Decomposition and characterization of bio-oil from coconut shell waste for bio-coke hybrid application as alternative energy resources

Abstract Bioenergy sources continue to be developed solve environmental problems due agricultural biomass waste and alternative energy sources. from raw materials through the pyrolysis method is a thermochemical conversion technology that produces bio-oil bio-char. The process of coconut shell (CS) with size 60 mesh at temperature 500-700°C without adding catalyst. results showed optimum decomposition occurred 700°C. Based on GC-MS analysis CS, compound consisting 58.18% phenol, 18.86% 2.6 dimethoxy-phenol, 1.35% 1-(acetyloxy)-2-propanone, 6.57% 3,5-dimethoxy-4-hydroxytoluene 2.55% 4-ethyl-2,6-methoxy-phenol was obtained. While SEM-EDS characterization bio-char contains main constituent elements, including 94.37% carbon minor elements 5.50% oxygen, 0.09% sodium 0.05% chlorine. Comprehensive shows an efficient sustainable for converting CS into material hybrid bio-coke applications as renewable source.
