Production Of Liquid Biofuels By Slow Pyrolysis Of Sterculia foetida Seed

Pyrolysis of Sterculia foetida seed was performed at a heating rate of 5°C/min in nitrogen atmosphere at different temperatures of 450, 500, 550 and 600°C in order to find out the optimum temperature (550°C) for utmost liquid yield (68.8%, weight basis). The pyrolytic liquid was separated as oil and aqueous layer with a yield of 46.4% and 22.4% by weight, respectively. At an optimum temperature of 550°C, the maximum bio-oil yield of 24% was obtained alongwith 29.2% of biochar. The products of bio-oil was further physically and chemically characterized. The chemical characterization of bio-oil was carried out through FTIR analysis.
