In last two decades, the business of refining catalyst has grown from regional to global level. Refinery product values are dependent on process catalysts of refined products, petrochemical products and chemicals alongwith other refinery operations. One of the major concerns in the refinery is to reduce the sulphur content to the required limit. Hydro-processing catalysts (HPC) are primarily consumed in the hydro-processing operation of crude oil fractions. Such crude oil fractions include kerosene, naphtha and diesel. As a common practice, hydro-processing of crude oil fractionsis carried out at an elevated temperature and pressure.Hydro-processing is required to remove pollutants such as sulphur, heavy metals and nitrogen from fuel oils. These catalysts also help in the catalytic hydrocracking process to crack larger hydrocarbon molecules into smaller sizes,to be used as fuel oils. Thus, hydro-processing catalysts enable conversion of heavy feedstock into lighter products for efficient processing. Hydro-processing catalysts market is the fastest growing refinery catalysts market segment in the world. In addition, hydro-processing catalysts supplement the process control and operational efficiency improvement activities. Therefore, it is expected that the hydro-processing catalyst market will dominate the global refinery catalyst market by 2020. The global hydro-processing catalysts market can be categorized on the basis of its product type as molybdenum oxides, cobalt oxides, nickel oxidesand tungsten oxides. These metal oxides are carried on a carrier or matrix of silica, alumina and silica/alumina. Further, global hydro-processing catalysts market can also be categorized on the basis of their applications such as creating cleaner fuels, ultra-low sulphur levels in diesel fuels (ULSD) and others. On the basis of technology, global hydro-processing catalysts market can be segmented as hydro-treating catalysts, hydrogenation catalysts, hydrocracking catalysts, isomerisation catalyst and reforming catalyst. Among these, hydro-treating catalysts are dominant segment at present,accounting for more than half of the global hydro-processing catalysts market. Refiners are more focusing to maximize residue feedstock yield through hydro-processing catalysts as petroleum product prices are rising globally. This is one of the key supply side drivers of the global hydro-processing catalysts market. Moreover, stringent environmental regulations and legislations are expanding, which, in turn, affects the heaviercrude processing and sulphur elimination process market.Enhanced refinery capacities coupled with the rising oil production are driving the growth of global hydro-processing catalysts market. Environmental fuel specifications regulations introduced by Europe, the U.S.and few Asia Pacific countries have been driving the global hydro-processing catalysts market.Further, developed countries have mandate to reduce sulphur content whereassulphur restrictions are implemented in the developing countries such as India, China and Mexico. As hydro-processing catalysts are advantageous to reduce sulphur content, these countries are likely to open up opportunities for hydro-processing catalysts market. Due to presence of giant oil and gas chemical manufacturers in the refinery catalyst market; the market competition is quite high. Expansion of production facilities in oil producing fields along with the strategic alliances are few of the major market strategies in the global hydro-processing catalysts market. Some of the major market participants of global hydro-processing catalysts market include HaldorTopsøe, W. R. Grace and Company, Albemarle Corporation, Axens, UOP- Honeywell International Inc., Chevron Corporation, Royal Dutch Shell plc, BASF SE, Criterion Catalysts & Technologies, Criterion catalysts & Technologies and others. Among these, BASF has increased its R&D efforts since it acquired Engelhard. Further, BASF SE has come up with new developments in the processing of residue to increase the quality of yield.W.R. Grace and Companyhas introduced new products inthe hydro-processing catalysts market in the past five years. Thus, it is clear that global hydro-processing catalysts market participants are focused to expand their business through innovative product launches with specific market application. These innovative products include catalyst to eliminate sulphur content upto mandate limits. The worldwide hydro-processing catalysts market stands ready to meet the challenges, where energy costs significantlyfluctuate. However,fluctuating raw material prices, price spike, price collapse along with the governments enact legislation for certain related products or technologies, the demand of hydro-processing catalyst market are expected to undergo fluctuation.

