Gasification of raw glycerine

摘要

The method for processing a glycerin-containing reactant mixture (G) to an intermediate product for producing a hydrogen-containing product mixture from the intermediate product by pyrolysis (3) to obtain a pyrolysis product and catalytic reaction of the pyrolysis product, comprises partially evaporating the reactant mixture at 200-220[deg] C and an absolute pressure of 50-85 mbar by thin-film evaporation (1) to obtain an evaporation product (V), washing (2) the evaporation product in a washer, and introducing crude glycerin or sub-standard glycerin from biodiesel production as reactant mixture. The method for processing a glycerin-containing reactant mixture (G) to an intermediate product for producing a hydrogen-containing product mixture from the intermediate product by pyrolysis (3) to obtain a pyrolysis product and catalytic reaction of the pyrolysis product, comprises partially evaporating the reactant mixture at 200-220[deg] C and an absolute pressure of 50-85 mbar by thin-film evaporation (1) to obtain an evaporation product (V), washing (2) the evaporation product in a washer, introducing crude glycerin or sub-standard glycerin from biodiesel production as reactant mixture, and pre-treating the reactant mixture by cleaning, drying and/or saponification. Independent claims are included for: (1) a method for producing a hydrogen-containing product mixture from an intermediate product produced from a reactant mixture; and (2) a device for producing a hydrogen-containing product mixture from an intermediate product produced from a reactant mixture.
