Principle of Operation
The low-temperature catalytic depolymerization line is used for processing of waste plastics. This device works on the principle of depolymerization (pyrolysis) of the polymer to hydrocarbon products, which are pyrolysis oil, pyrolysis gas, and a solid residue - carbon.
Pyrolysis is the thermal decomposition of organic carbon-containing materials, while preventing the ingress of media containing oxygen or other oxidants. The input materials are heated to temperatures of 400° - 500° C, resulting in the release of volatile compounds.
When the raw material is heated above the thermal stability of the present organic substances found in the raw material, there is a cleavage of the macromolecular matrix to a stable low molecular weight liquid and gaseous products, as well as a solid residue. Burning does not occur, as it would during the incineration of waste, meaning that depolymerization technology does not produce harmful emissions and has no negative impact on the environment.
In the process of depolymerization, cracking occurs with the admixture catalyst. The catalyst lowers the required reaction temperature. One advantage of the depolymerization process at lower working temperatures is also lower fuel consumption for heating.
The catalyst is continuously added to the process, which ensures continuous and stable activity, and therefore balanced thermal conditions with a favourable effect on uniform product quality.
Ratings
