METHOD AND DEVICE FOR PRODUCING ENERGY, DME (DIMETHYL ETHER) AND BIO-SILICA (ASH) USING CO2-NEUTRAL BIOGENIC REACTIVE AND INERT INGREDIENTS

摘要

Method and devices for producing biosynthesis gases and/or synthetic fuels, in particular DME (dimethyl ether) and/or bio-silica using biogenic ingredients, comprising the steps of: allothermal gasification of the biogenic ingredients by way of pulsed burners for integrated production of process heat in a fluidized bed gasifier; gasification of inert pyrolysis coke from the first gasification step in a second parallel gasification step, which operates according to the principle of an expanded or circulating fluidized bed, using oxygen/steam as the gasification means; combining at least a portion of the gasification products from the two gasifiers for common downstream processing.
