| 摘要 |
A system and process for reducing atmospheric greenhouse gas, particularly carbon dioxide, uses, in some forms, a reactor, such as a plasma gasification reactor (PGR), to chemically reduce sequestered carbon dioxide with high heat in a carbonaceous bed to form gaseous products then used above the bed to convert biomass to lighter hydrocarbons, as well as hydrogen and carbon monoxide. In some arrangements the sequestered carbon dioxide supplied to a reactor is derived from a power plant's exhaust. The gaseous products of a reactor may be supplied to an additional reactor for processing to form liquid fuels or may be supplied as gas fuel to an electric power plant or otherwise combusted. Where the output of the CO2 conversion and the biomass conversion is converted to liquid fuels, such as ethanol, such fuels may be either applied as transportation fuels or used to generate electric power, among other uses. |
