【本刊讯】从中国石油石油化工研究院传出消息,由该院完成的一种管式裂解炉蒸汽裂解制乙烯的方法获得国家发明专利授权。该技术通过将碳四与富含链烷烃的轻烃混合进行共裂解,提高了副产碳四产品的乙烯收率,拓宽了乙烯原料的来源,改善了原料结构和整体品质。据介绍,该技术克服了碳四原料单独作为裂解原料使用时乙烯收率不到18%、裂解炉管结焦严重、影响乙烯裂解炉运行周期的缺点。由 【News from】 China Petrochemical Research Institute came news came from the hospital completed a tubular cracking furnace steam cracking ethylene obtained national invention patent authorization. By co-cleaving carbon tetrakis and paraffin-rich light hydrocarbons, the technology increases the ethylene yield of the byproduct carbon four products, broadens the sources of the ethylene raw materials, and improves the raw material structure and the overall quality. According to reports, the technology to overcome the four carbon alone when used as a cracking feedstock ethylene yield of less than 18%, pyrolysis furnace tube coking serious impact ethylene cracking furnace operating cycle shortcomings. by
