Status and Future Opportunities for Conversion of Synthesis Gas to Liquid Energy Fuels: Final Report

    Research output: NRELTechnical Report


    This report provides an account and evaluative assessment of advances in technology for manufacturing liquid energy fuels from synthesis gas (hydrogen and carbon oxides) and suggests opportunities for future research on installating practical processes. The report summarizes significant progress achieved for synthesis of oxygenate and hydrocarbon fuels on all technological levels-scientificresearch, engineering development, and pioneering plant installations. Improved synthesis technology provided by novel catalysts, innovative engineering for plant simplification, and methodology for coproduction of chemicals or electricity are reviewed for oxygenate fuels. For hydrogen fuels, improvements achieved by utilizing fixed fluid-bed synthesis, a novel combination of middle distillatesynthesis plus hydrocracking, and promising slurry-phase operation are reviewed. The report also summarizes new understanding of the chemistry of syngas catalysis, including economic considerations with new emphasis on fuel performance values; opportunities to improve synfuel economics by technology; and specific opportunities for future research. Manufacture of syngas from coal, gas, or biomassis not part of this study.
