PYROLYTIC LIQUID FUEL FROM RMSW USING LONG CATALYZER DOWNSTREAM IN STAGE PYROLYSIS

Abstract

The thermal degradation of Real Municipal Solid Waste (RMSW) at 500 ^oC has led to meager mass yields of liquid fuel. Therefore, this study examines the possibility of increasing the mass yield using Long Catalyser Downstream (LCD) equipped with top and bottom outlet in stage pyrolysis. Two natural catalysts, zeolite, and kaolin were activated at 500 ^oC for 2 hours and used in this experiment. Also, LCD temperature was varied between 200 ^oC and 300 ^oC while the pyrolyzer temperature was held at 500 ^oC. The experimental results showed that there was a significant increase in the mass yield of liquid fuels compared to pyrolysis with and without catalysts. The presence of LCD facilitates secondary cracking and produces short hydrocarbons ranging from RMSW feedstock. Natural zeolite catalysts have better productivity behavior compared to natural kaolin. It also leads to higher mass yields in liquid fuels.
