Our 50-gallon-per-day pilot plant converts natural gas and anaerobic biodigester gas to mixed alcohols, predominantly ethanol. In partnership with Novus Energy, LLC (http://www.novus-energy.com/), the plant is being used to perform test production runs for evaluating gasoline blends and characterizing process emissions and effluents for permitting requirements. Synthesis gas is generated using a dual steam-methane/CO2-methane reformer developed in collaboration with Novus Energy. The reformer uses a catalyst provided by Oxford Catalysts. A fixed-bed reactor and a slurry bubble-column reactor convert synthesis gas to fuels using a combination of a commercial methanol catalyst and WRI's proprietary ethanol catalyst. The plant also features a distillation column for product purification and a Rectisol system for CO2 separation. WRI has equipped the pilot plant with multiple flow meters, temperature transmitters, level transmitters, and pressure transducers for determining mass and energy balance over the entire system.
WRI also operates a bench-scale catalytic partial oxidation (POX) reactor that allows us to convert gaseous hydrocarbons to synthesis gas. In related research, we have begun a jointly sponsored project with Bioconversion Technology to demonstrate an advanced fuel-flexible gasifier for the conversion of solid opportunity fuels, including coal and biomass.
