The interest and relevance of the present paper are in the current waste plastic valorisation scenario. The rapid depletion of fossil source carbon as crude oil and its ever-increasing costs have led to an intensive search for alternative fuels. An alternative or renewable green fuel (RGF) was obtained from waste low- and high-density polyethylene or polyolefins and computer body plastics through a pyrolysis process using cadmium carbonate (CdCO₃) from 23 to 400°C. Five types of hydrocarbons were observed through two-dimensional gas chromatography and time-of-flight mass spectrometry (GC×GC-TOFMS): 7.621% paraffins, 53.668% branched/cyclic hydrocarbons, 14.083% aromatics, 0.327% phenanthrenes and 24.301% unclassified compounds. The research octane number of the RGF was 88.29. The bromine number of the RGF was 34.03%. The RGF was suitable for diesel engines and diesel furnaces without any upgrading. During the first, second and third pyrolysis experiments, 98, 95 and 100 g (wt%) waste granules with 2, 5 and 0 g (wt%) cadmium carbonate into RGFs were collected at 85, 89 and 80%; uncondensed gases were collected at 14.22, 10.15 and 19.52%; and the residue was collected at 0.78, 0.85 and 0.48%.

废聚烯烃和电子元件热解在碳酸镉上生产可再生绿色燃料

本文的兴趣和相关性在于当前的废塑料增值情景。作为原油的化石源碳的迅速消耗及其不断增加的成本导致了对替代燃料的密集搜索。一种替代或可再生绿色燃料 (RGF) 是通过使用碳酸镉 (CdCO ₃) 从 23 到 400°C。通过二维气相色谱和飞行时间质谱 (GC×GC-TOFMS) 观察到五种烃类：7.621% 链烷烃、53.668% 支链/环状烃、14.083% 芳烃、0.327% 菲和 24.301% 未分类化合物。RGF的研究法辛烷值为88.29。RGF的溴值为34.03%。RGF 适用于柴油发动机和柴油炉，无需任何升级。在第一次、第二次和第三次热解实验中，分别收集了 98、95 和 100 g (wt%) 的废颗粒，其中 2、5 和 0 g (wt%) 的碳酸镉转化为 RGF，分别为 85、89 和 80%；未冷凝气体在 14.22、10.15 和 19.52% 时收集；并以 0.78、0.85 和 0.48% 收集残留物。
