Abstract
A catalyst is provided for hydrodeoxygenation and hydroisomerization of paraffins having higher activity. The catalyst contains a molecular sieve, such as SAPO-11, a metal component such as platinum and/or palladium or nickel tungsten sulfide or nickel molybdenum sulfide and a binder such as gamma alumina. The catalyst exhibits a high proportion of weak acid sites and a relatively equal distribution of the metal component on the molecular sieve and the binder.
Claims20
A catalytically active material comprising a metal component, and comprising as a support at least a molecular sieve, a metal oxide, and a carbon material, wherein a portion of said metal component is dispersed on said molecular sieve and a second portion of said metal component is dispersed on said metal oxide, and wherein carbon as carbon material is in the support, excluding the supported active metal components.
A process for dewaxing a hydrocarbon or a hydrocarbon mixture involving contacting said hydrocarbon or hydrocarbon mixture with a catalytically active material comprising a metal component, and comprising as a support at least a molecular sieve, a metal oxide, and a carbon material, wherein a portion of said metal component is dispersed on said molecular sieve and a second portion of said metal component is dispersed on said metal oxide, and wherein carbon as carbon material is in the support, excluding the supported active metal components in the presence of hydrogen under dewaxing conditions.
A method for making a catalyst comprising extruding a molecular sieve with a pseudo-boehmite to produce an extrudate that is calcined to gamma alumina and then impregnating said gamma alumina and molecular sieve with a metal component to provide an impregnated extrudate, wherein 40-60% of said metal component was dispersed on the molecular sieve portion and about 40-60% of said metal component was dispersed on the gamma alumina, and then oxidizing the impregnated extrudate.
