Claim Text:
1. An integrated hydroprocessing, steam pyrolysis and catalytic cracking process for production of olefinic and aromatic petrochemicals from a crude oil feed, the process comprising: a. charging the crude oil and hydrogen to a hydroprocessing zone operating under conditions effective to produce a hydroprocessed effluent having a reduced content of contaminants, an increased paraffinicity, reduced Bureau of Mines Correlation Index, and an increased American Petroleum Institute gravity; b. thermally cracking at least a portion of the hydroprocessed effluent in the presence of steam in a steam pyrolysis zone to produce a mixed product stream; c. catalytically cracking residuals or bottoms derived from a combined product stream, and optionally one or more of the hydroprocessed effluent or a heated stream within the steam pyrolysis zone, to produce catalytically cracked products; d. separating the combined product stream including thermally cracked products and catalytically cracked products; e. purifying hydrogen recovered in step (d) and recycling it to step (a); f. recovering olefins and aromatics from the separated combined product stream; and g. recovering pyrolysis fuel oil from the separated combined product stream for use as at least a portion of the residuals or bottoms cracked in step (c).
