Production and Characterization of Bio-Oil by Pyrolysis of Mahua De-Oiled Seed Cake

摘要

The focus of this paper is to analyse the de-oiled seed cake of madhuca indica (mahua) to produce bio-oil by pyrolysis process, carry the characterisation of bio-oil and use a simple economical method for utilization in diesel engine. The suitability of de-oiled seed cake is analysed by proximate and ultimate analysis, TGA and FTIR, which reveals that the de-oiled seed cake could be a viable option of energy source. The maximum yield of bio-oil obtained was 38.6%, for the particles size of 0.85-1.25 mm at an optimum temperature of 450 8C with the heating rate of 20℃/min. The characterisation of biooil is done by density, viscosity, calorific value, flash point, moisture and ash content. The characterisation revealed that the bio-oil obtained by pyrolysis process can't be directly used in diesel engines as it is immiscible with petroleum products; hence the miscibility study of bio-oil with diesel is carried out by emulsification. Tween 20 is used as a surfactant and diethylether is used as an cetane improver so that it can be used as an alternative fuel.
