  • Publication number: 20140318944
    Abstract: Disclosed in one embodiment is a method for the catalytic pyrolysis of a carbonaceous material that includes contacting the carbonaceous material with a plurality of catalyst particles to produce a gas phase product and a solid phase product and separating the gas phase product from the solid phase product and the plurality of catalyst particles. The method further includes partially regenerating the plurality of catalyst particles by exposing the solid phase product and the catalyst particles to a first oxidizing condition to produce an oxidized solid phase and a partially-regenerated catalyst and cooling the partially-regenerated catalyst and a non-oxidized portion of the solid phase product. Still further, the method includes further regenerating the partially-regenerated catalyst by exposing the non-oxidized portion of the solid phase product and the partially-regenerated catalyst to a second oxidizing condition.

  • Publication number: 20090238752
    Abstract: A process for controlling a refinery or chemical process has been developed. The process comprises flowing a feed stream to a process unit; operating on the feed stream in the process unit to generate an effluent stream; flowing the effluent stream away from the process unit; passing at least a portion of the feed stream or the effluent stream through a catalytic alloy hydrogen sensor and generating a signal corresponding to the concentration of hydrogen present in either the feed stream or the effluent stream; passing the signal to a display unit; and adjusting at least one operating parameter of the process in response to at least the signal generated by the catalytic alloy hydrogen sensor. The catalytic alloy hydrogen sensor may be a palladium-nickel catalytic alloy hydrogen sensor. The adjustments may be based on a calculated mole percent hydrogen.

  • Publication number: 20090126566
    Abstract: The invention discloses the use of polymer functionalized molecular sieve/polymer mixed matrix membranes (MMMs) with either no macrovoids or voids of less than several Angstroms at the interface of the polymer matrix and the molecular sieves by incorporating polyethersulfone (PES) or cellulose triacetate (CTA) functionalized molecular sieves into a continuous polyimide or cellulose acetate (CA) polymer matrix. The MMMs, particularly PES functionalized AlPO-14/polyimide MMMs and CTA functionalized AlPO-14/CA MMMs, in the form of symmetric dense film, asymmetric flat sheet membrane, or asymmetric hollow fiber have good flexibility and high mechanical strength, and exhibit significantly enhanced selectivity and/or permeability over the polymer membranes made from the corresponding continuous polymer matrices for carbon dioxide/methane (CO2/CH4), hydrogen/methane (H2/CH4), propylene/propane separations and a variety of liquid, gas, and vapor separations.

  • Publication number: 20080153174
    Abstract: A process for sensing hydrogen in a refinery process stream or a chemical process stream has been developed. The process comprises flowing at least a portion of the refinery process stream or the chemical process stream through a conduit which is part of a main support and through a series of flow components which are attached to the main support and in fluid communication with the conduit. The flow components comprise, a needle valve, a pressure indicator, a catalytic alloy hydrogen sensor, and a back pressure regulator. The catalytic alloy hydrogen sensor may be a palladium-nickel catalytic alloy hydrogen sensor. The process continues with generating a signal indicating the amount of hydrogen in the stream using the catalytic alloy hydrogen sensor and communicating the signal to a display device or a computer processor. The process may further include adjusting an operating parameter based upon the signal indicating the amount of hydrogen in the stream, or based upon a calculated mole percent hydrogen.
