Bio Oil Dari Pirolisis Lambat Sekam Padi Basah: Sifat Fisik Dan Unsur Kimia

Abstract

Abstract :
The aim of this research is to investigate the characteristic of bio oil obtained from slow pyrolysis of wet rice husk. The focus of this research is on the chemical and the physical characteristicsof bio oil from slow pyrolysis of wet rice husk. The reseach was conducted experimentally in the laboratory. The construction of the slow pyrolysis reactor was an externally heating double pipe counter current flow heat exchanger. The rice husk entered the reactor using screw conveyor. The mass flow rate of rice husk was 5 kg/h. The reactor temperature at the wall near the flame source was controlled at 300, 400, and 500oC. The moisture content of the rice husk was 20%. The substances in the bio oil was detected by GCMS (Gas Chromatography-Mass Spectrometry) and showed that more than 15 substances were detected. The bio oil was not stable in storage more than seven days.
