This proposal aims at a compact version of a gasifier by integrating the fluidized bed steam gasification of biomass and the hot gas cleaning and conditioning system into one reactor vessel. Such arrangement will guarantee the conversion of tar, elimination of trace elements and an efficient abatement of the particulate, delivering high purity syngas, suitable to assure a substantial share of power generation even in small- to medium-scale (few MWth) CHP and power plants, and to increase the overall economic revenue, in line with the FP7 energy directives. It is expected that this innovation will provide a concrete contribution to the target fixed in the work programme of reducing the cost of electricity obtained by means of advanced gasification systems below 0.04 /kWh in 2020. The strategy of the work plan is designed to: (i) carry out systematic investigations into the development of catalytic and sorbent materials and verify their effectiveness to improve gas quality at real gasification conditions with tests at bench- to pilot-scale (up to 100kWth); (ii) evaluate the purity of syngas against existing cleaning and conditioning systems, by means of a proof of concept in the Gssing gasification plant, and the compatibility towards advanced power generation systems, by means of electricity production tests with a SOFC unit; (iii) assess technical feasibility of process simplification and intensification actions by means of design and operation of an integrated gasification and hot gas cleaning and conditioning fluidized bed prototype reactor (1 MWth), at a significant scale to provide sufficient and reliable information for industrial applications. This ambitious project relates well to the complementary expertises of applicants. Consortium also includes the stakeholders relevant to assure the necessary impact for dissemination and exploitation of the results, and to promote in the medium term industrial applications for the commercialisation of the innovation.

Through development and scale up activities on materials and reactors for the integration of advanced biomass steam gasification and syngas purification processes, UNIfHY aims to obtain continuous pure hydrogen production from biomass, increase well-to-tank efficiency and contribute to a sustainable energy portfolio, exploiting results achieved in past R&D EU projects on hot gas catalytic conditioning. The project is based on the utilization of plant components of proven performance and reliability and well established processes (UNIQUE coupled gasification and gas conditioning technology, Water-Gas Shift, WGS, system and Pressure Swing Adsorption, PSA, system), thus targeting up to 20 years plant durability with availability>95%. The project benefits from the already existing laboratories and UNIQUE gasifiers in order to maximize results (technology development at process-, system- and industrial-scale) with minimum risk and budget requirement (laboratories, pilot and industrial gasifier already available). New materials for atmospheric pressure WGS are realized and utilized to develop reactors, integrated with a tailored PSA in a portable purification unit, connected downstream small-to-medium scale (up to 1 MWth) UNIQUE gasifiers in order to yield pure hydrogen. The result will be two UNIfHY prototype units for continuous production of hydrogen (up to 500 kg/day). Thanks to the high level of thermal integration and to the reuse of purge gas in the process, conversion efficiency in hydrogen higher than 70% is expected. Finally, the gas conditioning system cost becomes 30% as that of a standard free-standing conditioning system, due to remarkable plant integration: reforming of both tar and methane and particulates abatement is carried out directly in the freeboard of the biomass gasifier, providing investment cost savings greater than 50%, a simplified plant layout with reduction of space and components up to 50% and a hydrogen production cost not exceeding 4/kg.

Enhancing biomass utilization without risking its sustainability is a European energy priority, and can be linked to targets for curbing greenhouse gas emissions by 20% by 2020 and 50% by 2050: enhanced energy security and integration with other industrial sectors, such as agriculture, also play a role. Improved use of biofuels and products in advanced biomass conversion units and biorefineries are seen as a key element in achieving this goal. In recent years leading industrial nations have established facilities in which their researchers have addressed the challenges associated with the production of biofuels and the establishment of bio-refineries. There remains fragmentation in terms of access to high-level experimental equipment necessary for achieving significant advances in this field. The BRISK initiative will integrate networking activities to foster a culture of co-operation between the participants in the project, and the scientific communities benefiting from access to the research infrastructures, with the pursuit of joint research activities, and facilitate transnational access by researchers to one or more infrastructures among those operated by participants in a coordinated way so as to improve the overall services available to the research communities with interests in these fields.

