Method for manufacturing synthesis gas from carbonaceous solids in e.g. gas turbine power plant, involves setting molar ratio, where treatment of raw gas comprises allowance of hydrogen debited to shift reaction

摘要

The method involves enabling gasification of solids with gaseous oxygen-containing gasification agents, and preparing crude gas obtained by gasification into a synthesis gas. A molar ratio from hydrogen to carbon monoxide is set depending on a type of synthesizing selection, where the treatment of the raw gas comprises allowance of hydrogen debited to a water gas shift reaction. The raw gas is obtained from an energy source selected from artificial natural gas, methanol, dimethyl ether or synthetic fuel.
