Palm kernel shells are waste from Crude Palm Oil (CPO) factories that have not been optimally utilized, so further processing is carried out to increase their economic value by the pyrolysis process. The pyrolysis process is carried out using a reactor combined with a spiral stirrer, and a condensation process that uses a refrigeration system to control the coolant temperature at 18oC. The purpose of this study was to determine the effect of particle size, temperature and residence time on the pyrolysis of palm shells sourced from the Musi Banyuasin area of South Sumatra. The pyrolysis experiments were carried out at pyrolysis temperatures of 300oC, 325oC, and 350oC and the palm shell particle sizes of -3+5 mesh and -5+7 mesh for residence time varied for 3 hours, 4 hours, and 5 hours. The maximum liquid smoke yield obtained is 28.6% at 350oC for palm shell particles -5+7 mesh and a residence time of 5 hours. In terms of temperature influence, the lowest smoke yield is 19% of the total biomass at 300oC. For the residence time variation, the maximum liquid smoke product was 28.6% of the total biomass at a size of -5+7 mesh for 5 hours.
