Size Stratification Prevention Patents (Class 208/170)
  • Patent number: 10457880
    Abstract: The disclosure relates to fuel additive compositions including heavy paraffinic distillates and lighter petroleum distillates, in particular with the heavy paraffinic distillates including a mixture of hydrotreated and/or saturated components and solvent-dewaxed and/or branched components. The disclosure further relates to fuel compositions including the fuel additive composition and a liquid or solid combustible fuel. Related methods include methods of making the fuel compositions and methods of burning the fuel compositions. The resulting fuel compositions have several improved combustion properties such as improved combustion efficiency, improved combustion energy/calorie content, reduced sulfur generation, and reduced ash generation.

  • Publication number: 20030098261
    Abstract: A stable distillate fuel blend useful as a fuel or as a blending component of a fuel that is suitable for use in an internal combustion engine, said fuel blend prepared from at least one highly paraffinic distillate fuel component and at least one highly aromatic petroleum-derived distillate fuel component and a process for preparing same involving the blending of at least two components having antagonistic properties with respect to one another.

  • Patent number: 5498327
    Abstract: This invention makes possible substantially continuous flow of uniformly distributed hydrogen and hydrocarbon liquid across a densely packed catalyst bed to fill substantially the entire volume of a reactor vessel by introducing the fluids as alternate annular rings of gas and liquid (i.e. a mixture of liquid hydrocarbon and a hydrogen-containing gas) at a rate insufficient to levitate or ebullate the catalyst bed. Catalyst are selected by density, shape and size at a design feed rate of liquids and gas to prevent ebullation of the packed bed at the design feed rates. Catalysts are selected by measuring bed expansion, such as in a large pilot plant run, with hydrocarbon, hydrogen, and catalyst at the design pressures and flow velocities. The liquid and gas components of the feed flow into the bed in alternate annular rings across the full area of the bed.
