The Energy Yield of The Torrefied Coconut Shells

Abstract Woody and herbaceous biomasses have been utilized as biomass energy plant feedstocks that generate electricity for years. The coconut tree, classified woody biomass, flourishes throughout tropical regions. Every year, each tree can produce an average of 70 nuts or a maximum 150 nuts, with fruit consisting 15.18% shell. Philippines has approximately 2.2 million tons shells year. study aims to determine the yield when torrefied. were crushed, torrefied, analyzed elementally. Initially, calorific value raw was 30.79 MJ/kg improved 34.37 after torrefying at 275°C held 30 minutes. optimal mass 90.10%, while density 111.64%, resulting in 100.59%. Torrefaction by 11.63% optimized
