Abstract
An aromatics/naphthalene rich stream obtained by processing heavy gas oil derived from tar sands and cycle oils derived from cracking heavy gas oil may optionally be blended and subjected to a hydrogenation process and a ring opening reaction typically in the presence of a zeolite, alumina, or silica alumina based catalyst which may contain noble metals and or copper or molybdenum to produce paraffinic feedstocks for further chemical processing.
