  • Patent number: 9476356
    Abstract: Systems and methods are provided for combined cycle power generation while reducing or mitigating emissions during power generation. Recycled exhaust gas from a power generation combustion reaction can be separated using a swing adsorption process so as to generate a high purity CO2 stream while reducing/minimizing the energy required for the separation and without having to reduce the temperature of the exhaust gas. This can allow for improved energy recovery while also generating high purity streams of carbon dioxide and nitrogen.

  • Patent number: 9309472
    Abstract: Methods are provided for improving the yield of distillate products from hydroprocessing of gas oil feedstocks, such as vacuum gas oils. It has been unexpectedly found that stripping of gases or fractionation to separate out a distillate fraction during initial hydrotreatment of a feed can provide a substantial increase in distillate yield at a desired amount of feedstock conversion. The improvement in yield of distillate products can allow a desired level of conversion to be performed on a feedstock for generating lubricating base oil products while reducing or minimizing the amount of naphtha (or lower) boiling range products. Alternatively, the improvement in yield of distillate products can correspond to an improved yield during a single pass through a reaction system, so that distillate yield is increased even though a lubricant boiling range product is not generated.

  • Patent number: 8778171
    Abstract: This invention relates to hydrocracking catalysts utilizing stabilized aggregates of small primary crystallites of zeolite Y that are clustered into larger secondary particles. At least 80% of the secondary particles may comprise at least 5 primary crystallites. The size of the primary crystallites may be at most about 0.5 micron, or at most about 0.3 micron, and the size of the secondary particles may be at least about 0.8 micron, or at least about 1.0 ?m. The silica to alumina ratio of the resulting stabilized aggregated Y zeolite may be 4:1 or more. This invention also relates to the use of such catalysts in hydrocracking processes for the conversion of heavy oils into lighter fuel products. The invention is particularly suited for the selective production of diesel range products from gas oil range feedstock materials under hydrocracking conditions.

  • Patent number: 6896955
    Abstract: A process for depositing porous silicon oxide-based films using a sol-gel approach utilizing a precursor solution formulation which includes a purified nonionic surfactant and an additive among other components, where the additive is either an ionic additive or an amine additive which forms an ionic ammonium type salt in the acidic precursor solution. Using this precursor solution formulation enables formation of a film having a dielectric constant less than 2.5, appropriate mechanical properties, and minimal levels of alkali metal impurities. In one embodiment, this is achieved by purifying the surfactant and adding ionic or amine additives such as tetraalkylammonium salts and amines to the stock precursor solution.
