and ASTM D5236 specifications. Further, the recovery in each fraction was directly affected by biocrude quality which in-turn was dependent upon catalyst properties and reaction conditions. The reaction networks were also varied significantly with respect to reaction atmosphere and as well as for the two catalysts which directly affected the yield and quality of product (higher heating value, acidity index, liquid distillate recovery etc). To summarize, BBTPFS was found to be a more effective catalyst for acidity and heteroatom removal, and consequently, produced biocrude with lowest acidity and highest percentage (65%) of the product in the liquid hydrocarbon range. © 2015 Elsevier B.V.

ABSTRACT: The combustion and pyrolysis kinetics of three selected biomasses generated as co-products of the oil and biodiesel industry – namely soya husk (SH), jatropha husk (JH), and Mesua ferrea husk (MH) – using thermogravimetric and differential thermal analysis techniques have been reported. These biomasses were initially characterized for basic fuel property, proximate analysis, ultimate analysis, and fiber analysis. The activation energy calculated using three different kinetic equations, viz. Coats and Redfern, Differential, and Friedman methods for combustion, were found higher than that for pyrolysis for all biomasses at the maximum airflow rate (20ml/min). However, the kinetic parameters are not sufficient alone to explain the suitability of the biomass. © 2016 Taylor & Francis Group, LLC.

The evolutionary adaptation was carried out on the thermotolerant yeast Kluyveromyces marxianus NIRE-K1 at 45 C up to 60 batches to enhance its xylose utilization capability. The adapted strain showed higher specific growth rate and 3-fold xylose uptake rate and short lag phase as compared to the native strain. During aerobic growth adapted yeast showed 2.81-fold higher xylose utilization than that of native. In anaerobic batch fermentation, adapted yeast utilized about 91% of xylose in 72 h and produced 2.88 and 18.75 g l of ethanol and xylitol, respectively, which were 5.11 and 5.71-fold higher than that of native. Ethanol yield, xylitol yield and specific sugar consumption rate obtained by the adapted cells were found to be 1.57, 1.65 and 4.84-fold higher than that of native yeast, respectively. Aforesaid results suggested that the evolutionary adaptation will be a very effective strategy in the near future for economic lignocellulosic ethanol production.
