Transient uptake curves for propane gas in a bed of HZSM-5 using volumetric frequency response setup (batch system) were obtained. Thereby, perturbation, such as change volume, was applied to the solid/gas system, and resulting pressure detected. Two cases mass transfer limitations (bed diffusion control micropore control) compared, it concluded that, presented case, is rate-determining process...

Abstract The present work deals with the chemical recycling of waste polypropylene via thermocatalytic pyrolysis over HZSM‐5 zeolite catalysts. main aim was to systematically investigate influence reactor configuration, acidity, wastes, obtained from different sources, as well catalyst regeneration on product distribution. It demonstrated that configuration and acid site density catalysts stron...
