Abstract

This research aims to produce bio-oil using the pyrolysis process with Crude Palm Oil (CPO) raw material based on microwave technology. The primary raw material used is palm oil. Before it used, do pre-treatment processes and testing bio-oil characteristics, which consist of testing the density, pH, and chemical composition. Then put the raw material into the peristaltic pump at a voltage of 2,2 volts for 20 minutes with bio-oil making technology using fast pyrolysis. Pyrolysis process of this research using microwave irradiation with power 900 W and microwave radiation system which is controlled by temperature control with variations 400°C, 450°C, 500°C, 550°C. Data analysis technique using descriptive statistics by illustrating or describing data collected. The pyrolysis process produces solid, liquid (bio-oil) and gas products. Temperature significantly affects the amount of oil produced on the palm oil pyrolysis process. Bio-oil products at four variations in temperature have experience differences. If the pyrolysis process temperature gets high, bio-oil produced from the pyrolysis process will be higher, while the number of solid products will decrease. The results of this research indicate that most of bio-oil from palm oil obtained at temperatures 500°C and 550°C is 12,5 ml/minutes. The characteristic properties with the highest bio-diesel content found at temperature 500°C are 35,41%.
