Abstract: Thermal conversions of municipal solid waste (MSW) are sustainable solution in waste treatment since the amount of MSW trends to increase every year. Compared to other biochemical and physiochemical processes, their main advantages are strong reduction of solid waste in mass and volume by rapid conversion. Hence, thermal treatment preserves landfill space and time including labour expenses. In 2015, approximately 26.9 million tons of MSW was generated in Thailand but just twenty percent of those amount was sanitary disposal whereas only 150k tons was utilized in heat and electricity by thermal conversion. This paper proposes a high efficiency steam gasification as a selected thermal technology to recover energy from carbonaceous waste into form of combustible gas which is mainly hydrogen. Small dropped tube fixed bed reactor was represented as experimental gasifier. The average compositions of Thailand MSW consisting of 55 percent wt. food & kitchen waste, 22.4 percent wt. plastic (70 percent PE & 30 percent PP), 13 percent wt. paper, 1.4 percent wt. rubber & leather, 3.1 percent wt. textile and 5.1 percent wt. yard waste & biomass were utilized for gasifying feedstock. The experiments were varied by the two steam flow rates with the reaction temperatures 700-850 degrees to investigate the effect of steam quantity and temperature on hydrogen production and related compositions e.g. methane, carbon monoxide, carbon dioxide and light hydrocarbons. The results indicated the increasing of steam and temperature improved hydrogen production. Hydrogen yield reached 30.0 and 33.0 gH2 /kgMSW when steam flow rate of 0.05 and 0.13 ml/min was supplied at highest reaction temperature, respectively. In addition, energy yield of hydrogen in steam gasification overcame pyrolysis which mostly containing of light hydrocarbon. The optimized condition performed energy output as 16,015 kJ/kgsample and the energy conversion efficiency of the system was 65.2 percent.
