Characterizations of the gaseous fractions by catalytic copyrolysis of biomass and polypropylene

Catalytic copyrolysis of biomass/ polypropylene( pp) mixture was performed in airfree atmospheres. The gases were analyzed with GC. The optimum condition for C3–C4 gases production was temperature 410 °C, the biomass/ pp (in mass) mixtures ratio 1∶1. At 410°C, the copyrolysis leaded to the production of more than 30% (in mass) of gases. It should be noted that for the composition of C1–C2 hydrocarbons close to 30% (in all gaseous hydrocarbons), the composition of C3–C4 hydrocarbons 67% (in all gaseous hydrocarbons), and the distillable liquids fraction represents close 30% in mass of the final products.
