Özet

Thermoset waste plastics from a cable materials
company have been processed using pyrolysis/gasification
in a fixed-bed steel reactor with cyclone separation
unit to produce fuel gas mixture consisting primarily of H2,
CH4, and CO. Initially, samples were pyrolysed at 600 C
and processed for gasification through 0.05 L min-1 dry
air at 750 C. Following samples were conducted under
direct gasification conditions at dry air flows varying 0.05,
0.1, and 0.2 L min-1 at 750 C. Transformation of solid
residual, and liquid and gas products which were obtained
at the end of the thermal processes conducted under
varying conditions was monitored. Volume percentages of
H2, CH4, and CO gases within the produced gas were
instantly measured via continuous gas analyser. It was
determined that thermoset plastic waste which can remain
in the environment without disintegration decreases in
mass by 94 % and solid forms being easy to control occur
at the end of heat treatment. Within the scope of waste-toenergy,
3100 kcal m-3 medium calorific value gas was
produced through direct gasification 750 C and optimum
air volume was 0.05 L min-1. Data management and statistical
analysis were carried out with SPSS software.
Thermochemical processing of waste plastic from waste
wire and cable materials in a fixed-bed steel reactor with a
cyclone separator achieved promising results to produce
synthetic fuel gas.
