  • Publication number: 20150152026
    Abstract: A method for the oxidative coupling of hydrocarbons includes providing an oxidative catalyst inside a reactor and carrying out the oxidative coupling reaction under a set of reaction conditions. The reactor surfaces that contact the reactants and products do not provide a significant detrimental catalyzing effect. In an embodiment the reactor contains an inert lining or a portion of the reactor inner surface is treated to reduce the detrimental catalytic effects. In an embodiment the reactor contains a lining that includes an oxidative catalyst.

  • Patent number: 8969642
    Abstract: A process for making styrene is disclosed that includes reacting toluene with a C1 source and a co-feed in the presence of a catalyst in a reactor to form a first product stream comprising styrene, ethylbenzene, carbon monoxide, and hydrogen; separating the hydrogen and carbon monoxide from the first product stream to form a second stream; separating the hydrogen from the second stream to form a third stream comprising hydrogen and a fourth stream comprising carbon monoxide; wherein the fourth stream is recycled to the reactor and forms at least a portion of the co-feed.
