Abstract: The present invention relates to a process for the preparation of synthesis gas (i.e., a mixture of carbon monoxide and hydrogen), typically labeled syngas. More particularly, the present invention relates to a regeneration method for a syngas catalyst. Still more particularly, the present invention relates to the regeneration of syngas catalysts using a re-dispersion technique. One embodiment of the re-dispersion technique involves the treatment of a deactivated syngas catalyst with a re-dispersing gas, preferably a carbon monoxide-containing gas such as syngas. If necessary, the catalyst is then exposed to hydrogen for reduction and further re-dispersion.

Abstract: 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.

Abstract: This invention relates to a process for regeneration of a zeolite catalyst, specifically an aluminosilicate zeolite with germanium substituted in the framework for silicon and with platinum deposited on the zeolite. The catalyst may be used in a process for aromatization of alkanes, specifically C2-C8 alkanes. The regeneration process 1) removes coke and sulfur from the catalyst via oxidation, 2) redisperses platinum on the surface of the catalyst via chlorine gas, 3) removes chlorine and bind Pt to the surface of the zeolite by steaming, 4) reduces the catalyst in hydrogen, and 5) optionally, resulfides the catalyst. The zeolite may be a MFI zeolite. The catalyst may be bound with an inert material which does not act as a binding site for platinum during the regeneration process, for example, silica.

Abstract: Methods and apparatus for providing the heat required to maintain the desired temperature for catalyst regeneration. The catalyst is heated by contacting a reactant gas mixture with the catalyst in order to initiate an exothermic reaction and, once the desired temperature is achieved, exposing the catalyst to a regenerating gas. The temperature may also be maintained by heating the reactant gas mixture prior to contacting the catalyst and/or adding a liquid, which may be heated, to the catalyst. For heating a Fischer-Tropsch catalyst for regeneration, the reactant gas preferably contains less than 12 mole percent carbon monoxide and more preferably contains between 1 and 4 mole percent carbon monoxide.
