Abstract:
1. A process comprising: providing a coal tar stream; fractionating the coal tar stream into at least a naphtha range stream containing aromatics; hydrotreating the naphtha range stream in the presence of a catalyst containing molybdenum, cobalt and nickel to remove contaminants including sulfur, nitrogen, mercury, metals, or oxygenates and to saturate aromatics to produce a hydrotreated stream rich in naphthenes; separating the hydrotreated naphtha stream to provide at least a naphthene rich stream in the C dehydrogenating the naphthene rich stream to convert naphthene rich stream to aromatics to produce a dehydrogenated naphthene rich stream; provide a crude oil hydrocarbon stream containing naphthenes and paraffins from a crude oil feed; hydrotreating the crude oil hydrocarbon stream in the presence of catalyst containing at least one group VIII metal and at least one group VI metal under a condition less severe than the condition of hydrotreating of the naphtha range stream to produce a hydrotreated crude oil hydrocarbon stream; combining the dehydrogenated naphthene rich stream with the hydrotreated crude oil hydrocarbon stream to form a combined stream; and reforming the combined stream to convert the naphthenes to aromatics and provide an aromatic stream.
