The process is characterized in that a porous molecular sieve catalyst consisting of a product obtained by evaporating water from a raw material mixture comprising a molecular sieve with a framework of Si—OH—Al— groups, a water-insoluble metal salt, and ... 09/14/06 - 20060205989 - Autothermal cracking process The present invention provides a process for the production of olefins which process comprises co-feeding at least one unsaturated hydrocarbon with a paraffinic hydrocarbon-containing feedstock and a molecular oxygen-containing gas to an autothermal cracker, wherein they are reacted in the presence of a catalyst capable of supporting combustion beyond the ... 05/11/06 - 20060100473 - Production of olefins A process for steam cracking a hydrocarbon feedstock containing olefins to provide increased light olefins in the steam cracked effluent, the process comprising passing a first hydrocarbon feedstock containing one or more olefins through a reactor containing a crystalline silicate to produce an intermediate effluent with an olefin content of ... 10/20/05 - 20050234282 - Method for production propylene from a flow containing c4 to c8 olefins In a method for the production of propylene, a charge stream containing C4 to C6 olefins is evaporated, superheated, mixed with hot water vapor, the olefins vapor mixture converted on a zeolite catalyst, the reaction mixture formed thereby cooled, and then partially condensed. In order to increase the yield of ... 07/07/05 - 20050148806 - Method for the preparation of lower olefines by steam cracking A method for the preparation of lower olefins by steam cracking, wherein the feed containing heavy hydrocarbons obtained by Fischer-Tropsch synthesis is subjected to steam cracking in a naphtha designed steam cracking furnace for steam cracking the Fischer-Tropsch hydrocarbons into the lower olefins. ... 06/16/05 - 20050131263 - Process and finned tube for the thermal cracking of hydrocarbons In a process for the thermal cracking of hydrocarbons in the presence of steam, the charge mixture is passed through externally heated tubes with helical inner fins, and to make the temperature in the tube wall and over the tube cross section more uniform, as well as to reduce the ... ### FreshPatents.com Support |
