METHOD FOR PRODUCING A LOW-EMISSION FUEL GAS

摘要

The invention relates to a method for producing a low-emission fuel gas (T) that is suitable for operating an internal combustion engine (1), in particular for a spark-ignition gas engine, wherein a fuel (F, F') is converted into a synthesis gas in a gasification process or a reforming process and the synthesis gas thus produced is subjected to a shift process, whereby the proportion of the chemical energy of the synthesis gas that is contained in hydrogen is increased, wherein CO2 contained in the synthesis gas is removed in a removal process after the shift process, wherein an exhaust gas (A) emitted by the internal combustion engine (1) is added to the gas mixture of synthesis gas and air.
