Abstract

The aim of this study is to produce liquid smoke which will be used as a pesticide by means of pyrolysis of a mixture of two types of biomass- empty fruit bunches with coconut shells. The parameters used are the ratio of the mixture of the two raw materials and the pyrolyse temperature of between 250 and 450 oC. A reactor of 2 kg capacity with indirect heating is used for the process. Heat is obtained from burning LPG using a burner. Raw materials, in the form of pieces of coconut shells and empty bunches according to the size planned to be used as raw materials, are first dried using solar energy until they reach a standard drynes. During process, the smoke is passed through the cyclone to reduce tar levels, and then flows into the condenser with a water cooling fluid. After the specified duration of pyrolysis is reached, the LPG was stopped and the furnace is left for some time for cooling. After that, pyrolysis products (charcoal and liquid smoke) are taken and laboratory tests will be carried out. The influence of operating parameters such as temperature, heating rate, process duration, and raw material characteristics will be associated with the quality of the products produced, and testing will continue to be carried out until high-quality pyrolysis products are obtained.
