Low temperature gasification facility with a horizontally oriented gasifier

A facility for conversion of carbonaceous feedstock into reformulated syngas containing CO and H2, the facility comprising:

• a horizontally oriented low temperature gasifier for conversion of carbonaceous feedstock into off-gas and a solid residue, the gasifier comprising a horizontally oriented gasification chamber having one or more feedstock inputs, one or more gas outputs and a solid residue output, wherein the one or more feedstock inputs is proximal to a first end of the gasification chamber and the solid residue output is proximal to a second end of the gasification chamber;
• a chamber heating system configured to provide two or more substantially laterally distributed processing zones;
• and one or more lateral transfer units configured to laterally transfer, during processing, solid reactant material from the first end of the gasification chamber through the two or more substantially laterally distributed processing zones to the second end of the gasification chamber, thereby sequentially promoting drying, volatilization, char-to-ash conversion;
• a gas reformulating system in gaseous communication with the gasifier, the gas reformulating system comprising a gas reformulating chamber comprising one or more plasma torches and one or more inputs for oxygen sources, wherein the gas reformulating system is configured for the conversion of the off-gas into a reformulated syngas containing higher levels of CO and/or H2 than the off-gas;
• a residue conditioning system, the residue conditioning system comprising a residue conditioning chamber configured to receive the solid residue from the gasifier and output molten slag and a source of plasma heat for converting the solid residue into molten slag;
• and
• a feedback control system to regulate operation of the facility.
