METHOD FOR DESULFURIZING A HYDROCARBON FEEDSTOCK
A method of making a hydrodesulfurization catalyst having nickel and molybdenum sulfides deposited on a support material containing mesoporous silica that is optionally modified with zirconium. The method of making the hydrodesulfurization catalyst involves a single-step calcination and reduction procedure. The utilization of the hydrodesulfurization catalyst in treating a hydrocarbon feedstock containing sulfur compounds (e.g. dibenzothiophene, 4,6-dimethyldibenzothiophene) to produce a desulfurized hydrocarbon stream is also provided.
SELECTIVE HYDROGENATION CATALYST OBTAINED FROM MOLTEN SALTS AND AN ORGANIC ADDITIVE
A selective hydrogenation catalyst that can be obtained by the process comprising at least the following steps: a) the alumina support is brought into contact with at least one organic additive; b) the alumina support is brought into contact with at least one nickel metal salt, the melting point of said metal salt of which is between 20° C. and 150° C.; c) the solid mixture obtained on conclusion of steps a) and b) is heated with stirring; d) the catalyst precursor on conclusion of step c) is dried; e) a step of heat treatment of the dried catalyst precursor obtained on conclusion of step d) is carried out.
SELECTIVE PROCESS AND CATALYSTS FOR THE PRODUCTION OF RENEWABLE FUELS AND DISTILLATES OF HIGH MOLECULAR WEIGHT
The present invention relates to a process for the conversion of plant oils, animal fats, waste food oils and carboxylic acids into renewable liquid fuels, such as bio-naphtha, bioQAV and renewable diesel, for use in combination with fossil fuels. The process is composed of two steps: hydrotreatment and hydrocracking. The effluent from the hydrotreatment step contains aromatics, olefins and compounds resulting from the polymerization of esters and acids. This is due to the use of partially reduced catalysts without the injection of a sulfiding agent and allows for the production of bioQAV of suitable quality for use in combination with fossil kerosene. Concurrently, the process generates, in addition to products in the distillation range of naphtha, kerosene and diesel, high molecular weight linear paraffins (up to 40 carbon atoms).
METHOD FOR OBTAINING A SUPPORT FOR HYDROFINING CATALYSTS, SUPPORT FOR HYDROFINING CATALYSTS, HYDROFINING CATALYSTS, PROCESS FOR OBTAINING HYDROFINING CATALYSTS, AND USE OF SUPPORT IN HYDROFINING CATALYSTS
The present invention addresses to obtaining a support of hydrorefining catalysts by an innovative preparation route that reduces the problem of loss (or leaching) of boron over the operating time of industrial units. As the presence of boron in catalysts contributes to increased activity (hydrogenating and acidic) and stability for the hydrorefining reactions (hydrotreating and hydrocracking), its maintenance in the catalyst guarantees the preservation of the properties in operation, throughout the entire cycle of campaign of industrial units.
