Bio oil from bio waste (Mahua oil cake) using fast pyrolysis process

Abstract

Biomass is a renewable resource utilized to produce bio fuel from bio waste. In this experiment, fixed bed fast pyrolysis is carried out on a model of mahua oil cake (MOC dimension) to conclude predominantly the consequences of pyrolysis temperature, MOC dimension and nitrogen gas flow rate from the pyrolysis yields. The temperature, MOC dimension and nitrogen gas flow rate were varied between 500 to 600o C, 2 mm to 6 mm and 0.2 to 0.4 liter per min (lpm). The utmost oil yield of 25.90 wt % was attained for a nitrogen gas flow rate of 0.3 lpm, particle size of 4 mm and pyrolysis temperature of 550o C. The pyrolysis oil had a calorific value of 28180 KJ/kg. The pyrolysis gas may well be utilized as a gaseous fuel. In addition, the bio-oil was illustrated by elemental, gas chromatography/mass spectrometry (GC-MS) analyzer.
