摘要：
In this study, to convert high moisture content waste into bio-char, slow pyrolysis of cooked rice waste was proposed. The effects of temperature and duration of slow pyrolysis of cooked rice waste on the fuel properties of the biochar produced were investigated, namely the carbon content and energy density. The cooked rice waste was dried overnight at 80°C prior to pyrolysis to reduce moisture content. The carbon content was measured by using Thermo Finnigan Flash EA 1112 Series Elemental Analyser CHNS-O. Energy density was measured by using IKA Works C—5000 Control bomb calorimeter. Results demonstrated that pyrolysed rice waste at 250°C and 4 hour duration had the highest carbon content (60.30%). Moreover, the calorific values for pyrolysed cooked rice wastes demonstrated that biochar derived from cooked rice waste could be a promising alternative renewable energy source. © 2019 Trans Tech Publications Ltd, Switzerland.
