    摘要： A method for converting heavy olefins present in a product stream exiting a first reaction zone into light olefins and carbonaceous deposits on a catalyst without separation of the heavy olefins from the product stream exiting the first reaction zone. The method comprises creating the product stream exiting the first reaction zone, the product stream exiting the first reaction zone comprising the heavy olefins, moving the product stream exiting the first reaction zone to a second reaction zone without separation of the heavy olefins from the product stream exiting the first reaction zone, and contacting the product stream exiting the first reaction zone with the catalyst under conditions effective to form the light olefins, the contacting causing the carbonaceous deposits to form on at least a portion of the catalyst.

    摘要： The present invention provides a method for maintaining temperature during regeneration of an oxygenate to olefins catalyst using liquid water as a coolant in an amount sufficient either to reduce duty of a catalyst cooler or to avoid the need to use a catalyst cooler altogether. The method also may be used to hydrotreat fresh, non-hydrothermally treated catalyst which may be added to the regenerator and charged back to the conversion reactor along with the regenerated catalyst.

    摘要： A process for the separation and removal, of hydrogen, alone or together with carbon monoxide, if present, from a mixture of these gases with reactive unsaturated hydrocarbons, by contacting the mixture with oxygen over a catalyst at conditions sufficient to oxidize the hydrogen to form water while suppressing reaction of the reactive, unsaturated hydrocarbons. The catalyst contains at least one metal or metal oxide from Groups IB, IIB, IIIB, IVB, VB, VIB, VIIB, and VIII of the Periodic Table, and the temperature of the reaction may range from about 40.degree. C. to about 300.degree. C., the pressure of the reaction ranges from about 14.7 psig to 1,000 psig, and the flow rate of the entering feed ranges from about 1 GHSV to about 50,000 GHSV. Oxygen amounts less than the stoichiometric amount required to react with the hydrogen, and optionally any carbon monoxide, are used. In a second stage, any remaining carbon monoxide is reacted with water in a water gas-shift reaction to give carbon dioxide and hydrogen, and any small remaining hydrogen is reacted with a small portion of reactive unsaturated hydrocarbon present.
