Abstract
Abstract A method for preparing a hydrocarbon conversion catalyst by providing a composite composed of alumina having associated therewith a Group VIB or VIII metal or compound and contacting the composite with an activator system comprising hydrogen and an organic fluoride compound having from two to 16 carbon atoms. The catalysts so prepared are useful in such hydrocarbon conversion processes as isomerization, hydrocracking, reforming, alkylation, disproportionation, polymerization and hydrogenation.
