초록
Biomass is considered one of the most promising renewable energy sources, which are being actively researched due tothe depletion of fossil fuels and the global warming issue. Biocrude-oil can be produced through the fast pyrolysis of various biomassfeedstocks, such as wood, crops and agricultural and forestry residues. Because the heat transfer from the hot sand to the biomassparticles is important in the fast pyrolysis process, the particle size is one of the key factors involved in controlling the fast pyrolysisprocess. In this study, PKS (Palm Kernel Shell) was used for fast pyrolysis to study the effect of the biomass particle size on the fastpyrolysis characteristics in a tilted-slide reactor with a biomass capacity of 20 kg/h. The raw biomass was crushed and ground first,and the resulting particles were sieved into three ranges of particle size, d < 0.5 mm, 0.5 mm < d < 1.0 mm, and 1.0 mm < d < 2.0 mm. At a low pyrolysis temperature, the biocrude-oil yield increased with increasing particle size, while at medium and high temperaturesthe yield did not show much variation with the particle size. The heating value of the biocrude-oil increased with increasing particlesize at low temperature, while it decreased significantly at high temperature.

In this study, PKS (Palm Kernel Shell) was used for fast pyrolysis to study the effect of the biomass particle size on the fastpyrolysis characteristics in a tilted-slide reactor with a biomass capacity of 20 kg/h.
