Abstract

Utilization of biomass as an energy source is very important, especially by-products from forestry, plantations, and livestock. Biomass as fuel still has many disadvantages, both in terms of water content, calories, and weight. To overcome this, a thermochemical process is needed, namely Torrefaction. Torrefaction is a heating process between 200-325°C with minimal oxygen conditions. This process is being widely used to improve the properties of biomass as fuel and reduce the weaknesses of biomass, such as low heating and energy density, high inertia, low combustion efficiency, and high milling energy. In this study of palm kernel shell, torrefaction was carried out from 0.5 cm sieve with three variations in temperature, and residence time follows 250 0C - 300 0C and 20-40 minutes then analyzed ultimately. The high heating value is predicted using ultime data calculated by the equation of Chang-Dong and Azevedo, Fried, and Özyuğuran then used to determine energy yield. The optimum process for torrefaction of palm kernel shell according to calorific value and energy yield is 275 0C with residence time 20 minutes.
