Track: Waste

Abstract

This study relates to an assessment for the potential to produce liquid oils by co-processing coal fines with municipal solid plastics waste using red mud from aluminium processing as a catalyst. This research seeks to promote environmental sustainability by utilising waste coal fines and municipal solid waste without creating health and environmental hazards. Using municipal solid plastic waste in the process enabled large scale production which reduced costs and prevented downtimes and improved plant economics. Co-processing of coal fines with municipal waste plastics is a brilliant solution for an affordable, fuel from locally available raw materials which securing energy supply, promoting economic sustainability and protected the climatic changes associated with waste management. From experimental work, it was observed that higher temperatures and lower space velocities increase the formation of coke and gas which decreases the yield of oil. All experimental runs were conducted at 350-375 ^oC and a liquid hourly speed velocity of 0.70-1.70/ hat hydrogen pressure of 6 MPa yielding oils of 24-34 wt.% for naphtha, 34-45 wt.% for middle distillates and heavy distillates 18-25 wt.%. Co-processing of coal fines and municipal waste is a good waste valorization strategy to produce liquid fuels.
