Autothermal biomass torrefaction process in the aspect of process gases analysis
Energy willow chips, alder chips, mixed sawmill chips and palm kernel shells were torrefied in a moving bed reactor at an ay. temp. 290-355 degrees C and biomass flow 86.3-109.3 kg/h for 8-25 min to produce a solid fuel and a process gas. AcOH, Me0H, furan derivatives, aldehydes, ketones, arom. hydrocarbons, PhOH derivatives, water and tar were evidenced in the process gas. It contained also some amts. of CO, H-2 and short-chain aliph. hydrocarbons.
