Abstract
Pyrolysis, pyrolysis-catalytic upgrading and catalytic pyrolysis have been developed to convert polypropylene waste to diesel and gasoline fractions. The result shows that polypropylene waste can be used as feedstock for cracking to oil without being cleaned. The components in gaseous products , gasoline and diesel fractions were analyzed and the RON for the gasoline obtained by three methods is 80, 87.3—90.8, 84.5～88.6 and the cetane number index for the diesel obtained are 45.35, 42.42—42.72, 40.56～45.30 respectively. Three methods were evaluated in a comprehensive view and the result shows that pyrolysis-catalytic upgrading is the most feasible way to convert plastic waste to oil in a large scale.
