Abstract
Abstract A method for preparing a hydrocarbon conversion catalyst by providing a composite composed of alumina having associated therewith a Group VIB, VIIB or VIII metal or compound and contacting the composite with an activator system comprising carbon monoxide and sulfuryl fluoride or thionyl fluoride. The catalysts so prepared are useful in such hydrocarbon conversion processes as isomerization, hydrocracking, reforming, alkylation, disproportionation, polymerization and hydrogenation.
