| 585664000 | By double-bond-shift isomerization | 6 |
| 585665000 | Using organometallic catalyst | 1 |
| 20090030255 | PROCESS FOR PRODUCING UNSATURATED HYDROCARBON COMPOUND - Disclosed is a method for producing an unsaturated hydrocarbon compound wherein an α-olefin is dimerized by using a catalyst system composed of a metallocene compound (A) and an oxygen-containing organometallic compound modified with a halogen-containing compound (B). By this method, an unsaturated hydrocarbon compound having unsaturated double bonds in a high ratio, in particular the one having a terminal vinylidene group can be produced efficiently. | 01-29-2009 |

| 20110021858 | CATALYST FOR METATHESIS OF ETHYLENE AND 2-BUTENE AND/OR DOUBLE BOND ISOMERIZATION - A process for the double-bond isomerization of olefins is disclosed. The process may include contacting a fluid stream comprising olefins with a fixed bed comprising an activated basic metal oxide isomerization catalyst to convert at least a portion of the olefin to its isomer. The isomerization catalysts disclosed herein may have a reduced cycle to cycle deactivation as compared to conventional catalysts, thus maintaining higher activity over the complete catalyst life cycle. | 01-27-2011 |
| 20110077444 | Metathesis Catalyst for Olefin Production - A catalyst includes a metathesis catalyst and an isomerization catalyst. In one embodiment, WO | 03-31-2011 |
| 20120016172 | METHOD FOR MANUFACTURING OLEFIN - A method for manufacturing an olefin through reaction between the same type of or different types of raw material olefins to obtain an olefin having a structure different from the structure of the raw material olefins, the method including using a catalyst containing at least one type of metal element selected from the group consisting of tungsten, molybdenum, and rhenium together with other specific catalysts. In the method, side reactions of a metathesis reaction can be suppressed and the selectivity of a desired product can be increased by facilitating double bond isomerization of raw material olefins. Furthermore, the desired product can be obtained efficiently at a high productivity by maintaining the activity of a metathesis catalyst for a long term and suppressing deterioration of performance of a catalyst (isomerization catalyst) for facilitating double bond isomerization of the raw material olefins. | 01-19-2012 |
| 20140066681 | CATALYST FOR METATHESIS OF ETHYLENE AND 2-BUTENE AND/OR DOUBLE BOND ISOMERIZATION - A process for the double-bond isomerization of olefins is disclosed. The process may include contacting a fluid stream comprising olefins with a fixed bed comprising an activated basic metal oxide isomerization catalyst to convert at least a portion of the olefin to its isomer. The isomerization catalysts disclosed herein may have a reduced cycle to cycle deactivation as compared to conventional catalysts, thus maintaining higher activity over the complete catalyst life cycle. | 03-06-2014 |
