煤系共伴生油页岩热解残渣利用技术

油页岩残渣是油页岩热解过程中排放的固体废物,约占油页岩的80%~90%。中国油页岩残渣利用率较低,残渣堆积量日益增多,后续问题十分突出。煤系油页岩残渣的资源化利用成为油页岩热解提油产业发展的瓶颈。介绍了油页岩热解加工利用现状及其残渣在废水处理和废气吸附方面的应用,分析了当前页岩热解残渣利用过程中存在利用方式单一的问题,并结合油页岩热解残渣结构和组成的特殊性,提出了油页岩残渣用作环保材料如吸附剂的发展方向。 The solid waste which is produced in oil shale pyrolysis is oil shale residue,accounting for approximately 80% to 90% of oil shale mass.The resource utilization of coal-derived oil shale residue had become the bottleneck of oil shale pyrolysis industry due to its low utilization rate and increasing yield.This paper investigated the situation of oil shale pyrolysis and the application of residue in waste water and waste gas treatment.The results showed that,the single utilization of oil shale residue restricted its further use.Combined with its special composition and structure,this paper put forward that the oil shale residue could be used as environmental material such as adsorbent
