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 about 40-60% of said metal component is dispersed on said molecular sieve and about 40-60% of said metal component is dispersed on said metal oxide, and wherein 25 wppm-1000 wppm 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 about 40-60% of said metal component is dispersed on said molecular sieve and about 40-60% of said metal component is dispersed on said metal oxide, and wherein 25 wppm-1000 wppm carbon as carbon material is in the support, excluding the supported active metal components in the presence of hydrogen under dewaxing conditions.
