  • Patent number: 7022637
    Abstract: 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.

  • Patent number: 6451729
    Abstract: The present invention is a new and simple method of decomposing ammonium tetrathiomolybdate (ATTM) in an organic solvent with added water under H2 pressure. Model compound reactions of 4-(1-naphthylmethyl)bibenzyl (NMBB) were carried out at 350-425° C. under H2 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° 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° C. under H2 pressure by hot purging gives highly active Mo sulfide catalyst.

  • Patent number: 5523505
    Abstract: 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.
