Preliminary study on catalytic pyrolysis of jatropha de-oiled cake

Abstract

The decomposition behaviors of jatropha de-oiled cake have been examined in order to get desired liquid organic compounds. In the absence of catalyst, the pyrolysis produced a wide range of carboxylic acids and phenols. By use of catalyst, aromatics compounds are predominantly formed at 80-85% for zeolite supports, 40-70% for carbon supports and below 5% for SiO2 supports. Metal-modified carbon catalysts were found to be larger aromatic selectivities than carbon supports alone. Pyrolysis using quartz reactor was compared with Py-GC/MS results.
