ABSTRACT
The necessity to move towards a sustainable economy is increasing day by day owing to various problems like climate change, increasing crude oil prices, etc. In this line, hydropyrolysis of Jatropha seed deoiled cake has been carried out at various pressures of hydrogen (1, 20, 40 and 52 bar) at 450 °C. With an increase in pressure under the experimental conditions of present study from 1 to 40 bar, the yield of bio-oil is found to have increased and beyond 40 bar the bio-oil yields have decreased. It has been observed that the liquid bio-oil yield is highest at 17 wt% at 40 bar. The FTIR spectrum of the bio-oil and char at 40 bar shows maximum functionality, indicating the clear opening of the macromolecular structure. The EDAX analysis of the hydropyrolysis char obtained at 40 bar pressure show a maximum of 85 wt% carbon and minimum of oxygen 13 wt%.
