Isoconversional Kinetic Analysis of Pyrolysis of Malt Waste

Abstract:

Locally available malt waste or brewers' spent grain, a by-product of brewing industry, was found to be a low cost and promising biomass for pyrolysis. A kinetic studied of pyrolysis of malt waste was investigated by non-isothermal thermogravimetric analyses (TG-DTG), applying slow heating rates, 10, 15, 30 and 50 K/min, and well-defined conditions. Activation energies and Arrhenius exponential factors were inferred by different estimation methods: Kissinger, Ozawa, Starink, K-A-S and. The methods presented energy activation values of 214 - 238.23 kJ/mol. The Literature studies found activations energies values similar to those found for sugarcane bagasse pyrolysis and other types of biomasses with predominance of hemicelluloses, cellulose and lignin, respectively.
