In order to develop a new recycling technology for waste plastics, catalytic degradation of low-densitypolyethylene has been investigated using a batch reactor system, in which the polymer thermallydegraded first and the resulting decomposed fragments underwent further cracking on H-borosilicatecatalyst. The presence of the boron catalyst was highly effective for converting the polymer into suchlower alkenes as propene, butenes, and pentenes. Propene was more produced with decreasing thermaldegradation temperature and increasing catalytic degradation temperature. However, the yield of thealkenes produced in the batch system was lower than that obtained in a fixed-bed flow reactor system.An excessive occurrence of the thermal degradation of polyethylene in the former might lead to alowering of the alkenes yield, suggesting that the primary thermal reaction should be properlycontrolled to produce lower alkenes selectively in the subsequent catalytic process.
