Among the various processes and reactor designs in polymer cracking, catalytic cracking of
polymer dissolved in solvent offers interesting features. In the present research, catalytic
cracking of low-density polyethylene (LDPE) dissolved in benzene in a fixed-bed reactor
was studied. The catalysts used included three zeolites in original form and nickel (Ni)-
impregnated forms. The LDPE conversions achieved were high (> 98%) despite the short
retention times. The catalytic cracking of LDPE produced liquid in the gasoline range, gases …
