UPGRADING HYDROGEN DEFICIENT STREAMS USING HYDROGEN DONOR STREAMS IN A HYDROPYROLYSIS PROCESS

摘要

Disclosed is a method for producing olefins and aromatic compounds from a hydrogen lean carbon containing feed, the method comprising hydropyrolyzing the hydrogen lean carbon containing feed in the presence of a hydrogen donor feed under reaction conditions sufficient to produce a product comprising olefins and aromatic compounds or a hydrocarbonaceous stream, wherein the hydrocarbonaceous stream is further processed into olefins and aromatic compounds, wherein the olefins and aromatic compounds from (i) or the hydrocarbonaceous stream from (ii) are each obtained by hydrogenation of the hydrogen lean carbon containing feed with the hydrogen donor feed and cracking of carbonaceous compounds comprised in the hydrogenated feed, and wherein the hydrogen donor feed comprises a compound that donates hydrogen to carbonaceous compounds in the hydrogen lean feed.
