  • Patent number: 7435598
    Abstract: An apparatus and process are described in which a plurality of preloaded catalyst samples tubes can be serially and automatically moved from a support to a reaction zone where each catalyst sample can be heated and a preheated reagent feed contacted with the sample and the effluent fed to a product collection and analysis system.

  • Patent number: 7256052
    Abstract: This invention is to a microreactor type of reaction and analysis system. The system includes a chemical reaction chamber having internal conduits through which a chemical reactant, such as a reaction gas, can be fed. The conduits for transporting fluids such as reactant, carrier gas and balance gas are in appropriate communication such that the amount of reactant going directly to a catalyst located in the reaction chamber can be optimally controlled. The system is highly useful for studying the kinetics of a chemical reaction.

  • Patent number: 7151199
    Abstract: Hydrocarbon or oxygenate conversion process in which a feedstock is contacted with a non zeolitic molecular sieve which has been treated to remove most, if not all, of the halogen contained in the catalyst. The halogen may be removed by one of several methods. One method includes heating the catalyst in a low moisture environment, followed by contacting the heated catalyst with air and/or steam. Another method includes steam-treating the catalyst at a temperature from 400° C. to 1000° C. The hydrocarbon or oxygenate conversion processes include the conversion of oxygenates to olefins, the conversion of oxygenates and ammonia to alkylamines, the conversion of oxygenates and aromatic compounds to alkylated aromatic compounds, cracking and dewaxing.

  • Patent number: 6440894
    Abstract: Methods of calcining non-zeolitic molecular sieve catalyst to remove most, if not nearly all, of halogen contained in the catalyst. One method includes heating the catalyst in a low moisture environment, followed by contacting the heated catalyst with air and/or steam. Another method includes steam-treating the catalyst at a temperature from 400° C. to 1000° C. The calcination methods provides a catalyst that contains from about 10 ppmw to about 600 ppmw chlorine, preferably 10 ppmw to about 200 ppmw chlorine, more preferably 10 ppmw to about 80 ppmw chlorine.
