| 20090134062 | CATALYST SUPPORT - A catalyst support in the shape of a non-planar ring having a bore; wherein there is no rotational symmetry around the axis extending through the centre of the bore defined by the ring, and wherein the ratio of the thickness of the ring to the outer diameter of the ring is less than 0.5. The catalyst support shape is especially advantageous to pack within a fixed bed multitubular reactor such as that used for Fischer-Tropsch reactions. The packing of such shapes can reduce the pressure drop across the tubes with little or no difference in the porosity. | 05-28-2009 |

| 20110276164 | ADVANCED BATCH CONTROL - A method for advanced batch control of a batch process. The method discloses completing at least one cycle of the batch process and collecting data on at least one process variable and at least one product property. A model is created based on the data, wherein the model comprises inputs. Thereafter the batch process is initiated. At one or more decision points the model is utilized to obtain outputs. A controller utilizes the model outputs to control the batch in accordance with the model outputs. Final product properties are reached at decreased variability compared to the prior art. | 11-10-2011 |
