CATALYTIC PYROLYSIS OF WHEAT STRAW IN THE PRESENCE OF INEXPENSIVE CALCIUM - BASED CATALYSTS BY USING TGA-FTIR METHOD
Published: 29 Jul 2017
Abstract: Catalytic pyrolysis has been widely used as a convenient method for the direct conversion of biomass into liquid bio-fuels. Pyrolysis of wheat straw with or without catalysts was investigated using TGA-FTIR method in order to determine the influence of CaO, CaCO3, Ca(OH)2, and calcined dolomite catalysts on the evolution profile and relative yield of the volatile compounds. All catalysts, except Ca(OH)2, decreased the volatile matter and increased the solid residue of wheat straw. All catalysts promoted formation of olefins whereas CaCO3 advanced formation of aromatics.
Keywords: wheat straw, catalytic pyrolysis, tga-ftir method, calcium-based catalysts
