由石油化工研究院承担完成的一种管式裂解炉蒸气裂解制乙烯方法,获得国家发明专利。炼油厂的C4主要用于民用液化气,利用价值较低;如果将这部分C4产品作为裂解装置的原料,可大大提高C4产品的利用价值。这样既扩大了裂解装置的原料来源,又解决了C4产品过剩和出厂困难的问题。为此,石化院科研人员开展了C4与轻烃的共裂解研究,选择富含链烷烃的轻烃和C4混合作为管式裂解炉蒸气裂解制乙烯的原料,在保证轻烃的裂解性能和乙烯收 By the petrochemical research institute to undertake a tubular cracking furnace vapor cracking ethylene method, access to national invention patents. C4 refinery is mainly used for civil liquefied gas, the use of low value; if this part of the C4 products as raw material cracking device, C4 products can greatly enhance the value of use. This will not only expand the sources of raw materials cracker, but also solve the problem of excess C4 products and factory problems. To this end, petrochemical researchers carried out the C4 and light hydrocarbon co-cleavage study, the choice of paraffin-rich light hydrocarbons and C4 mixed as tube cracking furnace vapor cracking of ethylene raw materials, to ensure the cracking of light hydrocarbons and ethylene Close
