Abstract:
Disclosed is a method relating to hydrocarbon production by gasification of carbonaceous material, for example, a two-stage gas washing method as a part of gas refining. Disclosed is a method for hydrogen sulfide and carbon dioxide removal from synthesis gas produced by gasification. Disclosed is a use of a combination of two chemical wash approaches. The process can be utilized as a part of biomass to liquid (BTL) process.
