Pyrolysis of Polymer Waste in the Presence of Metal Chlorides of Iron Subgroup

Abstract

In this work investigation of the influence of the polymeric cord of used tires composition on the course of the catalytic pyrolysis presents. It was found that with the collaborative catalytic pyrolysis of rubber and cord in a weight ratio of 1:1 the flow rate of the process and the mass fraction of volatile products are increased, which affects the increase of the efficiency and the decrease of the power consumption of the process. While studying co-pyrolysis process of polymeric cord and biomass it was revealed that the use of iron subgroup metal chlorides as a catalyst allowed decreasing the apparent activation energy in 30 kJs/mol compared to a non-catalytic process. The application of chlorides of iron subgroup metals can lead to the increase in the yield (up to 25 %) of gaseous products with high calorific value.
