Abstract

In the present work, Hydrothermal-liquefaction (HTL) reaction was investigated for kitchen waste at different temperatures 150-250 oC both in the presence and absence of hydrogen gas for the conversion of biodegradable kitchen waste into the liquid products in high pressure autoclave (batch reactor). Then the best conditions were evaluated in the presence of HZSM-5 and a composite meso/micro porous silica based HZSM-5M catalyst. It was observed that HTL in the presence of hydrogen gas and composite catalyst results higher yield of bio-oil as compared to HTL without hydrogen gas and catalyst. Highest liquid products yield was observed with 20 bar hydrogen (cold conditions) at 225 0C in the presence of catalyst HZSM-5M (64 wt %) with 10 wt % HZSM-5M catalyst.
