The Influence Of Feedstock Type And Processing Parameters On Scrap Tyre Pyrolysis
The paper presents the results of an experimental study conducted on different scrap tyres types using pyrolysis
processing for derived fuels production. The influence of processing parameters (process peak temperature, residence time)
and tyre type on process kinetics and reaction products formation was investigated. A wide process peak temperature range
from 350°C to 750°C was applied to representative feedstock samples using a tubular batch reactor under atmospheric
pressure pyrolysis conditions. The solid and liquid fractions of the reaction products were analysed with respect to chemical
composition and specific energy content. The pollutant chemical components migration was observed from the solid matrix
of the samples into the reaction products. The experiments revealed 450°C to be an optimum peak processing temperature
for waste to derived fuels conversion with minimum energy consumption. The results revealed significant differences
between the two analysed feedstock with respect to the samples mass loss rate, reaction products distribution, chemical
composition and specific energy content.
