Optimization of hydrothermal gasification and liquefaction of household waste into hydrogen

Abstract

Due to rise in awareness of environmental issues led to newlinegrowth in research areas newlineresources production. Among these vast research areas, conversion of wet newlinebiomass into hydrogen has received newlinehydrothermaltechniques such liquefaction and gasification is newlineefficient pathway for processing the biomass and has recognized as promising newlinetechnology for future application. newlineroutes such as hydrothermal liquefaction (HTL) and hydrothermal newlinegasification (HTG) from hou newlinehydrothermal processing, the household waste was characterised to explore newlinethe composition of waste biomass and its properties. The result indicated the newlinebiomass possess low ash and sulphur content. Additionally newlinesuggested that heating rate of 10 newlinedegradation rate.
