【摘要】 首钢集团针对目前焦化工艺处理废塑料的技术现状,提出了废塑料处理新工艺,并进行了系统的理论研究与工业应用研究。研究结果表明,首钢废塑料处理新工艺打破了国际上"炼焦配煤添加废塑料与提高焦炭质量不可兼得"的观念,开发出对焦化和环境都有利的"利用焦化工艺处理废塑料新技术"。这项技术,不仅在满足焦炭质量要求的前提下扩大了炼焦配煤中添加废塑料的比例(≤4%,质量分数,下同),而且在限定废塑料添加比例(≤2%)的条件下提高了焦炭质量,为科学、合理、经济地治理"白色污染"提供了理论依据和工程经验。更多还原

【Abstract】 Nowadays,the cycle of manufacturing and consuming plastic materials has resulted in a serious environmental and economic problem,as called ’white pollution’ in the world.For this reason,disposal of waste plastics has become increasingly a concern and much efforts for recycling waste plastics have been made.Based on the traditional method of disposing waste plastics by coking process,a new method of co-coking waste plastics and blend coal was proposed by Shougang Group and investigated theoretically and experimentally.The results showed,that the new method not only can increase the content of waste plastics to ≤4% in the charge of coke oven,but also improves the quality of coke if the content of waste plastics ≤2%.The new technology has been proved economical and environmentally friendly to deal with ’white pollution’.更多还原
