Abstract: MULTIPLE CATALYST SYSTEM FOR HYDRODENITROGENATION OF HIGH NITROGEN FEEDS Hydrodenitrogenation of high nitrogen content hydrocarbon feeds comprises contacting the feed with hydrogen under hydrodenitrogenation conditions in the presence of a multiple catalyst system comprising an initial catalyst of apparent higher order reaction kinetics and lower rate constant for hydrodenitrogenation followed by at least one subsequent catalyst of apparent lower order reaction kinetics and higher rate constant for hydrodenitrogenation.

Abstract: CATALYST AND PROCESS FOR THE HYDROTREATING OF NITROGEN-CONTAINING FEEDS There are disclosed a catalyst and a process for the hydrodenitrogenation of a hydrocarbon stream containing a substantial amount of nitrogen compounds, such as whole shale oil. The catalyst comprises a hydrogenation component comprising chromium, molybdenum, and at least one Group VIII metal deposed upon a porous alumina-silica support, the silica of said support being present in an amount within the range of about 10 wt% to about 50 wt%, based upon the weight of said support. The process comprises contacting the hydrocarbon stream under hydrodenitrogenation conditions and in the presence of hydrogen with the aforesaid catalyst.

Abstract: There are disclosed a novel catalyst and a process employing that catalyst. The catalyst comprises a hydrogenation component comprising chromium, molybdenum, and at least one metal of Group VIII, a crystalline molecular sieve zeolite having pore diameters of at least 5 A (0.5 nm) and containing exchangeable cations, and a porous refractory inorganic oxide. Faujasite-type crystalline alluminosilicates, mordenite-type crystalline aluminosilicates, ZSM-type crystalline aluminosilicates, and AMS crystalline metallosilicates are suitable zeolites. The process comprises contacting a hydrocarbon stream containing a substantial amount of nitrogen under hydrotreating (hydrodenitrogenation and hydrocracking) conditions and in the presence of hydrogen with the aforesaid catalyst.
