Rezumat:

A new recycling system for waste plastics was developed, in which waste plastic and heavy oil are mixed to produce an alternative fuel for power generation systems. It was found that for the injection of mixture fuel, heating at temperatures around 150 deg. C, was needed for a proper viscosity. In the present study, the emulsification of waste plastic and heavy oil mixtures with water is examined. Using a surfactant, emulsions of polypropylene (PP) with water have been successfully produced. In experiments, polymer fuels, as mixtures of heavy oil A and plastic, were produced at temperatures below those required for thermal cracking. The polymer fuels were emulsified in order to decrease their viscosity and enable easy injection at room temperature. The emulsified fuels with a high viscosity: 1000-3000 cSt were found to be applicable for injection and atomization in power generation systems without the need for heating the fuel lines. The emulsification of polymer fuels may be an essential technology for the efficient thermal recycling of waste plastic.
