20080255399Method for Production of Diphenylethylene - The invention relates to a method for production of diphenylethylene (DPE) comprising the steps of: (a) catalytic dehydrogenation of diphenylethane (DPA) in the presence of water, (b) addition of a light organic solvent to the mixture from step (a) and (c) decanting the mixture from step (b) with recovery of a flow comprising diphenylethylene as a mixture with the solvent added in step (b). The invention further relates to a given mixture of DPE, DPA and solvent and use thereof in polymerisation.10-16-2008
20080312483Process for Producing Aromatic Hydrocarbon and Hydrogen - A process for producing aromatic hydrocarbons and hydrogen, in which a lower hydrocarbons-containing feedstock gas is reformed by being supplied to and being brought into contact with a catalyst under high temperature conditions thereby forming aromatic hydrocarbons and hydrogen. The method includes the steps of (a) supplying a hydrogen gas together with the feedstock gas during a supply of the feedstock gas; and (b) suspending the supply of the feedstock gas for a certain period of time while keeping a condition of a supply of the hydrogen gas. The catalyst is exemplified by a metallo-silicate carrying molybdenum and a metallo-silicate carrying molybdenum and rhodium. An amount of the hydrogen gas supplied together with the feedstock gas is set to be preferably larger than 2% and smaller than 10%, more preferably within a range of from 4 to 8%, much more preferably 8%. As a pretreatment for a reforming reaction by which aromatic hydrocarbons and hydrogen are formed, the catalyst is increased in temperature and kept at the temperature for a certain period of time while a gas containing methane and hydrogen is supplied thereto.12-18-2008