A bench-scale fluidized-bed biomass gasification plant, operating at atmospheric pressure and temperature within the range 800-820 °C, has been used to test an innovative gas cleaning device: a catalytic filter candle fitted into the bed freeboard. This housing of the gas conditioning system within the gasifier itself results in a very compact unit and greatly reduced thermal losses. Long term (22 h) tests were performed on the gasifier both with and without the catalytic candle filter, under otherwise identical conditions. Analysis of the product gas for the two cases showed the catalytic filtration to give rise to notable improvements in both gas quality and gas yield: an increase in hydrogen yield of 130% and an overall increase in gas yield of 69% - with corresponding decreases in methane and tar content of 20% and 79%, respectively. HPLC/UV analysis was used to characterize the tar compounds. © 2010 Elsevier Ltd. All rights reserved.

Gasification is considered as a key technology for the use of biomass. In order to promote this technology in the future, advanced, cost-effective, and highly efficient gasification processes and systems are required. This paper provides a detailed review on new concepts in biomass gasification. Concepts for process integration and combination aim to enable higher process efficiencies, better gas quality and purity, and lower investment costs. The recently developed UNIQUE gasifier which integrates gasification, gas cleaning and conditioning in one reactor unit is an example for a promising process integration. Other interesting concepts combine pyrolysis and gasification or gasification and combustion in single controlled stages. An approach to improve the economic viability and sustainability of the utilization of biomass via gasification is the combined production of more than one product. Polygeneration strategies for the production of multiple energy products from biomass gasification syngas offer high efficiency and flexibility. © 2014 Elsevier Ltd. All rights reserved.

During the CHRISGAS project, various experimental campaigns were performed with the aim to study the hot gas filtration process during steam-O2 biomass gasification at Delft University of Technology. The test-rig consists of a 100 kW thermal atmospheric circulating fluidized-bed gasifier and a high temperature filter unit which contains 3 rigid ceramic candles with an outer diameter of 60 mm, 10 mm wall thickness and a length of 1520 mm. This paper gives an overview of tests performed with different fuels (A-wood, B-wood, miscanthus) and with sand and magnesite used as bed materials. Dia-Schumalith11Dia-Schumalith is a trademark of Pall Corporation. candles were operated in the temperature range between 600 °C and 800 °C for more than 50 h. The filtration performance was studied through continuous observation of the increasing differential pressure while the filter cake formed on the surface of the candles. Gas face velocities ranged between 3 cm s-1 and 5 cm s-1. Stable filtration was achieved during some tests. Dust cake analysis indicated formation of calcium phosphates and silicates and potassium silicates. © 2011 Elsevier Ltd.

Two experimental campaigns were performed with the aim to study the effect of two different bed materials, magnesite and olivine during steam-O2 biomass gasification. The test-rig consists of a 100 kWth atmospheric circulating fluidized-bed gasifier and a high temperature filter unit which contains 3 rigid ceramic candles with an outer diameter of 60 mm, 10 mm wall thickness and a length of 1520 mm. Tests were performed with different fuels (A-wood, B-wood, miscanthus and straw). Two types of filter elements were used, Dia-Schumalith1 (DS3) and Dia-Schumalith1 N (DSN1), which operated at 800°C for 58 h and 50 h, respectively. The filtration performance was studied through continuous observation of the increasing pressure drop during the build-up of the dust cake. Gas face velocities ranged between 2.5 and 5 cm s-1. DSN1 elements showed longer steady filtration compared to DS3 candles with filtration efficiencies equal to 100%. Formation of calcium and potassium silicates resulted from filter cake analyses. The filtration process influenced gas and tar composition of the incoming gas flow. Hydrogen content increased about 10% (dry basis) and the heavier tar compounds appeared to be broken into lighter chains, such as naphthalene whose concentration increased. © 2011 Elsevier Ltd.

This paper provides a detailed survey on hot gas filtration. Fundamental aspects of filtration at higher temperatures are described first, including the influence of the temperature on dust properties and filtration behaviour. The main focus is on the review of hot gas filter media as well as hot gas filter systems. Moreover, applications of hot gas filtration are presented and discussed in detail, for example advanced coal gasification as well as biomass gasification and pyrolysis, incineration of low-level contaminated radioactive waste from nuclear power generation, waste incineration, fluid catalytic cracking in oil refineries and other processes. By using hot gas filters, downstream equipment, such as heat exchangers, catalyst units, turbines and scrubbers, are protected from erosion and fouling, processes can be intensified or simplified as well as blocking by condensation or desublimation can be prevented. Energy efficiency, process intensification, PM 10 and PM 2.5 emission values, water shortage and water quality as well as overall process costs are topics which raise an increasing interest in hot gas filtration. © 2010 Elsevier Ltd.
