| 20110160509 | PROCESS FOR THE PREPARATION OF AN OLEFIN - An olefin is prepared from an alkyl alcohol in a process which comprises the steps: a) converting the alkyl alcohol into a dialkylether over a first catalyst, to yield a hot dialkylether product stream containing alkyl alcohol, dialkylether and water; b) cooling the hot dialkylether product stream at least partly by indirect heat exchange with a cold dialkylether product stream to below the dew point of water at the prevailing conditions to obtain a gas-liquid mixture; c) separating the obtained mixture into a liquid water-containing stream and a vaporous dialkylether-rich stream; d) subjecting at least part of the vaporous dialkylether-rich stream, as the cold dialkylether product stream in step b), to heat exchange with the hot dialkylether product stream, to yield a heated dialkylether-rich feed; and e) converting the heated dialkylether-rich feed to an olefin over a second catalyst. | 06-30-2011 |
| 20120116142 | Method and System for Performing Chemical Proceses - The invention relates to a method for performing chemical processes, where raw materials are heated, wherein a melt pool is produced in a tank or reactor using low-melting metals or metal alloys, wherein the raw materials are metered directly into the melt pool in the lower part of the tank or reactor. | 05-10-2012 |
| 20120330079 | PROCESS FOR THE PRODUCTION OF OLEFINS - Disclosed is a process for the production of C2 to C3 olefins via the catalytic cracking of feedstocks including C4 and heavier olefins in an integrated reaction/regeneration system. | 12-27-2012 |
| 20130158326 | DUAL RISER CATALYTIC CRACKER FOR INCREASED LIGHT OLEFIN YIELD - A process for improving the yield of ethylene and propylene from a light naphtha feedstock includes obtaining light naphtha feedstock from a primary cracking zone having a cracking catalyst. The light naphtha feedstock is contacted with an olefin catalyst in an olefin producing zone to produce an ethylene- and propylene-rich stream. After reacting with the olefin catalyst, the ethylene- and propylene-rich stream is separated from the olefin catalyst from in a separator zone. At least a portion of the olefin catalyst is regenerated by combusting coke deposited on a surface of the olefin catalyst in an oxygen-containing environment, and at least a portion of the olefin catalyst is heated. These portions could be the same one or they could be different. In some embodiments, at least a portion of the olefin catalyst could be neither regenerated nor heated. The olefin catalyst is returned to the olefin producing zone. | 06-20-2013 |
