  • Patent number: 9315738
    Abstract: A preferred embodiment of a system for loading catalyst and/or additives into a fluidized catalytic cracking unit includes a bin for storing at least one of the catalyst and/or additives, and a loading unit in fluid communication with the storage bin and the fluidized catalytic cracking unit on a selective basis. The loading unit is capable of being evacuated so that a resulting vacuum within the loading unit draws the catalyst and/or additive from the bin. The loading unit is also capable of being pressurized so that the catalyst and/or additive is transferred from the loading unit to the fluidized catalytic cracking unit.

  • Publication number: 20150375201
    Abstract: The invention relates to a novel method of preparing attrition resistance spinel supports for Fischer Tropsch catalysts. The process comprises: (a) combining aluminum oxide, metal compound capable of forming spinel phase, and soluble compound of a trivalent aluminum; (b) mixing the combination resulting in (a) in a manner sufficient to form a slurry comprising the aforementioned combination; and (c) processing the mixture of (b) under conditions sufficient to form metal aluminate spinel composition. Metal aluminate spinel, for example, is formed in the last step by calcining the mixture from (b) at a temperature in the range of 700 to 1300° C., but the process is also capable, of producing attrition resistant supports (e.g., having a DI of 5 or less) at a relatively lower temperature in the range of 700 to 1050° C. The invention also produces the attrition resistance with lower metal loadings than that reported for prior attrition resistant spinel supports.

  • Patent number: 9133286
    Abstract: The present disclosure is directed to the production of substituted phenylene aromatic diesters and 5-tert-butyl-3-methyl-1,2-phenylene dibenzoate (or “BMPD”) in particular. The processes disclosed herein produce a liquid BMPD product. The liquid BMPD product unexpectedly creates production efficiencies by reducing the number of production steps, reducing the amount and/or number of reagents required for BMPD production. The liquid BMPD product may also be utilized in procatalyst production yielding similar production efficiencies. The procatalyst composition is subsequently used for olefin polymerization.
