随着我国社会主义建设事业的迅猛发展和人民生活水平的日益提高,对于三大合成材料特别是合成纤维的基本原料苯和二甲苯的需要量增加很快。因此采用甲苯歧化法从石油炼制得到的大量甲苯转化为苯和二甲苯是解决三苯供求不平衡的一个重要途径。在国外,甲苯歧化法已工业化。但所用的催化剂都十分保密。遵照伟大领袖毛主席“独立自主,自力更生”的教导,我们开展了甲苯歧化催化剂的研究工作。近年来,国内有些单位对甲苯歧化催化剂也做了大量的研究工作,上海石油化学所

With the rapid development of China’s socialist construction and the ever-increasing standard of living of the people, the demand for benzene and xylene, the three major raw materials for synthetic materials, especially synthetic fibers, has rapidly increased. Therefore, using toluene disproportionation method to convert a large amount of toluene from petroleum refining into benzene and xylene is an important way to solve the imbalance between supply and demand of triphenylbenzene. Abroad, toluene disproportionation has been industrialized. However, the catalyst used is very confidential. Following the teachings of the great leader Chairman Mao, “Independent, Self-reliance,” we conducted a research project on toluene disproportionation catalysts. In recent years, some domestic units of toluene disproportionation catalyst also made a lot of research work, Shanghai Petrochemical
