废橡胶热裂解技术现状及发展方向

废橡胶是继白色污染之后又一大污染——黑色污染,是世界性的又一大难题,其中比重最大的就是废轮胎,世界各国尤其是发达国家纷纷致力于轮胎的回收利用研究.特别是其回收产品的再利用:一方面解决资源的短缺;另一方面获取较高的经济价值.经长期的探究,人们发现与翻新、制造胶粉和再生胶、作沥青填料、直接作为燃料焚烧等处理方法相比,热裂解...

Current status and development direction of waste rubber pyrolysis technology

Following after the white pollution,waste rubber is another major pollution-black pollution,which is another major problem worldwide.Among them,the largest proportion is waste tires.Countries around the world,especially developed countries,have devoted themselves to tire recycling research.Especially the reuse of its recycled products:on the one hand to solve the shortage of resources,on the other hand to obtain higher economic value.After long-term research,people have found that compared with treatment methods such as retreading,manufacturing rubber powder and reclaimed rubber,as asphalt filler,and directly as fuel incineration,pyrolysis is one of the best ways to treat waste tires.It has the characteristics of large processing capacity,no secondary pollution,and realization of resource recycling.It makes waste tires just misplaced treasures and is called"black gold".This article will briefly introduce the recycling of waste rubber,its source,hazards,and the scope of pyrolysis.Finally,it discusses the process of recycling waste rubber by pyrolysis,the application of pyrolysis products(pyrolysis oil,pyrolysis gas,pyrolysis carbon,fiber and steel),and the future development prospects of pyrolysis technology.
