  • Stabilizing catalyst activity during catalyst regeneration
    Patent number: 7619128
    Abstract: This invention is directed to methods of converting oxygenates to olefin products. The methods provided include steps for protecting against deactivation of active molecular sieve catalysts during the conversion process. In particular, the invention provides for methods of regenerating coked catalyst to minimize catalyst deactivation due to contact with moisture.

  • Controlling solids flow in a gas-solids reactor
    Patent number: 7220341
    Abstract: This invention is to a process and system for controlling solids distribution in a gas-solids reactor. Solids distribution is controlled by controlling electrical charges between solid particles flowing between conductive surfaces within a gas-solids reactor. The electrical charges are controlled by conventional means such as by grounding the opposing conductive surfaces, or by applying a voltage to one of the opposing conductive surfaces.
