Abstract

Pyrolysis of real wastes (MPW and MSW) has been investigated at 500 degrees C, 550 degrees C and 600 degrees C using Y-zeolite, beta-zeolite, equilibrium FCC, MoO3, Ni-Mo-catalyst, HZSM-5 and Al(OH)(3) as catalysts. The viscosity of pyrolysis oils could be decreased by the using of catalysts, especially by beta-zeolite and MoO3. Both carbon frame and double bound isomerization was found in case of thermo-catalytic pyrolysis. Char morphology and texture analysis showed more coke deposits on the catalyst surface using MSW raw material. Pyrolysis oils had K, S. P Cl, Ca, Zn, Fe, Cr, Br and Sb as contaminants; and the concentrations of K, S. P, Cl and Br could be decreased by the using of catalysts. (C) 2013 Elsevier Ltd. All rights reserved.
