Process and apparatus for thermal treatment and chemical conversion of natural or synthetic materials to a product gas

摘要

Thermally treating and chemically converting natural and synthetic materials comprises mixing a water-containing starting material with an intermediate product of an intermediate product stream and decomposing and gasifying. Thermally treating and chemically converting natural and synthetic materials comprises mixing a water-containing starting material with an intermediate product of an intermediate product stream from the high temperature chamber (4) of a carbonization reactor (1) and decomposing and gasifying in the mixing chamber (2) of the reactor at temperatures above 300 degrees C; producing an intermediate product in connection with an additional gas supply at 500-1000 degrees C in the high temperature chamber and feeding a product stream of the mixture made of intermediate product and water-containing starting material bidirectionally as intermediate product stream between the high temperature chamber and the mixing chamber so that the intermediate product is produced by a high temperature treatment in the high temperature chamber. An Independent claim is also included for an apparatus for carrying out the process.
