Pengaruh Suhu dan Waktu Pirolisis terhadap Karakteristik Arang dari Tempurung Kelapa

The increased production of coconut has by the shell produced, even though this lignin content 33.30% so it potential to be converted into charcoal through pyrolysis process. Pyrolysis is a thermal decomposition process that occurs without air or with little convert biomass charcoal. Coconut can used for coal co-firing in developing new and renewable energy. This study aimed obtain best temperature time manufacture high-calorific value accordance SNI 06-4369-1996. was carried out at temperatures 350 °C, 450 °C 550 times 2 hours, 3 hours 4 hours. results showed highest calorific produced resulting had 7,750.96 cal/g, yield 30.10%, contained 2.75% water, 2.70% ash 9.50% volatile matter.
