Direct synthesis of hydrocarbons from co-electrolysis solid oxide cell
A method for generating hydrocarbons using a solid oxide electrolysis cell (SOEC) and a Fischer-Tropsch unit in a single microtubular reactor is described. This method can directly synthesize hydrocarbons from carbon dioxide and water. The method integrates high temperature co-electrolysis of H.sub.2O and CO.sub.2 and low temperature Fischer-Tropsch (F-T) process in a single microtubular reactor by designation of a temperature gradient along the axial length of the microtubular reactor. In practice, methods disclosed herein can provide direct conversion of CO.sub.2 to hydrocarbons for use as feedstock or energy storage.
Process for Producing a Fischer-Tropsch Synthesis Catalyst

Method and system for reducing CO2 emissions from industrial processes
A method and an integrated system for reducing CO.sub.2 emissions in industrial processes. The method and integrated system (100) capture carbon dioxide (CO.sub.2) gas from a first gas stream (104) with a chemical absorbent to produce a second gas stream (106) having a higher concentration of carbon monoxide (CO) gas and a lower concentration of CO.sub.2 gas as compared to first gas stream. The CO gas in the second gas stream is used to produce C.sub.5 to C.sub.20 hydrocarbons in an exothermic reaction (108) with hydrogen (H.sub.2) gas (138). At least a portion of the heat generated in the exothermic reaction is used to regenerate the chemical absorbent with the liberation of the CO.sub.2 gas (128) captured from the first gas stream. Heat captured during the exothermic reaction can, optionally, first be used to generate electricity, wherein the heat remaining after generating electricity is used to thermally regenerate the chemical absorbent.
