In this research, catalytic cracking of low-density polyethylene (LDPE) has been carried out in the presence three kinds typical molecular sieves, including ZSM-5, HY and MCM-41, respectively. The effects different catalysts on composition quantity pyrolysis products consisting gas, oil solid material were systematically investigated summarized. Specially, added into LDPE for to obtain regulata...

Highly dispersed Co particles in MCM-41 were prepared by direct addition of CoCIz to the synthesis gel. The small clusters of Co did not sinter during reduction and sulfidation. Incorporation of Co into the MCM-41 lattice was not observed. The addition of Co to the synthesis gel did not alter the structural characteristics of the MCM-41 samples.
