| 20090216057 | Method for Preparing Linear Alpha-Olefins - The present invention relates to a method for preparing linear alpha-olefins by oligomerizing of ethylene in the presence of an organic solvent and a homogenous catalyst, characterized in that the method is carried out in a reactor being fed with a gaseous feed comprising a minor amount of ethylene and a major amount of an inert gas. | 08-27-2009 |
| 20090221769 | Method for the preparation of linera alpha-olefins and reactor system therefor with improved disposal of high molecular weight oligomers - The present invention relates to a method for processing high molecular weight oligomer waste products formed during the production of linear alpha-olefins by oligomerization of ethylene in a reactor in the presence of a solvent and a catalyst, characterized in that the high molecular weight oligomers are separated in a separation unit from a product stream of the reactor comprising the solvent, the catalyst, linear alpha-olefins and high molecular weight oligomers having a solidification temperature in the range of about 60-100° C., then diluted with a dilution medium and heated to about 130° C. to about 200° C., the diluted high molecular weight oligomers are then transferred to a disposal device, wherein at least some of the dilution medium may be recovered and recycled for addition to the dilution medium. | 09-03-2009 |
| 20090247714 | PROCESS AND PLANT FOR OLIGOMERIZATION/POLYMERIZATION OF ETHYLENE AND/OR ALPHAOLEFINS - The present invention relates to a process for oligomerization/polymerization of ethylene and/or alpha-olefins, comprising the steps of oligomerizing/polymerizing ethylene and/or alpha-olefins to produce a reaction product which contains undesired reaction by-products, separating the reaction by-product from the reaction product as one or more reaction by-product fractions, and subjecting at least one of the reaction by-product fractions to steam cracking to produce a steam cracking product which comprises ethylene, which may be optionally purified and feed to the oligomerization/polymerization of ethylene and/or alpha olefins step. | 10-01-2009 |
| 20090306312 | Method for Preparing Linear Alpha-Olefins With Improved Heat Removal - The present invention relates to a method for preparing linear alpha-olefins by oligomerizing of ethylene in the presence of a first organic solvent and a homogenous catalyst in a reactor, characterized in that the reactor overhead is cooled by means of a refrigerant. | 12-10-2009 |
| 20090314986 | Method for Deactivation of an Organometallic Catalyst and Reactor System Therefor - The present invention relates to a method for the deactivation of an organometallic catalyst in the product stream from an oligomerization reactor for the production of linear alpha-olefin, characterized in that the catalyst-containing product stream of the reactor is subjected to a temperature of at least 160° C. in a heating device. A reactor system for the method of the invention is also disclosed. | 12-24-2009 |
| 20100206334 | Method for cleaning a reactor - The present invention relates to a method for cleaning a reactor having a tendency of fouling by deposition of solids, wherein a hot solvent, in which the solids are soluble and which has a temperature of at least about 75° C., is applied to the reactor, the solids being substantially dissolved and the dissolved solids being discharged from the reactor, wherein the method is carried out without opening the reactor to atmosphere. | 08-19-2010 |
