Abstract

The co-pyrolysis of sesame oil cake and the waste jute sacks has been conducted in a long tubular type semi-batch reactor in the temperature range of 573 to 1173K in N₂ atmosphere. A reaction scheme has been proposed where two parallel reactions occur simultaneously to produce volatiles and char. Kinetic parameters, namely, rate constants, frequency factors, activation energies have been determined through nonlinear regression analysis. Effects of co-pyrolysis temperature have been observed on product yields. The pH value of the oil confirmed that the oil is acidic in nature. The functional groups of the pyro-oil have been analyzed by Fourier Transform Infrared (FTIR) spectroscopy to identify the basic functional groups. The energy yield of the pyro-oil has been calculated.
