摘要： The present invention relates to a catalyst composition and a process for preparing thereof, wherein the catalyst composition is specifically active for hydro-conversion of LCO involving mainly the partial ring opening of multi-ring aromatics leading to the production of petrochemical feedstock. The catalyst composition comprises of a carrier comprising ultra-stable Y zeolite and binder alumina, group VIB and VIIIB metal species, and organic additives. The carrier is impregnated with metal solution to form active sites of WS2 slabs of dimensions in the range of 35-45 Å.

摘要： A process for preparation of catalyst to produce ultra-low sulfur diesel (ULSD) from high refractory sulfur feedstock. The catalyst composition comprises a modified alumina carrier, impregnated by metal of group VIB is in the range of 15-25% and metal of group VIIIB is in the range of 1-5% as oxides. The catalyst prepared in the present invention produces highly dispersed MoS2 active sites on the modified carrier. The catalyst produces ultra low sulfur diesel (ULSD) along with improved cetane, density reduction and endpoint reduction.
