  • Heat recovery in an olefin production process
    Patent number: 6870072
    Abstract: Disclosed is a process for recovering heat in an oxygenate to olefin (“OTO”) production process. The process includes removing heat while maintaining the temperature of an effluent stream that comprises solid particles (typically catalyst particles) and a gas phase comprising prime olefins from an OTO reactor above the dew point temperature of the effluent stream. The process further includes washing the effluent stream in solids wash to remove the solid particles from the gas phase into a liquid wash medium.
    Type: Grant

    Date of Patent: March 22, 2005
    Assignee: ExxonMobil Chemical Patents Inc.

  • Process for handling catalyst from an oxygenate to olefin reaction
    Publication number: 20040064006
    Abstract: The present invention is a process for removing catalyst fines from an effluent stream in an oxygenate to olefin process. Specifically, the catalyst fines in the effluent stream are separated from the effluent stream. Then the carbonaceous deposits are removed from the catalyst fines by incineration.

  • Conversion process
    Publication number: 20040034265
    Abstract: The invention relates to a conversion process for making olefin(s) using a molecular sieve catalyst composition. More specifically, the invention is directed to a process for converting a feedstock comprising an oxygenate in the presence of a molecular sieve catalyst composition, wherein the feedstock is free of or substantially free of metal salts.
