Abstract

The laser processing becomes more and more popular for different objects and purposes including different fuels and combustibles. We have investigated experimentally some details of the light-induced conversion of the waste-derived coal-water slurry into the syngas. The process was “cold” enough (the temperature of the fuel was less than 350 K). The specific gasification energy strongly depends on the chosen content of the raw fuel and does not exceed the 6 MJ/kg. It was shown that there are two possible alternative processes with dominant production of the hydrogen or methane. The production of the combustible gases is accompanied with generation of certain amounts of SO2 and much less amount of CO.
