Conversion of full range crude oils with low molecular weight carbon-hydrogen fragment contributors over zeolite catalysts
First Claim
1. A method for converting a full boiling range oil charge selected from the group consisting of crude oil and syncrudes derived from coal, shale and tar sands which comprises,mixing the oil charge with at least 5 weight percent on feed of a low molecular weight carbon-hydrogen fragment contributor selected from the group consisting of methanol alone or in admixture with C2 -C5 olefins,passing the mixture thus formed in contact with a crystalline zeolite cracking catalyst under conversion conditions comprising a temperature within the range of 800°
- to 1400°
F. and an oil charge residence time within the range of 0.5 to 12 seconds, andrecovering the products of said cracking operation separate from the catalyst employed therein.

Abstract
A refinery process is described for converting desalted full range crude oils and syncrudes derived from coal, shale and tar sands. The process involves mixing and reacting the full range heavy oil feed with a low molecular weight carbon-hydrogen fragment contributor such as methanol or C2 -C5 olefins in the presence of a fluid zeolite cracking catalyst comprising mordenite.
