【 摘 要 】

Torrefaction is a pyrolysis process with low heating rate and temperature lower than 300°C in an inert condition which transforms biomass into a low emission solid fuel with relatively high energy. Through the torrefaction process biomass can be altered so that the end product is easy to grind and simple in the supply chain. The research was aimed at designing torrefaction reactor and upgrading energy content of some Indonesian biomass. The biomass used consist of empty fruit bunches of oil palm (EFB), cassava peel solid waste, and cocopeat (waste of coconut fiber). These biomass were formed into briquette and pellet form and were torrified with 300°C temperature during 1.5 hours without air. The results of terrified biomass and non-torrefied biomass were compared after burning on the stove in term of energy content and air emission quality. The result shows that energy content of biomass have increased by 1.1 up to 1.36 times. Meanwhile emission air resulted from its combustion was met with Indonesian emission regulation.
