ARANG DARI LIMBAH TEMPURUNG KELAPA SAWIT (Elaeis guineensis Jacq)

Abstract

Indonesia is the largest CPO (Crude Palm Oil) producer. CPO processing produces a large amount of solid waste (shell), which may be utilized to produce charcoal, hence providing more value-added. The objective of this study was to investigate the appropriate temperature and time of carbonization on the quality of palm shell charcoal. Three carbonization temperatures (400 C, 500 C, 600 C,) and three carbonization durations (2,3 and 4 hours) were applied. The best charcoal was obtained using 500-600 C with 2-3 hours of carbonization. The produced charcoal has 7,032,22-7,177.87 cal/g calorific value, 66.79-77.73 carbon content, 0.29-0.53 water content, 7.90-16.44 ash content, negative sulfur content, and 11.93-19-99 % volatile matter content.