Refiners are processing more and more crudes derived from the extraction of oil from shale deposits. While these "Tight Oils" have revolutionized crude supplies in the United States, they are presenting Refiners with new challenges. These crudes produce hydrocracker feeds with significantly fewer contaminants than Oil Sands derived feeds or conventionally produced gas oils, but they are causing crude blending compatibility issues, furnace and heat exchanger fouling, yield selectivity changes, and product quality issues which the Refinery has to contend with. In this study, Criterion/Zeolyst examines the performance of several hydrocrackers that are processing feeds that have been generated from crude from the Eagle Ford basin. The impact on hydrocracker catalyst life cycles, yield selectivities, and product quality is discussed. Opportunities may now exist to use more diesel selective hydrocracking catalysts with cold flow improvement capabilities as Refiners contend with these very paraffinic feeds. We explore how the Refinery configuration will dictate how much of this Tight Oil derived feed can be processed in the hydrocracker or if maybe this feed should be processed in other conversion units.

Alon Big Springs Refinery, with Criterion Catalysts, has worked for over ten years to achieve an impressive track record of successes in their distillate hydrotreater, boosting diesel capacity and production by up to 20%, and greatly improving unit flexibility. With the current strong market for diesel, this gain has allowed them not only to track their product demands, but it has dramatically boosted profitability for their shareholders. The sustained collaboration between Alon and Criterion has been a crucial factor in the success of the whole refinery. In the early 2000's Criterion worked with Shell Global Solutions to find a cost-effective way to bring Alon's distillate hydrotreater unit to ULSD production. The low operating pressure, difficult feed, and limited hydrogen availability were serious challenges. The refinery chose to install new reactor vessels with reactor internals from Shell Global Solutions. The catalyst was Criterion's first-generation Cobalt-Moly ULSD product. In the years following their successful transition to ULSD production, Alon continued to work closely with Criterion. The challenge was to extend the catalyst life cycle and increase straight run diesel (SRD) and light cycle oil (LCO) cut-points for improved refinery economics. They needed to push the cycle from about nine months to at least 12 months in order to synchronize with the semi-regen reformer regenerations. Increasing demand for diesel was putting pressure on the refinery to raise cut-points of their straight-run and LCO to maximize diesel yields. In 2010, Alon loaded a first-generation CENTERA™ sandwich system which gave a large boost in activity and enabled significant gains towards increasing the unit's flexibility and profitability. In 2014 Alon implemented a revamp in their crude distillation unit. One of the main objectives of that revamp was to boost straight-run diesel yield which would increase available feed to the ULSD unit for higher diesel production. Again, the success of this project was crucial for the refinery to increase profitability in the face of shifting market demand. Criterion's second-generation CENTERA™ sandwich system with DC-2635 CoMo and DN-3636 NiMo has given the additional activity needed to process the additional difficult feed and, at the same time, maintain catalyst cycle flexibility, once again contributing to Alon's success.

Molybdenum disulfide nanoparticles supported on titania were synthesized from aqueous solutions containing Ti and Mo precursor salts by an insitu redox reaction. The synthesis involves a redox process between Ti3+ and MoS4 2-, which proceeds readily under mild conditions in aqueous solution. Catalysts were made in a single step, yielding amorphous catalysts with high Mo content, or in two steps to obtain MoS2 supported on well-defined TiO2 with lower Mo content. Catalysts obtained by single-step reductive coprecipitation were highly active in the hydrodesulfurization of dibenzothiophene, exceeding the activity of an alumina-supported Co-Mo reference. In contrast to alumina-supported catalysts, the addition of Co as promoter did not enhance the catalytic activity of MoS2/TiO2 to the same extent (+30%) as for alumina-supported Co-Mo catalysts. Instead, a change in selectivity towards hydrogenolysis products at the expense of hydrogenation products was observed. It is suggested that Ti may act as a promoter for MoS2 in hydrogenation reactions. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Hydrotreating removes sulfur, nitrogen, olefins, aromatics, and other contaminants from distilled crude oil fractions and intermediate process streams. Hydrocracking converts heavy oil fractions into lighter, more valuable products. Both processes share many common features, so they often are discussed together as "hydroprocessing". Most hydroprocessing units employ specialized catalysts and consume hydrogen. Most hydroprocessing catalysts are comprised of active metals and promoters on solid supports. Hydroprocessing configurations can include fixed-bed reactors, ebullating bed reactors, or slurry-phase reactors, each of which requires a different kind of catalysts or a non-catalytic additive. This is an abstract of a paper presented at the 2012 AIChE Spring National Meeting and 8th Global Congress on Process Safety (Houston, TX 4/1-5/2012).
