Abstract: A self-contained system for the generation of electrical energy from biomass by gasification combines several process units in one self-contained system. The global properties are greater than the sum of the individual properties of the process units.

Abstract: In a process for the synthetic generation of methane from a feed gas mixture, a feed gas mixture including carbon monoxide, hydrogen, water vapor, CO2, volatile hydrocarbons comprising C2 and higher, unsaturated C2 components and aromatic hydrocarbons in the range of 1 to 10 vol % is provided. The feed gas mixture is contacted with a fluidized bed catalyst having catalyst particles having a catalytic active component selected from the group consisting of a metal, a metal compound and combinations thereof. The contacting occurs at an elevated temperature in the range of 250 to 450° C., a feed gas pressure in the range of 0.8 to 70 bar, a gas hourly space velocity of 1000 to 50000 h?1, and a concentration of H2/CO in the gas mixture in the range of 0.25 to 5.

Abstract: A method for converting a raw gas into a methane-rich and/or hydrogen-rich gas includes the following steps: a) providing the raw gas stemming from a coal and/or biomass gasification process, thereby the raw gas comprising beside a methane and hydrogen content carbon monoxide, carbon dioxide, alkanes, alkenes, alkynes, tar, especially benzole and naphthalene, COS, hydrogen sulfide and organic sulfur compounds, especially thiophenes; thereby the ratio of hydrogen to carbon monoxide ranges from 0.3 to 4; b) bringing this raw gas into contact with a catalyst in a fluidized bed reactor at temperatures above 200° C.
