HYDROCARBON AND ALCOHOL FUELS FROM VARIABLE, RENEWABLE ENERGY AT VERY HIGH EFFICIENCY

摘要

A Renewable Fischer Tropsch Synthesis (RFTS) process produces hydrocarbons andalcohol fuels from wind energy,waste CO2 and water. The process includes (A) electrolyzing water to generatehydrogen and oxygen, (B) generating syngas ina reverse water gas shift (RWGS) reactor, (C) driving the RWGS reaction to theright by condensing water from the RWGS productsand separating CO using a CuA1C14-aromatic complexing method, (D) using acompressor with variable stator nozzles, (E) carryingout the FTS reactions in a high-temperature multi-tubular reactor, (F)separating the FTS products using high-pressure fractionalcondensation, (G) separating CO2 from product streams for recycling throughthe RWGS reactor, and (H) using control methods tomaintain temperatures of the reactors, electrolyzer, and condensers at optimathat are functions of the flow rate. The RFTS processmay also include heat engines, a refrigeration cycle utilizing compressedoxygen, and a dual-source organic Rankine cycle.
