随着我国社会主义革命和建设的迅猛发展,对于三大合成材料的基础原料苯和二甲苯的需要量增长很快,而从铂重整得到的三苯中,用途较少的甲苯却占有50％。因此将甲苯歧化转化为更急需的苯和二甲苯,是解决三苯供需不平衡的一种途径,是石油三次加工的一种手段。在国外,甲苯歧化法已有工业化的报导。为了加快我国石油化工技术的发展,突破基础原料技术关,根据国民经济发展的需要,我们开展了甲苯歧化催化剂的研究工作。遵照伟大领袖毛主席的教导“中国人民有志气,有能力,一定要在不远的将来赶上
With the rapid development of socialist revolution and construction in our country, the demand for benzene and xylene, which are the basic raw materials for the three major synthetic materials, has increased rapidly. However, among the triphenylbenzene obtained from platinum reforming, the less-used toluene accounts for 50 %. Therefore, toluene disproportionation into more urgent need for benzene and xylene, is to solve the imbalance between supply and demand of triphenyls one way is a means of petroleum processing. Abroad, toluene disproportionation has been reported in industrialized countries. In order to speed up the development of petrochemical technology in our country and break through the technology of basic raw materials, according to the needs of national economic development, we carry out the research work of toluene disproportionation catalyst. Follow the teachings of Chairman Mao, the great leader. "The Chinese people are ambitious and competent and must catch up in the near future
