Liquid Hydrocarbon Fuels From Methane and CO2
Customer: US Department of Energy
Technology: Plasma Reforming, Solid Oxide Electrolysis, Fischer-Tropsch Synthesis
OxEon Energy and Environmental Products & Technologies Corporation (EPT) will conduct an engineering-scale demonstration, producing liquid hydrocarbon fuels using both the methane and CO2 generated in EPT’s food waste digester. The EPT food waste digester in Burley Idaho sells produced biogas into a natural gas pipeline after separating and venting the bio-CO2. The proposed project will convert the bio-methane to synthesis gas (syngas, as CO & H2) using OxEon’s non-thermal plasma catalyzed autothermal reformer. To achieve high bio-carbon utilization, OxEon’s high temperature solid oxide co-electrolysis (HTCE) system will electrochemically generate additional syngas from a proportional fraction of the bio-CO2 combined with steam raised by cooling the Fischer Tropsch (FT) reactor.
Syngas from the reformed methane and co-electrolyzed CO2, will be converted to liquid fuels using a proven OxEon FT reactor design. Each of the technology components have been field tested independently and will be combined for the first time in this project. The project outcome will be an engineering scale demonstration of liquid hydrocarbon bio-fuel production achieving > 50% conversion to liquids of the biogenic carbon in both CH4 & CO2 produced by an anaerobic digester.
