Investigation of Pyrolysis Parameters on the Yield and Quality of Bio-Oil from Jatropha curcas Wastes

Chapter

Abstract

Jatropha curcas pressed cake leftover after oil extraction for biodiesel production is considered as waste. Following physicochemical characterisation tests, this biomass waste was pyrolysed over a temperature range of 573.15–1073.15 K and a nitrogen linear speed range of 7.8 × 10−5–6.7 × 10−2 m/s to produce bio-oil. The heating rate and biomass grain size were fixed to constants of 50 K/min and <2 mm, respectively. The bio-oil products after yield measurements were tested for three major specifications, i.e. gross calorific value, water content and acidity, based on ASTM procedures for standard specification of pyrolysis liquid biofuels. In addition, empirical correlations between the bio-oil yield and pyrolysis parameters have been introduced for the experiments using nonlinear multiple regression method.
