PLASTIC WASTES CATALYTIC CRACKING PROCESS

摘要

The invention relates to a process for the catalytic cracking of plastic wastes by directly contacting said plastic wastes in molten state with a catalytic cracking catalyst with the purpose of breaking the long polymeric chains of the plastic materials and obtaining liquid hydrocarbons, waxes and gaseous hydrocarbons having a lower molecular weight as main products. Fresh or balanced FCC catalysts (residual catalyst from the process) are used as catalytic cracking catalysts.
