Process for the production of white oils from heavy alkylate by-product.

摘要

A white oil product is produced by hydrogenating a C15 to C50 hydrocarbon stream produced from an aromatic alkylation process. The hydrogenation occurs at hydrogenation conditions in the presence of a catalyst comprising a platinum group metal component and an optional alkali component on a refractory oxide catalyst support. The platinum group metal component is preferably surface preferably impregnated such that the platinum group metal is essentially all located within a 100 micron layer of the surface of the catalyst support.
