利用焦化工艺处理废塑料技术--添加剂OA的作用

利用热天平与200kg试验焦炉,研究添加剂(OA)、废塑料(WP)与首炼焦配煤(Coal)的热失重行为以及共焦化的成焦性能·结果表明废塑料、炼焦配煤与添加剂在相互重叠的热解失重温度区间内三者裂解生成的自由基相互作用(即协同效应),影响焦炭质量;添加剂OA、废塑料WP与炼焦配煤按比例1∶2∶97混合共焦化时,添加剂(OA)能够消除添加1%废塑料对焦炭质量产生的负面影响,使焦炭M40增加,M10降低,CSR升高,而CRI降低,具有显著的工业应用前景·

Disposal of Waste Plastics by Coking Process--the Effect of Organic Additive (OA)

Using a thermal balance and 200 kg pilot coke-oven, the thermal weight loss behavior and characteristics of the cokes produced from co-coking of waste plastics (WP), organic additive (OA) and the coking coal supplied by SHOUSTEEL in Beijing were studied. The results showed that the synergetic effect arising from the pyrolysis of WP, OA and the coal in their common temperature range of weight loss will affect the quality of coke. Moreover, during co-coking the mixture of 1% WP, 2% OA and 97% coking, the addition of 2% OA can eliminate the negative influence of the 1% WP on the quality of coke produced from co-coking, thus resulting in the increase of M40 and CSR and decrease of M10 and CRI obviously. Therefore, the technology proposed will have bright outlook in industrial applications.
