Abstract
The aim of this work is to study the feasibility and operational performance of plasmatron (plasma torch) gasification of municipal solid waste mixed with raw wood (MSW/RW) derived from the pretreatment of Steam Mechanical Heat Treatment (SMHT), as the target material (MRM). A 10Â kW plasmatron reactor is used for gasification of the MRM. The production of syngas (CO and H2) is the major component, and almost 90% of the gaseous products appear in 2Â min of reaction time, with relatively high reaction rates. The syngas yield is between 88.59 and 91.84Â vol%, and the recovery mass ratio of syngas from MRM is 45.19 down to 27.18Â wt% with and without steam with the energy yields of 59.07-111.89%. The concentrations of gaseous products from the continuous feeding of 200Â g/h are stable and higher than the average concentrations of the batch feeding of 10Â g. The residue from the plasmatron gasification with steam is between 0 and 4.52Â wt%, with the inorganic components converted into non-leachable vitrified lava, which is non-hazardous. The steam methane reforming reaction, hydrogasification reaction and Boudouard reaction all contribute to the increase in the syngas yield. It is proved that MSW can be completely converted into bioenergy using SMHT, followed by plasmatron gasification.
