After the established reuse industries have taken their requirements this leaves m (, tonnes) waste tyres; a quantity that can no longer be satisfactorily tipped. Laboratory scale experiments have shown that tyre can be pyrolised, using a molten carbonate system as the reaction medium, at rates corresponding to g tyre/min.

Design of a molten salt process for conversion of biomass into useful fuels is by: 1. Molten salt pyrolysis is a thermochemical conversion process in which biomass is fed into and heated up by a molten salt bath.

Molten salts have very high thermal stability, good heat transfer characteristics, and a catalytic effect in cracking and liquefaction of large molecules found in g: tyres. The tyre pyrolysis liquid analyzed was obtained from a process which places whole tyres onto molten zinc (– °C) providing direct heat transfer and hence rapid pyrolysis.

Moreover, they allow better recovery efficiency since the. process by-products can be used as fuels (gas, oils), for both conventional (classic. engines and heaters) and high efficiency apparatuses (gas turbines and fuel cells), or.
