  • Patent number: 4201691
    Abstract: An apparatus is disclosed for generating a multiple phase dispersion and distributing said multiple phase dispersion as globules in a suspension phase. The apparatus comprises a conduit for introducing a first fluid under pressure into a first zone including a porous fluid dispersing layer. This first zone is in fluid communication with a second zone through the porous fluid dispersing layer. The second zone has introduced into it a second fluid under pressure through inlets. The first fluid is dispersed as bubble-like micro droplets in the second fluid by passage from the first zone through the fluid dispersing layer into the fluid in the second zone. An outlet zone is in contact with the second zone and comprises a perforated nonporous layer having an outer and inner surface and includes a porous flow distribution layer substantially in contact with the inner second zone facing surface of the nonporous layer.

  • Patent number: 4183962
    Abstract: The instant invention relates to an improved process for oxygenating blood comprising: contacting said blood with oxygen-containing bubbles, said bubbles being coated with a liquid membrane, said liquid membrane phase permitting the permeation of oxygen into the blood whereby at least a portion of said oxygen passes through said membrane and into said blood; removing said liquid membrane coated bubbles as a three phase foam comprising gas bubbles coated with said liquid membrane suspended in blood; and coalescing said foam comprising gas bubbbles to form three separate bulk phases comprising the liquid membrane phase, a gaseous phase and a blood phase, wherein the improvement comprises a liquid membrane phase comprising a biologically non-retainable liquid halocarbon compound. These liquid membrane formulations having a membrane phase comprising a biologically non-retainable liquid halocarbon compound exhibit improved coalescing characteristics.

  • Patent number: 4171320
    Abstract: An improved method for the synthesis of hydrocarbons with reduced methane formation and for the selective generation of olefinic hydrocarbons, preferably C.sub.2 -C.sub.5 olefins inclusive, which method comprises the steps of passing a CO and H.sub.2 synthesis gas stream over a catalyst at a temperature and pressure for a time sufficient to generate the desired olefinic products, wherein the improvement consists in using as a catalyst ruthenium on a support comprising at least one refractory Group VB metal oxide. The weight loading of the ruthenium may range from about 0.01 to about 15 wt. % based on the total catalyst weight. The ruthenium average crystallite size is preferably less than 5 nm (50A). The operating conditions of the instant process are typical for Fischer-Tropsch synthesis.

  • Patent number: 4145314
    Abstract: The instant invention relates to a method of preparing highly dispersed supported Group VIII metal catalysts. The instant invention further relates to the redispersion of sintered or agglomerated supported Group VIII metal catalysts. The process comprises the formation of supported Group VIII metal-phosphorus intermediate compounds followed by the treatment of these supported Group VIII metal-phosphorus compounds in an inert atmosphere at a temperature in the range of about 400.degree. C. to about 750.degree. C., preferably, about 550.degree. C. to about 700.degree. C., most preferably from 630.degree.-700.degree. C. The composition resultant from the dispersion heating step will form the highly dispersed, supported Group VIII metal catalysts by decomposition when reacting with an oxygen containing atmosphere, e.g. air, or reacting with water.

  • Patent number: 4041087
    Abstract: Halogenated hydrocarbons are selectively prepared under mild reaction conditions by flowing a gaseous mixture of H.sub.2, CO, and halogen selected from the group consisting of chlorine, bromine and iodine over a well-dispersed supported catalyst system, such as Pt/Re, Pt/Ir, Pt, Ir and Re on an acidic support such as Al.sub.2 O.sub.3, SiO.sub.2 -Al.sub.2 O.sub.3 or zeolites. The reaction occurs over a broad temperature range of from 200.degree. to 1,000.degree. C and a pressure of from 0.1 to 500 atmospheres.
