Abstract: Provided herein is a method, device and installation for devolatizing a solid feedstock, comprising carbon-based waste selected from the group consisting of hazardous material, biomass, animal manure, tires, municipal solid waste and refuse derived fuel. The method comprises treating the solid feedstock to a produce a particle size laying between about 1 cm3 and about 100 cm3. The solid feedstock is passed into a jacketed system. The solid feedstock is contacted with a heated gas, comprising hydrogen, inside the jacketed system at a temperature of about 500° C. to about 1000° C. for a time of about 60 seconds to about 120 seconds, whereby the solid feedstock is converted into a gas stream and a solid stream.
