The catalytic co-cracking of biomass, polymer waste, or brown coal could be an economical process for production of high value added aromatics components, which are obtained from crude oil currently. In this study thermal and thermo-catalytic cracking of polystyrene waste was carried out to produce aromatic hydrocarbons. A synergistic effect between the coated metal mesh and the melted polymer was observed, that promoted the production of liquid aromatics fraction significantly.

Thermo-catalytic thermal cracking processes refer to processes of the chemical industry whose input raw material are solid, liquid or gas state hydrocarbons. The purpose of technology is to produce a liquid and gas state hydrocarbon fraction with higher value. As a starting point in our research, we examined thermal cracking of solid and/or rubber waste by means of a fixed and fluid-bed (semi-batch) complex reactor system using a catalyst at 450 °C. Common features of these operations of the chemical industry are the inertised atmosphere, temperatures between 400 and 450 °C and a pressure range close to the atmosphere. However, the selected reactor design may imply a considerable difference as it largely determines the distribution and quality parameters of the valuable products formed. Our publication discusses the optimisation possibilities of reactor constructions of diverse types based on the values measured with the equipment constructed by us and experiences.
