  • System and process for producing synthetic liquid hydrocarbon
    Patent number: 8444725
    Abstract: Production of synthetic liquid hydrocarbon fuel from carbon containing moieties such as biomass, coal, methane, naphtha as a carbon source and hydrogen from a carbon-free energy source is disclosed. The biomass can be fed to a gasifier along with hydrogen, oxygen, steam and recycled carbon dioxide. The synthesis gas from the gasifier exhaust is sent to a liquid hydrocarbon conversion reactor to form liquid hydrocarbon molecules. Unreacted CO & H2 can be recycled to the gasifier along with CO2 from the liquid hydrocarbon conversion reactor system. Hydrogen can be obtained from electrolysis of water, thermo-chemical cycles or directly by using energy from carbon-free energy sources.

  • Integrated gasification—pyrolysis process
    Patent number: 8217210
    Abstract: A method for producing liquid hydrocarbons from biomass includes hydropyrolizing biomass with a gaseous exhaust stream formed from one of gasification and reforming of carbon containing moiety (CCM). The gaseous exhaust stream includes hydrogen (H2) and at least one of carbon monoxide (CO), carbon dioxide (CO2) and water (H2O).
