2012年12月,由上海石油化工研究院承担催化剂研发以及工艺包开发设计工作的中国石化重大科研项目——20万t/a甲苯甲基化制二甲苯(MTX)工业示范装置在扬子石化产出高质量的二甲苯产品,并直接送往芳烃联合装置。国外上世纪70年代开始研发甲苯甲基化制二甲苯技术,但迄今没有商业化运行的报道。上海石油化工研究院根据产业发展的形势以及中国石化的发展战略,于2009年正式立项,开展了甲苯甲基化技术的工业侧线试验研究。经过3年多的努力,相继完成了工业侧线试验和20万t/a工艺包的开发设计工作,先后成功开发了高性能的甲苯甲基化催化剂、多床层反应
In December 2012, Sinopec Corp., a major research project undertaken by Shanghai Petrochemical Research Institute to undertake catalyst development and process package development and design, a 200,000 t / a toluene methylation-based xylene (MTX) industrial demonstration plant in Yangzi Petrochemical High quality xylene products are sent directly to the aromatics complex. Abroad 70 years of last century began to develop toluene methylation of xylene technology, but so far no commercial operation of the report. According to the situation of industrial development and the development strategy of Sinopec Corp., Shanghai Petrochemical Research Institute formally started the project in 2009, carrying out industrial side-line experimental research on methylbenzene methylation technology. After more than three years of efforts, we have successively completed the industrial side-line test and the development and design of a 200,000 t / a process package. Successfully developed high performance toluene methylation catalyst, multi-bed reaction
