  • Publication number: 20150175898
    Abstract: Methods for organic compound conversion are disclosed. Particular methods include providing a first mixture comprising ?10.0 wt % of at least one oxygenate, based on the weight of the first mixture; contacting said first mixture in at least a first moving bed reactor with a catalyst under conditions effective to covert at least a portion of the first mixture to a product stream comprising water, hydrogen, and one or more hydrocarbons; and separating from said product stream (i) at least one light stream and ii) at least one heavy stream, wherein the method is characterized by a recycle ratio of ?5.0.

  • Patent number: 8618010
    Abstract: The present invention relates to new processes for regenerating oxidized interstitial metal hydride containing catalysts prior to the use of such catalysts in a hydroprocessing process. Interstitial metal hydride containing catalysts are easily oxidized in the environment and once oxidized, the hydroprocessing activity of the interstitial metal hydrides is most often severely diminished and this lost activity due to oxidization of the iMeH is not susceptible to recovery under hydroprocessing conditions. As a result, these catalysts in the present art require considerable special handling in inert environments all through processes from fabrication, shipping, loading, use, and maintenance of the catalyst systems to protect the activity of the interstitial metal hydride components.

  • Patent number: 8536085
    Abstract: A method is provided for preparing a supported cobalt-containing catalyst having substantially homogeneously dispersed, small cobalt crystallites. The method comprises depositing cobalt nitrate on a support and then subjecting the support to a two-step decomposition protocol. In the first step, the support is heated in an oxygen-containing, substantially water-free atmosphere to about 160° C. to form an intermediate decomposition product. This intermediate product is then or hydrolyzed and reduced, or hydrolyzed, calcined and reduced.

  • Publication number: 20110119992
    Abstract: The present invention relates to novel interstitial metal hydrides and catalyst containing interstitial metal hydrides that are resistant to oxidation and resultant loss of catalytic activity. The processes of the present invention include use of these improved, oxidation resistant interstitial metal hydride compositions for improved overall hydrogenation, product conversion, as well as sulfur reduction in hydrocarbon feedstreams.
