A comparative investigation of biomass pyrolysis on connecting tube performance for liquid smoke production

Currently, optimizations of biomass pyrolysis processes become an exciting topic. This is due to the increasing requirement of energy. This study focuses on the optimization pyrolysis process of solid waste of palm starch that became an environmental problem. The objectives of this study are to optimize the pyrolysis process of palm starch waste, especially liquid smoke product. The optimization of the liquid smoke product had conducted through the modification of connecting-tube between pyrolysis reactor and condenser. The connecting tube has differences in diameter, length, and material. The results of the study show variations in size and type of tube affect the product yield of the pyrolysis process. Stainless-steel pipes have better performance to produce liquid-smoke. The shorter the length of the pipe increases the quantity of liquid-smoke, but the smaller the diameter of the pipe decreases the quantity of liquid-smoke. This paper discusses in more detail the comparison of the performance of connecting tube by modifying the type of material, the length, and the diameter of the pipe.
