Chemistry Of Hydrocarbon Compounds > Unsaturated Compound Synthesis > By C Content Reduction, E.g., Cracking, Etc. > Using Catalyst Using CatalystUsing 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.01/04/07 - 20070004953 - Protection of solid acid catalysts from damage by volatile species The invention provides a method to avoid catalyst damage and achieve longer catalyst life by selecting appropriate materials for reactor spacers, liners, catalyst binders, and supports, in particular, by not using crystalline silica-containing and high phosphorus-containing materials, if the presence of even small amount of steam is anticipated. In addition, ... 06/01/06 - 20060116544 - Process for producing olefin by catalytic cracking of hydrocarbon A process for producing olefin by catalytic cracking of hydrocarbon material characterized in employing zeolite of penta-sil type comprising rare earth elements and at least one of manganese or zirconium as a catalyst. It enables to produce light olefin such as ethylene, propylene, and so on with selectively high yield ... 04/06/06 - 20060074268 - Process for the production of olefins A process for the production of an olefin from a hydrocarbon, which process comprises: partially combusting the hydrocarbon and an oxygen-containing gas in the presence of a catalyst, characterised in that the catalyst comprises palladium and at least one further metal, said further metal being a Group IIIA, Group IVA, ... 03/23/06 - 20060063957 - Moving bed process for producing propylene, recycling a fraction of used catalyst The invention concerns a process for producing propylene from a steam cracking and/or catalytic cracking light olefinic cut, said process comprising a moving bed catalytic cracking step with a catalyst regeneration loop. The process recycles a portion of the used catalyst to the inlet of the moving bed reactor. The ... 03/16/06 - 20060058563 - Hydrocarbon steam cracking catalyst for olefin preparation, method for preparing the same, and olefin preparation method using the same The present invention relates to a catalyst for steam cracking of hydrocarbons, which steam cracks hydrocarbons to improve a yield of olefins such as ethylene and propylene, reduces produced coke, and has superior thermal stability at a high temperature. Particularly, the present invention provides a catalyst for steam cracking of ... ### FreshPatents.com Support |
