Abstract
There is provided a hydrocracking process using a catalyst comprising a hydrogenation/dehydrogenation component, such as a noble metal, and an acidic solid component comprising a Group IVB metal oxide modified with an oxyanion of a Group VIB metal. An example of this catalyst is zirconia, modified with tungstate and platinum. This catalyst is used to selectively hydrocrack naphtha range hydrocarbons to reduce the endpoint of reformulated gasolines.
