Abstract
Using the thermogravimetric analysis technique, the catalytic effect of ferric sulfate and zinc sulfate on the pyrolysis of hemicellulose was studied. Thermograms of the pyrolysis of pure hemicellulose and hemicellulose mixed with 3 % of catalysts were obtained at heating rates of 10, 30, and 100 K/min. The effect of heating rate and catalysts on the shape of thermograms, DTG peak temperature of weight loss events, and kinetics parameters was evaluated. Results were fitted to three kinetic models. The presence of these salts strongly change the thermogram forms and DTG temperature peaks with respect to the corresponding pure hemicellulose thermograms. Data from the three systems studied were well-modeled by the distributed activation energy model, DAEM. By comparing these and the respective results of the decomposition model proposed in the literature, it is possible to infer that the sulphates under study catalyze the reactions of dehydration/fragmentation and de-polymerization of hemicellulose.
