| PTA(Pure Terephthalic Acid)is producing compound polyester fibre and plastic importance materials,mostly adopting p- dimethylbenzene(PX)air oxidation method to produce。Near tims,as a result of polyester technical high speed developing in china,caused the severitybe hard up of PTA,in china the consumption of PTA exceed output of 1/3 on the world,reach crore ton about, thereinto halfhalflings moiety upwards of production depend on import。In china from 1970s begin a great deal repeat fetch in PTA device,to this day that have 16 sets alreaday,not only include Dupond,BP,Mitsui Petrochemical,Eastman miscellaneous mainstream technics,also included these companys in the differ age and scope of ability device,that kind of complete,all over the world unique。Now even have many device to fetch in of plan in process are authorized。For come true PTA technology and device homemade,in National Development and Reform Commission of China energetically sustain ing,Jinan Zhenghao Advanced Fibre co.Ltd with Cina Textie Indistyiai Engineering Instihme,ZheJiang University,TianJin University cooperatling laim at PTA process outspread systemic chemical investigation。By continual o flaboratory research,mathematics simulation,industry experimentation,get over a good many difficulties,ration command oxidation react mechanism and dynamics disciplinarian,oxidation reactor operating characteristic,empolder new type that having freedom intellectual property rights oxidation reactor,and advanced oxidation technics,investigation fruit in concerned bear on corporation of additionalteration,industry experiment,technics software bag exploitation gained blest apply。Now homemade PTA whole set technic and principium design have put in actualizing phase,PTA technology and device history to be fetch in hopeful as soon as possibleto be end。This article particular address oneself to upwards disquisition process from reaction elements,reaction dynamics,optimizing of reaction condition,alteration oxidation reactor。... |
