Chemistry Of Hydrocarbon Compounds > Unsaturated Compound Synthesis > From Nonhydrocarbon Feed > Alcohol, Ester, Or Ether > Using Metal Oxide Catalyst Using Metal Oxide CatalystUsing Metal Oxide Catalyst patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.06/22/06 - 20060135836 - Processes for lifting spent catalyst into a regenerator in an oxygenate to olefins reaction system This invention provides processes for transporting catalyst, preferably in an oxygenate to olefins reaction system. In one embodiment, an oxygenate contacts molecular sieve catalyst particles in a reactor under conditions effective to form an effluent stream comprising light olefins and forming coked catalyst particles. At least a portion of the ... 06/22/06 - 20060135835 - Method and system for catalytically converting oxygenates and regenerating and stripping catalyst A method of converting oxygenate-containing feedstock to light olefins comprises charging a reactor with catalyst, feeding the feedstock into the reactor, contacting the feedstock with the catalyst and converting the feedstock to olefins while depositing byproducts on catalyst resulting in spent catalyst, regenerating the spent catalyst by combustion gases, and ... 05/11/06 - 20060100472 - Method of synthesizing silicoaluminophosphate molecular sieves In a method of synthesizing a silicoaluminophosphate molecular sieve, a synthesis mixture is prepared by combining a source of phosphorus and at least one organic directing agent; and then introducing a source of aluminum into the combination of the phosphorus source and organic directing agent, wherein the temperature of the ... 04/06/06 - 20060074267 - Aluminophosphate molecular sieve, its synthesis and use A large pore (metallo)aluminophosphate molecular sieve is disclosed The material has an X-ray diffraction pattern including the lines listed in Table 4 and is synthesized in the presence of 4-dimethylaminopyridine as structure directing agent. ... 11/03/05 - 20050245781 - Fines co-feed for maintaining efficient reactor hydrodynamics This invention provides processes for maintaining a desired particle size distribution in an oxygenate to olefin reaction system. In one embodiment, the invention comprises replacing lost catalyst fines with less active co-catalyst particles. By adding less active co-catalyst particles to the reaction system, desirable fluidization characteristics and hydrodynamics can be ... 09/15/05 - 20050203326 - Process for containment of catalyst particles in a oxygenate-to-olefin process The present invention provides a process and apparatus for removing catalyst fines from a reactor effluent stream withdrawn from an oxygenate conversion reactor. This process comprises exposing a hydrocarbon stream to a catalyst within an oxygenate conversion reactor to produce a reactor effluent stream, wherein said reactor effluent stream contains ... 09/08/05 - 20050197520 - Chabazite-type molecular sieve, its synthesis and its use in the conversion of oxygenates to olefins The synthesis of a crystalline material, in particular a high silica zeolite, having a chabazite-type framework is aided by the addition to the synthesis mixture of seeds of an AEI framework-type material. The chabazite-type product has a relatively small crystal size and exhibits activity and selectivity in the conversion of ... 09/08/05 - 20050197519 - Aei-type zeolite, its synthesis and its use in the conversion of oxygenates to olefins wherein X is a trivalent element, Y is a tetravalent element n is from 0 to less than 0.01. The material is normally synthesized in a halide, typically a fluoride, medium and exhibits activity and selectivity in the conversion of methanol to lower olefins, especially ethylene and propylene. ... 08/04/05 - 20050171394 - Method for in-situ synthesis of crystalline microporous metalloaluminophosphate in a formed body The invention concerns a method for production of microporous crystalline metalloaluminiumphosphates (ELAPO) based adsorbents or catalysts by in-situ crystallisation of ELAPO inside a formed body. First the formed body containing aluminium phosphate (AlPO) and binder is prepared, thereafter the organic structure directing agent, EL source and water are added and ... 06/09/05 - 20050124838 - Catalyst fluidization in oxygenate to olefin reaction systems The present invention provides various processes for fluidizing molecular sieve catalyst compositions in a fluidized bed reaction system. The invention comprises fluidizing a molecular sieve catalyst composition with a reactive fluidizing medium under conditions effective to convert at least a portion of the fluidizing medium to additional product. The invention ... ### FreshPatents.com Support |
