利用废橡胶提高冶金焦化产物质量的研究 总被引:1,自引:0,他引:1
利用2kg热解装置模拟冶金工业高温焦化工艺,对煤配加废橡胶共炼焦产物特性进行研究.结果表明,共炼焦可改善煤气组成,增加H2、CH4含量,至少提高煤气热值23%,提高煤焦油收率和质量,并且废橡胶颗粒度明显影响焦炭质量.与原煤单独炼焦焦炭相比,在煤中配加1%、颗粒度为φ<0.20 mm的废橡胶共焦化时,焦炭抗碎强度M20提高3.6%、反应后强度提高4.2%、反应性降低3.5%、硫含量不增加、降低灰分和氮含量;煤气中硫化氢浓度增加约30%.废橡胶配煤炼焦虽使硫化氢浓度有所增加,但可提高焦化产品质量. 相似文献

首钢废塑料处理新工艺的研究进展 总被引:1,自引:0,他引:1
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. 相似文献

随着煤岩测定技术的进步,炼焦煤的煤岩性质已在炼焦配煤中得到广泛应用。通过对多种单种煤和配合煤的煤岩特征以及对应的40 kg试验焦炉所炼焦炭的性质进行分析和比较,结果表明:单煤种的R0max在1.3%~15%间,所炼制焦炭的冷态机械强度(M40和M10)最好,其热性质(反应性CRI和反应后强度CSR)也较好;配合煤反射率分布图特征越接近正态分布,则所炼制的焦炭冷态机械强度(M40、M10)就较好,配合煤反射率分布图特征偏离正态分布越远,其焦炭热性质越差;40 kg试验焦炉所得焦炭的反应性CRI高,其反应后强度CSR较低,存在负相关线形关系。 相似文献

AbstractDisposal of waste plastics is a serious global issue, and hence it is imperative to explore methods to recycle them for efficient utilisation. The coke making process is considered to be a promising area to which the thermal decomposition of waste plastics is applicable, because the process involves coal carbonisation at a high temperature under a reducing atmosphere. As an outcome of the research work carried out on a laboratory scale followed by plant trials at Tata Steel, it was found that waste plastics recycling process using stamp charged coke ovens is feasible to recover coke, tar, light oil and gas from general waste plastics mixed in coal by carbonisation in coke ovens. It has also been established in the laboratory that waste plastics up to 1% can be used in coke making without any deterioration in coke strength. Plant trials have also indicated that co-carbonisation of waste plastics with coal is a possible solution for its disposal. 相似文献

The coke and coal chemicals plant at the Novokuznetsk Metallurgical Combine is making trial use of a technology that recycles
waste products in “tar ponds.” Specialists from the ékomash company have installed a recycling unit in one area of the plant’s
dump, the unit including an inclined conveyor with a steam heater and a receiving hopper. The coal preparation shop receives
the wastes in a heated bin, where a screw mixes the wastes with part of the charge for the coking ovens. The mixture subsequently
travels along a moving conveyor belt together with the rest of the charge materials. The addition of up to 2% resin-bearing
waste materials to the coal charge has not had any significant effect on the strength properties of the coke.

在炼焦煤中配入一定量的废塑料,利用20kg焦炉进行炼焦实验,分析所得焦炭的产率、冷态和热态强度。实验结果表明,其焦炭的产率均比未加废塑料的要高(除添加0.5%聚乙烯(PE)外);焦炭的抗碎强度(M30)整体呈下降趋势,耐磨性强度(M10)整体降低;焦炭的反应性(CRD出现整体升高趋势,相应的反应后强度(CSR)呈整体降低趋势。 相似文献
