由于乙炔含量对后续聚合过程的巨大影响,使得碳二加氢单元成为乙烯装置中至关重要的一环。因此,碳二加氢催化剂技术是整个乙烯技术中的关键技术之一。拥有自主知识产权的碳二选择加氢催化剂的开发与应用,可大大减轻国内乙烯装置对国外技术的依赖,对保证我国能源与经济安全、提高乙烯工业的竞争地位有重要意义。中国石油石油化工研究院于1997年开始进行碳二加氢催化剂(LY-C2-02)的开发,2003年首次在中国石油兰州石化公司24万t/a乙烯装置进行工业应用试验,
Due to the huge influence of acetylene content on the subsequent polymerization process, the carbon two hydrogenation unit becomes an essential part of the ethylene plant. Therefore, carbon two hydrogenation catalyst technology is one of the key technologies in the whole ethylene technology. The development and application of carbon-2 selective hydrogenation catalysts with independent intellectual property rights can greatly reduce the dependence of domestic ethylene plants on foreign technologies and are of great significance to ensuring China’s energy and economic security and enhancing the competitive position of the ethylene industry. PetroChina Research Institute of Petroleum and Petrochemical started the development of carbon-2 hydrogenation catalyst (LY-C2-02) in 1997 and for the first time in 2003, it carried out industrial application tests on the 240,000 t / a ethylene unit of PetroChina Lanzhou Petrochemical Company,
