Pyroysis of an LDPE-LLDPE-EVA copolymer mixture with used-HZSM-5 catalyst |
| 초록 |
The present work is aimed at studying the performance of used-HZSM-5 catalyst in the catalytic cracking of an EVA copolymer+LDPE+LLDPE, with a composition similar to that found in real agricultural film wastes. The crystallinity, amount of acid site and surface area of a used-HZSM-5 decreaesd a little than those of a fresh HZSM-5, but the catalytic performance of a used-HZSM-5 could be achieved in pyrolysis of polymer mixture. When the polymer mixture was brought into contact with used catalyst (liquid phase contact), a gaseous products yield of 66.5% was obtained. Used-HZSM-5 gave rise to a high selectivity valuable C3~C4 hydrocarbons, most of them olefins. The selectivity to isobutene over used-HZSM-5 was much higher than that of thermal degradation. |
