    摘要： Some variations provide a process for producing mixed alcohols, comprising: purifying a biogas feedstock to generate a renewable natural gas stream comprising methane; introducing the renewable natural gas stream into a methane-to-syngas unit operated at effective conditions to convert the methane to a first syngas stream containing at least H2, CO, and CO2; purifying the first syngas stream, including separating the CO2 from the first syngas stream, and optionally separating some of the H2 from the first syngas stream, thereby generating a clean syngas stream; introducing the clean syngas stream into a mixed-alcohol reactor operated at effective alcohol synthesis conditions with an alcohol-synthesis catalyst, thereby generating mixed alcohols; and purifying the mixed alcohols to generate a mixed-alcohol product. The mixed-alcohol product may be blended with a hydrocarbon fuel, such as gasoline, to produce a blended fuel. The blended fuel has significantly lower carbon intensity than the base hydrocarbon fuel.

    摘要： A process for synthesising methanol is described comprising the steps of (i) passing a feed gas comprising a make-up gas containing hydrogen and carbon dioxide to a methanol synthesis loop, (ii) recovering a product gas mixture containing methanol from the methanol synthesis loop, (iii) cooling the product gas mixture to below the dew point to condense crude methanol, (iv) separating the crude methanol from an unreacted gas mixture, (v) passing a portion of the unreacted gas mixture to the methanol synthesis loop and (vi) recovering a portion of the unreacted gas mixture as a purge gas stream, characterised by contacting the crude methanol and a portion of the purge gas in a stripping unit to strip dissolved gases from the crude methanol thereby forming a stripped crude methanol and an enriched gas mixture, and feeding at least a portion of the enriched gas mixture to the methanol synthesis loop.
