| 20080242908 | Recycle Of DME In An Oxygenate-To-Olefin Reaction System - This invention is directed to a process for producing one or more olefins from an oxygenate feed. According to the invention, an oxygenate stream is provided and a recycle stream is added to the oxygenate stream to form a feed stream to an oxygenate-to-olefin conversion system. The recycle stream comprises (i.e., contains) propane and dimethyl ether. | 10-02-2008 |
| 20100063338 | Process for feeding ethylene to polymerization reactors - Provided are processes for feeding ethylene into a polymerization system operating in a liquid phase or supercritical phase. The process includes providing a low-pressure ethylene stream, one or more low-pressure C | 03-11-2010 |
| 20100249480 | Process for Oligomerizing Dilute Ethylene - The process and apparatus converts ethylene in a dilute ethylene stream that may be derived from an FCC product to heavier hydrocarbons. The catalyst may be an amorphous silica-alumina base with a Group VIII and/or VIB metal. The catalyst is resistant to feed impurities such as hydrogen sulfide, carbon oxides, hydrogen and ammonia. At least 40 wt-% of the ethylene in the dilute ethylene stream can be converted to heavier hydrocarbons. | 09-30-2010 |
| 20110245567 | PROCESS FOR OLIGOMERIZING DILUTE ETHYLENE - The process converts ethylene in a dilute ethylene stream that may be derived from an FCC product to heavier hydrocarbons. The oligomerization reactor is in communication between a primary absorber column and a secondary absorber column in an FCC product recovery section. The oligomerization catalyst may have a low silica base with a Group VIIIB metal and operate at low pressure without excessive deactivation. The catalyst is resistant to feed impurities such as hydrogen sulfide, carbon oxides, hydrogen and ammonia. At least 40 wt-% of the ethylene in the dilute ethylene stream can be converted to heavier hydrocarbons. | 10-06-2011 |
| 20150065773 | Oxygen Storage and Catalytic Alkane Conversion - The inventing relates to hydrocarbon conversion, and more particularly to catalytically converting alkane in the presence of oxygen released from an oxygen storage material. Conversion products include C | 03-05-2015 |
| 20150073193 | Process for Nitrile Removal from Hydrocarbon Feeds - A process is described, such process comprising i) contacting a hydrocarbon feed with a heterogeneous catalyst under conditions suitable to hydrolyze nitriles present in the feed to form a nitrile hydrolysis product comprising ammonia, carboxylic acid and carboxylate salts or a mixture thereof; and ii) removing the nitrile hydrolysis product from the feed. In an embodiment, the hydrocarbon feed comprises olefins and is intended for use in an olefin oligomerization process. | 03-12-2015 |
| 20150307414 | Processes for Treating Olefin Feedstreams and Related Oligomerization Processes - Embodiments disclosed herein relate to a process for the oligomerization of olefins, the process including at least one olefin feedstream that includes ammonia and contacting the at least one olefin feedstream with a liquid including alkaline water to remove at least a portion of the ammonia to produce at least one treated olefin feedstream and subsequently contacting the at least one treated olefin feedstream with a catalyst under oligomerization conditions to produce an oligomer product. In several embodiments disclosed herein, the at least one olefin feedstream includes one or more C | 10-29-2015 |
| 585519000 | Removal of hydrocarbon fraction | 1 |
| 20090203947 | Method for Oligomerization of Ethylene and Reactor System therefor with Cooling Device - The present invention relates to a method for oligomerisation of ethylene to form linear alpha-olefins in an oligomerisation reactor in the presence of solvent and catalyst, wherein a reaction product containing unreacted ethylene and light linear alpha-olefins is discharged from the oligomerisation reactor and passed to at least one first direct cooling device for separating the reaction product into an ethylene rich gaseous fraction and a light linear alpha-olefins rich liquid fraction, wherein at least a portion of the light linear alpha-olefins rich liquid fraction is passed to a second cooling device for lowering the temperature thereof and is subsequently re-introduced into the first direct cooling device; and to a reactor system therefore. | 08-13-2009 |
