    摘要： The present invention is a new and simple method of decomposing ammonium tetrathiomolybdate (ATTM) in an organic solvent with added water under H.sub.2 pressure. Model compound reactions of 4-(1-naphthylmethyl)bibenzyl (NMBB) were carried out at 350-425.degree. C. under H.sub.2 pressure in order to examine the activity of the Mo sulfide catalysts generated from ATTM with and without added water for C--C bond cleavage and hydrogenation of aromatic ring. The Mo sulfide catalysts generated from ATTM with added water were much more effective for C--C bond cleavage and hydrogenation of aromatic moieties at 350-425.degree. C. than those from ATTM alone. Two-step tests revealed that the addition of water is effective for generating highly active Mo sulfide catalyst from ATTM, but water itself does not promote catalytic conversion. Removal of water after the decomposition of ATTM with added water at 350-400.degree. C. under H.sub.2 pressure by hot purging gives highly active Mo sulfide catalyst.

    摘要翻译： 本发明是一种在H2压力下加入水分解有机溶剂中四硫代钼酸铵（ATTM）的新型简单方法。 在氢气压力下，在350-425℃下进行4-（1-萘基甲基）联苄（NMBB）的模型化合物反应，以便检测由ATTM生成的硫化钼催化剂的活性，并且不加入水分用于CC键 芳环的裂解和氢化。 由ATTM生成的添加水的Mo硫化物催化剂在350-425℃比单独的ATTM对C-C键断裂和芳烃部分氢化更有效。 两步测试表明，添加水对于从ATTM产生高活性的硫化钼催化剂是有效的，但是水本身不能促进催化转化。 在氢气压力下通过热吹扫在350-400℃加入ATTM分解后除去水，得到高活性的硫化钼催化剂。

    摘要： An environmentally benign catalytic process for the production of sym-octahydroanthracene (sym-OHA) from sym-octahydrophenanthrene (sym-OHP) by ring-shift isomerization. Proton-form moralenite or partially dealuminated proton-form mordenite are effective catalysts for the selective formation of sym-OHA from sym-OHP. Y-zeolite and metal-ion exchanged Y-zeolites display lower selectivity towards Sym-OHA. The use of certain solvents can further improve the performance of the Y-zeolites and mordenites, particularly the selectivity of Y-zeolite catalysts. The sym-OHA is an useful product and can be converted by existing methods to various anthracene derivatives which are industrial chemicals in demand.

    摘要： Novel catalysts and processes in accordance with the invention can accomplish high selectivity and conversion of naphthalenic compounds such as the conversion of methylnaphthalene (2-MN) or naphthalene to 2,6-dimethylnaphthalene (2,6-DMN). The catalysts are prepared by treating, for example, a ZSM-5-type material with iron in the presence of a halogen such as a fluoride. The resulting catalyst includes iron, as well as a significant portion of aluminum present in the ZSM-5-type starting material. Processes for using the catalysts also are disclosed.
