20110042895 | WORLD ENVIRONMENT/CARBON CREDIT TRADING GAME - A game is disclosed, the game simulating the effects of players' personal and/or business decisions on the environment. The game includes a simulated carbon credit trading scheme and system, and an indication means for indicating the health of a simulated world environment, where this indication means may be varied in response to players' actions. Related methods for playing the game are also disclosed. | 02-24-2011 |

20080312484 | Low Corrosion In Zeolite Oligomerisation - Water reacts on molecular sieve catalysts used in oligomerisation reactions and forms oxygenated compounds, in particular organic acids that may cause corrosion problems downstream of the reactor, in particular in distillation tower overhead systems and downstream thereof. A lowering of the presence of water in the feed prior to contacting thereof with the molecular sieve brings a significant reduction in corrosion downstream. At the same time, it has a significant beneficial effect on catalyst activity and brings a significant extension of catalyst life. Lowering water in the feed is particularly effective when organic nitrogen-containing Lewis bases are present in the feed, even at low levels. | 12-18-2008 |
20120116141 | Oligomerisation Of Olefins With Zeolite Catalyst - The conversion and run length for oligomerisation of olefins over a molecular sieve catalyst in a tubular reactor is improved by controlling the peak temperature to not exceed 50 degrees C. above the temperature of the temperature control fluid exiting the shell side outlet of the reactor. A tubular reactor containing molecular sieve catalyst is provided with a multipoint thermocouple in at least one tube, and optionally with a bottom design adapted for fast unloading of the molecular sieve catalyst from the tubular reactor. | 05-10-2012 |

20120283465 | Oligomerisation Process - The startup of a tubular reactor containing fresh or regenerated molecular sieve catalyst and cooled by steam generation on the shell side, as part of an olefin oligomerisation process, is improved by, during the startup phase of the reactor, controlling the pressure on the shell side of the reactor at maximum 10 barg. The startup may be further improved by controlling the inlet temperature of the hydrocarbon startup stream to the reactor, by controlling the flow of reactant olefins to the reactor, or by controlling the nature and/or concentration of the olefins in the reactor feed. | 11-08-2012 |

20130204060 | Regeneration of Oligomerisation Catalysts and Their Use - Deactivation of a zeolite catalyst during its use to catalyse the oligomerisation of olefins, is often believed to be a result of the formation of high boiling polymers as by-products. These by-products can remain on the catalyst and undergo further conversion to higher molecular weight polymers, which resemble heavy tars and in some cases even have the appearance of coke-like material. These materials can coat the catalyst particles and plug pores in the catalyst, thereby causing catalyst deactivation. The invention relates to an improved method for regenerating such a catalyst. | 08-08-2013 |

20090221862 | Oligomerisation of Olefins - Olefin feeds with high olefin content and/or containing a substance that generates water when contacting the catalyst, are oligomerised over solid phosphoric acid catalyst in tubular reactors by introducing the olefin feed into the reactor and maintaining the reacting mixture under conditions whereby the peak temperature is controlled to be below 265° C. and preferably a single liquid or dense phase is maintained and the average temperature throughout the reactor is maintained in the range 190° C. to 260° C. | 09-03-2009 |
20110124827 | Oligomerisation of Olefins - In the oligomerisation of olefins in a tubular reactor employing a molecular sieve catalyst, the temperature of the reaction is monitored and the space velocity of the olefin feed to the reactor is reduced as the temperature increases. This has been found to increase catalyst life and lead to extended production runs. Further extensions of the production run are achieved by improving reactor operating stability as the end of the production run approaches. | 05-26-2011 |
20110282092 | Lowering Nitrogen-Containing Lewis Bases In Molecular Sieve Oligomerisation - Nitrogen-containing Lewis bases act as poisons for molecular sieve catalysts used in oligomerisation reactions. Lowering their presence in the feed prior to the contacting thereof with the molecular sieve brings a significant extension of catalyst life. Thus, processes that are directed to the lowering of these poisons are provided. | 11-17-2011 |

20100331591 | Olefin Oligomerization Process - In a process for oligomerizing an olefinic hydrocarbon feedstock comprising at least 65 wt % olefins and/or sulfur-containing molecules, the feedstock is contacted under oligomerization conditions with (a) a first unidimensional 10-ring molecular sieve catalyst and (b) a second multidimensional crystalline molecular sieve catalyst. The first and second catalysts may be contained in separate reactors or as separate beds in a single reactor. | 12-30-2010 |
