摘要

High-density polyethylene (HDPE) has been degraded thermally and catalytically using MgCO_3 at 450 ℃ into liquid fraction in a batch reactor. Different conditions like temperature, time and catalyst ratio were optimized for the maximum conversion of HDPE into liquid fraction. Catalytic degradation yielded 92% liquid fraction whereas 90% wax was obtained with thermal degradation. The composition of the liquid fraction was characterized by physicochemical properties of petroleum fuel tests. The catalytic liquid fraction consisted of high concentration of C_8-C_9, C_(13)-C_(14) and C_(17)-C_(18) hydrocarbons. The distillation data showed that ~50% of the fraction has boiling point in the range of gasoline and ~50% in the range of die-sel oil.
