Abstract:
1. A method for the conversion of carbonaceous feedstock into gas comprising plasma reformulated gas of a defined composition, the method comprising the steps of: a) feeding the feedstock to a first zone of a gasifier, the gasifier comprising two or more substantially laterally distributed processing zones and configured to promote, in succession, drying, volatilization and char-to-ash conversion; b) laterally transferring the feedstock through each zone of the gasifier as a reactant material and processing the reactant material, thereby sequentially promoting drying, volatilization, char-to-ash conversion, to provide raw offgas and/or syngas; and c) reformulating the raw off-gas and/or syngas into a gas comprising plasma reformulated gas by the application of plasma heat, the gas comprising plasma reformulated gas containing higher levels of CO and H
