| 20090163681 | Fast Activating Catalyst - A method of preparing a catalyst comprising aging a silica support in an alkaline solution to produce an alkaline aged silica support, removing at least a portion of the alkaline solution from the alkaline aged silica support to produce a dried silica support, and activating the silica support to produce a catalyst composition, wherein alkaline aging lowers the surface area of the silica support to less than about 50% of the original value and wherein activation of the silica support is carried out in batches of equal to or greater than about 500 lbs for a time period of less than about 8 hours. A method of preparing a polymer comprising alkaline aging a silica support material, adding chromium to the silica support material prior to the alkaline aging, after the alkaline aging, or both to form a chromium-silica support, rapidly activating the chromium-silica support produce an activated olefin polymerization catalyst, contacting the activated olefin polymerization catalyst with at least one monomer in a reaction zone under conditions suitable to produce a polymer, and recovering the polymer. | 06-25-2009 |

| 20120022692 | PREDICTION AND CONTROL SOLUTION FOR POLYMERIZATION REACTOR OPERATION - Techniques and systems for the prevention of reactor fouls in polymerization reactors are described. Described embodiments include techniques and systems for performing analyses on reactor data collected over time for the detection of incipient reactor fouling. Techniques are provided for monitoring the state of the reactor as well as for monitoring individual system parameters, including rates of change, for predicting the onset of a reactor foul. In particular, the techniques may be implemented such that predictive proactive control systems may be integrated into polymerization reactor systems to prevent reactor fouling. | 01-26-2012 |
