Hydrocracking of hydrocarbons with a catalyst comprising an alumina- silica support, a group VIII metallic component, a group VI-B metallic component and a fluoride

摘要

Hydrocarbons are converted with a catalyst comprising an alumina- silica support, a Group VIII metallic component, a Group VI-B metallic component and a fluoride. Key feature of the process involves the preparation of the catalyst by initially impregnating the alumina- silica support with the Group VI-B and the Group VIII metallic components and by subsequently impregnating the previously impregnated composite with fluoride.
