Chemistry Of Hydrocarbon Compounds > Unsaturated Compound Synthesis > By Double-bond-shift Isomerization By Double-bond-shift IsomerizationBy Double-bond-shift Isomerization 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.10/19/06 - 20060235255 - Double bond hydroisomerization process A process and apparatus are disclosed for hydroisomerizing a mixed C4 olefin stream in a catalytic distillation column in order to increase the concentration of 2-butene and minimize the concentration of 1-butene, while concurrently minimizing the production of butanes. In one embodiment, carbon monoxide is introduced into the double bond ... 10/19/06 - 20060235254 - Double bond hydroisomerization process A process and apparatus are disclosed for hydroisomerizing a mixed C4 olefin stream in a fixed bed hydroisomerization reactor in order to increase the concentration of 2-butene and minimize the concentration of 1-butene, while concurrently minimizing the production of butanes. In one embodiment, carbon monoxide is introduced into the double ... 10/19/06 - 20060235253 - Process for the double bond hydroisomerization of butenes A process is disclosed for the preferential conversion to 2-butene of a stream containing C4 compounds including 1-butene and 2-butene. The process involves mixing the C4 stream with a first hydrogen stream to form a feed stream, hydroisomerizing the feed stream in the presence of a first hydroisomerization catalyst in ... 10/19/06 - 20060235252 - Double bond hydroisomerization of butenes A process is disclosed for the preferential conversion to 2-butene of a C4 stream containing 1-butene and 2-butene. The process involves mixing the C4 stream with a first hydrogen stream to form a feed stream, hydroisomerizing the feed stream in the presence of a first hydroisomerization catalyst in order to ... 08/17/06 - 20060183954 - Process for the isomerization of an olefin A process for the double bond isomerization of an olefin, which process comprises contacting a feed comprising the olefin with an isomerization catalyst, wherein prior to contacting the feed with the isomerization catalyst one or more components of the feed are pretreated by contacting with a pretreating material which comprises ... 07/20/06 - 20060161037 - Catalyst composition comprising a heteropoly acid, zinc, and a support component and processes therefor and therewith A process of contacting at least one isoparaffin and at least one C5 olefin in the presence of a catalyst composition under conversion conditions to provide for converting the at least one isoparaffin and the at least one C5 olefin is provided. The catalyst composition contains a heteropoly acid, zinc, ... 06/15/06 - 20060129013 - Specific functionalization and scission of linear hydrocarbon chains The present invention relates generally to a method of producing single carbon number olefins and/or a narrow distribution of olefin products on demand and not as part of a distribution. The invention also relates to the olefins so produced, including, by way of example, 1-octene, and Cn-olefins. More specifically, in ... ### FreshPatents.com Support |
