Summary on Grant Application Form
The proposed project involves a study of the acid-catalysed thermal degradation of waste polymers. Initially, the work will focus on hydrocarbon polymers particularly polyolefins (poly-ethylene, -propylene and -styrene) and the acid catalysts will be based on hydrogen forms of zeolites in association with wider-pore matrix components. The selection of zeolite structures, compositions and modifications will be based on previous studies of polymer degradation at UMIST and on work currently in progress, under a LINK Scheme, on new FCC catalysts. Novel catalysts, both in the zeolite component and in the matrix component will be included in this study. The aim of the project is to generate valuable product streams from waste polymers and to provide kinetic and mechanistic models for use in process design. To this end the effect of important process parameters on product spectrum will be evaluated and correlated with catalyst structure and composition. Information from this study, along with estimation of heat generated by oxidative regeneration of deactivated catalysts will be used to define the reactor type/configuration for optimal processing. As the work progresses and the nature of the achievable chemistry becomes clear, links with both polymer producers and processors will be sought.
