摘要: Abstract Rice husk, a renewable by-product of rice milling operations, is an energy source that can be utilized to meet the increasing demands for energy. Its utilization also help millers costs husk disposal because restrictions on disposal. However, industrial in thermochemical conversion systems liberate requires knowledge its thermal characteristics proper design and modelling these systems. The degradation four varieties (Lemont, ROK 14, CP 4, Pa Potho) were investigated at three heating rates (10, 20 50°C/min) nitrogen atmosphere using technique thermogravimetric analysis between ambient temperature 700°C. rate active passive pyrolysis zones, initial temperature, residual weight 700°C determined. Increasing increased both 700°C, decreased temperature. higher cellulosic content Also, ash resulted could degraded extent 56–64%.
