Abstract
A process for hydrocracking heavy hydrocarbon feeds using a catalyst composition containing a hydrogenation/dehydrogenation component, such as a noble metal, and an acidic solid component including a Group IVB metal oxide modified with an oxyanion of a Group VIB metal. The hydrocracking product has high isoparaffin to normal paraffin ratios and with minimal ethane and methane byproducts at high conversions. The hydrocracking step is useful in processes for producing high quality lubricating oil basestocks, along with naphtha and distillate products.
