Fuel production from plastics is attractive because it simultaneously
addresses the issues of waste management and alternative
energy generation. The optimization of conversion parameters
such as the choice of catalysts, reactor design, pyrolysis temperature,
and plastic-to-catalyst ratio plays a very important role in the
efficient processing of gasoline and diesel grade fuel. The use of a
catalyst for thermal conversion lowers the energy required for
conversion, and catalyst choice is important for efficient fuel
production. A catalyst with higher acidic properties and a higher
porosity can enhance conversion; for example, FCC catalysts catalyze
the production of aromatic and gaseous hydrocarbons,
whereas dual catalysts like zeolite and metal loaded catalysts can
be used for producing hydrocarbons and isomerized products,
which increase the octane rating of fuels. Uniform distribution of
heat and mass is another important factor in conversion.
