Abstract
A process for improving the overall carbon conversion efficiency of a gasification process, as well as improving the suitability of a syngas containing 0.5-10% methane for use as a feedstock for chemical production. A gasification reactor converts carbonaceous feedstock to syngas that is, in turn, utilized for a chemical production process in a chemical production reactor. An off-gas from this chemical production reactor is directed to a selective membrane that separates the off-gas into methane-rich and hydrogen-rich fractions. The hydrogen-rich fraction, is re-utilized as feedstock for the chemical production process, while the methane-enriched fraction is returned to the gasification reactor to form additional syngas.
