Hydrocarbon conversion catalytic composite

摘要

A catalytic composite, comprising a combination of a nickel component and a tungsten component with a silica-alumina carrier material wherein the atomic ratio of nickel to nickel plus tungsten is about 0.1 to about 0.3. The key feature of the subject composite is the criticality of the ratio of nickel to nickel plus tungsten. The principal utility of the subject composite is in the hydrocracking of hydrocarbons. A specific example of the catalyst disclosed is a combination of nickel and tungsten with a silica-alumina carrier material containing 50 wt.% alumina in amounts sufficient to result in the composite having an atomic ratio of nickel to nickel plus tungsten of 0.2.
