Pyrolysis of Waste Polyolefin’s and E-component to Produce Renewable Green Fuel (RGF) Over CdCO3

Abstract

The interest and relevance of the present paper is in the current waste plastics valorization scenario. The rapid depletion of fossil sources carbon as crude oil and their ever-increasing costs has led to an intensive search for alternative fuels. The renewable green fuel (RGF) or alternative fuel was obtained from waste low and high-density polyethylene (LD-PE, HD-PE) or polyolefin’s and computer-body through pyrolysis process using a CdCO3 from 23 °C to 400 °C. Five types of hydrocarbons were observed through 2D GCxGC/TOFMS, such as 7.621 % paraffin’s, 53.66 % branched / cyclic hydrocarbons, 14.83 % aromatics, 0.37 % phenanthrenes, and some unclassified compounds were 27.11 %. The research octane number of RGF was 88.29. The bromine number of RGF is 34.03 %. RGF was suitable for diesel engines and diesel furnaces without any upgrading. During the first, second and third pyrolysis experiments, 98 g, 95 g and 100 g (wt %) waste granules with 2 g, 5 g and 0 g (wt %) CdCO3 into RGFs were 85 %, 89 % and 80 % collected; uncondensed gases were 14.22 %, 10.15 % and 19.52 % collected; the residue were 0.78 %, 0.85 % and 0.48 % collected.
