  • Patent number: 11787695
    Abstract: A petroleum residue stream is heated and reacted with an oxygen stream and a carbon dioxide stream in a gasification unit to produce syngas. At least a portion of the carbon monoxide is converted into carbon dioxide to produce shifted syngas. At least a portion of the shifted syngas is separated to produce a syngas feed stream. At least a portion of the syngas feed stream is converted into methanol. At least a portion of the methanol is converted into one or more alkenes (olefins). At least a portion of the methanol is reacted with carbon monoxide to produce acetic acid. Carbon dioxide produced in the process can be recycled to the gasification unit to facilitate the production of the syngas.
