Abstract: Process for producing a light gasoline having a sulfur content of less than 10 ppm by weight, with respect to the total weight of the light gasoline, starting from a gasoline containing sulfur compounds, olefins and diolefins, which process includes a) a stage of selective hydrogenation to hydrogenate the diolefins and a reaction for increasing the molecular weight of a part of the sulfur compounds; b) a stage separating the effluent obtained from stage a) into a gaseous fraction, a light gasoline cut and a heavy gasoline cut, stage b) being carried out in a fractionation column containing n plates, n being an integer of 20 or more, the first plate being the reboiler and the plate “n” being the condenser, wherein the light gasoline cut is withdrawn from the fractionation column at the plate “n-i”, with i being 1 to 10.

Abstract: Carbon nanofiber doped alumina (Al-CNF) supported MoCo catalysts in hydrodesulfurization (HDS), and/or boron doping, e.g., up to 5 wt % of total catalyst weight, can improve catalytic efficiency. Al-CNF-supported MoCo catalysts, (Al-CNF-MoCo), can reduce the sulfur concentration in fuel, esp. liquid fuel, to below the required limit in a 6 h reaction time. Thus, Al-CNF-MoCo has a higher catalytic activity than Al—MoCo, which may be explained by higher mesoporous surface area and better dispersion of MoCo metals on the AlCNF support relative to alumina support. The BET surface area of Al—MoCo may be 75% less than Al-CNF-MoCo, e.g., 166 vs. 200 m2/g. SEM images indicate that the catalyst nanoparticles can be evenly distributed on the surface of the CNF. The surface area of the AlMoCoB5% may be 206 m2/g, which is higher than AlMoCoB0% and AlMoCoB2%, and AlMoCoB5% has the highest HDS activity, removing more than 98% sulfur and below allowed levels.

Abstract: The specification discloses a highly macroporous catalyst for hydroprocessing and hydroconversion of heavy hydrocarbon feedstocks. The high macroporosity catalyst incudes an inorganic oxide, molybdenum, and nickel components. It has a pore structure such that at least 18% of its total pore volume is in pores of a diameter greater than 5,000 angstroms and at least 25% of its total pore volume is in pores of a diameter greater than 1,000 angstroms. Preferably, the pore structure is bimodal. The catalyst is made by co-mulling the catalytic components with a high molecular weight polyacrylamide followed by forming the co-mulled mixture into a particle or an extrudate. The particle or extrudate is dried and calcined under controlled calcination temperature conditions to yield a calcined particle or extrudate of the high macroporosity catalyst composition.

Abstract: A system and method for renewable diesel synthesis utilizes a triglyceride feedstock derived from biological sources. The first step involves hydrolysis of the triglycerides into an intermediate feedstock comprising a mixture of free fatty acids and glycerol (separated from the FFA by decantation and then distilled). The FFA is then further processed in a distillation step to produce a stream free of catalyst poisons and utilized as feedstock for hydrotreatment in a renewable diesel production process. By converting the initial triglyceride feedstock to an FFA feedstock, the need to hydrotreat at typical high temperature that promote the decarboxylation reaction is obviated, thereby reducing the production of CO2, generating a significantly higher proportion of saturated, long chain C14, C16 or C18 hydrocarbons (as opposed to short-chain carbons such as propane), and the more valuable glycerol product is secured.
