Abstract: A process for the conversion of methanol to olefins includes the steps of passing a feedstock comprising methanol to a fluidized bed reactor in contact with a catalyst to produce an olefin product, wherein the process at least partially deactivates the catalyst to form an at least partially deactivated catalyst; and passing spent catalyst from said at least partially deactivated catalyst to a regenerator for regeneration thereby forming regenerated catalyst and returning activated catalyst from said regenerated catalyst to said reactor via a regenerated catalyst line. An oxygen volume content in the gas-phase component at the outlet of the regenerated catalyst pipeline is controlled to be less than 0.1 percent, preferably less than 0.05% and more preferably less than 0.01% on the regenerated catalyst pipeline.

Abstract: Polyethers are prepared by polymerizing an alkylene oxide in the presence of a double metal cyanide catalyst complex and certain M5 metal or semi-metal compounds. The double metal cyanide catalyst complex contains 0.5 to 2 weight percent potassium. The ability of this catalyst system to tolerate such high amounts of potassium permits the catalyst preparation procedure to be simplified and less expensive.

Abstract: The present invention relates to a process for direct production of mixtures of short-chain high-functionality polyoxyalkylene polyols and long-chain low-functionality polyoxyalkylene polyols. The short-chain high-functionality polyoxyalkylene polyol component is obtained by alkylene oxide addition onto high-functionality H-functional starter compounds while the long-chain low-functionality polyoxyalkylene polyol component is correspondingly obtained by alkylene oxide addition onto low-functionality H-functional starter compounds. The invention further relates to the resulting polyoxyalkylene polyols and to the reaction thereof to produce polyurethanes.

Abstract: Disclosed are to a supported catalyst used for synthesizing polyether amine, and a preparation method and use thereof. The supported catalyst introduces Mo and CeO2 into Ni and Cu active components. By means of the cooperation of Ni, Cu and Mo, CeO2 and Ni form more active sites, such that the supported catalyst can have high reaction activity and selectivity. By using the supported catalyst to synthesize polyether amine, the amination efficiency and selectivity of polyether polyol can be greatly enhanced, thereby preparing the polyether amine with light color and narrow molecular weight distribution. In addition, the cost of the catalyst can be reduced, a process condition is relatively mild, and the disadvantage of low reaction activity of a nickel-based catalyst in synthesizing small molecule polyether amine can be overcome, such that the supported catalyst has a desirable industrial application prospect.
