Effects of the acidities and pore structures of ZSM-5 and Al-MCM-41 catalysts on the Cracking of polyolefins(HDPE, PP and PS) were studied using a semibatch reactor system. To investigate the effect of pore structure in detail, each catalysts was silane-treated. ZSM-5 showed a higher catalytic activity for the cracking of a linear polyolefin(HDPE) due to its superior acidic properties, however, its narrow pore opening was to result less cracking activity for the branched polyolefins(PP and PS). On the other hand, Al-MCM-41 has a proper acidic properties and a large pore opening, and it was found to be compatible for the cracking of bulky oligomers and branched polyolfins. |
