Abstract
The aim of the present work is to study the effect of gallium addition to HZSM-5 on recovery rates of gaseous and liquid products and carbon number distribution in the catalytic cracking of a polymer mixture, LDPE, LLDPE, and EVA copolymer, with a composition similar to that found in real agricultural film wastes. Ga/HZSM-5 system produced a larger amount of aromatic hydrocarbons than HZSM-5. The yield of aromatic compound in vapor phase contact was higher than that in liquid phase contact. The yield of aromatic compound increased with the amount of catalyst and with the reaction temperature of catalyst bed. The effect of gallium addition on the carbon number distribution was not great.
