Abstract:

The co-pyrolysis of low-density polyethene (LDPE) with rice husk (RH) at different blend ratio was carried out in a fixed bed reactor with varying temperatures ranging from 350-550oC. The objective of this present work is to investigate the influence of different parameters such as blend ratio, co-pyrolysis temperature and feed size on their product yields. The feed size varied in the ranges from 0.5 to 2.36 mm for rice husk and 20×20 mm for LDPE. The experiments were conducted varying temperature between 350 to 5500C with an interval of 500C. The maximum bio-oil obtained for LDPE/RH co-pyrolysis was 53.38% at 450oC with 3:1 blend ratio. Various properties of the bio-oils obtained under these conditions were analyzed. According to the analysis results, the produced co-pyrolysis oil had higher carbon content, lower oxygen content with a higher heating value in comparison with biomass oil. The results of FTIR analysis showed that the co-pyrolysis oil mainly comprised of the aliphatic Compound and less aromatic Compound as compared to the individual rice husk pyrolysis. The results of this study indicated that the obtained co-pyrolysis oil could be used as a potential fuel.
