Abstract:
1. A process for producing hydrocarbon compounds comprising: a) providing to a first reverse water gas shift reactor hydrogen gas and carbon dioxide gas, wherein the molar ratio of hydrogen gas to carbon dioxide gas is greater than one, to generate a first syngas stream comprising a mixture of at least carbon monoxide gas and hydrogen gas, water steam, and residual carbon dioxide gas; b) generating a second syngas stream from the first syngas stream by condensing and removing at least some water steam from the first syngas stream; c) providing the second syngas stream to a second reverse water gas shift reactor to generate a third syngas stream comprising a mixture of at least carbon monoxide gas and hydrogen gas, water steam, and residual carbon dioxide; d) generating a fourth syngas stream from the third syngas stream by condensing and removing at least some water steam from the third syngas stream, and; e) generating a mixture of at least hydrocarbon compounds from at least the carbon monoxide gas and the hydrogen gas from the fourth syngas stream, wherein steps c) and d) are repeated with one or more added sequentially arranged reverse water gas shift reactors.
