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.
Abstract:
There is provided a process for the reforming of a petroleum hydrocarbon stream, which process comprises contacting said hydrocarbon stream in a reforming zone under suitable reforming conditions and in the presence of hydrogen with a catalyst comprising a component having hydrogenation-dehydrogenation activity and dehydrocyclization activity, a suitable support, and as a promoter a small amount of technetium. The support may comprise alumina and the component having hydrogenationdehydrogenation activity and dehydrocyclization activity may be a member selected from the group consisting of one or more metals of Group VIA, compounds of one or more metals of Group VIA, and combinations thereof. The preferred Group VIA metal is chromium. The catalyst may comprise also a second member selected from the group consisting of an oxide of an alkali metal, an oxide of alkaline earth metal, and mixtures thereof.
