摘要：

The liquid-phase catalytic degradation of high density polyethylene (HDPE) was carried out over alkali-treated MOR zeolites. The catalytic activity of MOR zeolite was considerably enhanced by the treatment of 0.2 N NaOH. A partial dissolution of pore entrance - providing mesopores - caused rapid diffusion and a partial extraction of acid sites on the external surface - lowering acid site concentration - brought about suppression of carbon deposition, resulting in high conversion of HDPE degradation.
