  • Patent number: 9302910
    Abstract: The invention relates to a short-flow process for desulfurization of circulating hydrogen and a device for the same. A short-flow process for desulfurization of circulating hydrogen is provided, comprising: (a) removing hydrocarbons from the circulating hydrogen mixture, so that the liquid drops of the heavy hydrocarbons in the dispersion phase are separated from the circulating hydrogen in the continuous phase, and a heavy hydrocarbon phase and a mixture phase of circulating hydrogen containing sulfur are obtained; (b) further separating the resultant mixture phase to remove the sulfides therein, so that circulating hydrogen without sulfur is obtained; (c) further separating the resultant circulating hydrogen without sulfur to remove the amine solution therein, so that purified circulating hydrogen is obtained. The invention also provides a device for desulfurization of circulating hydrogen.

  • Patent number: 6583277
    Abstract: The invention provides methods and compositions relating to semaphorin K1 (sema K1) polypeptides which regulate cellular guidance and physiology, and related nucleic acids. The polypeptides may be produced recombinantly from transformed host cells from the disclosed sema K1 encoding nucleic acids or purified from human cells. The invention provides isolated sema K1 hybridization probes and primers capable of specifically hybridizing with the disclosed sema K1 genes, sema K1-specific binding agents such as specific antibodies, and methods of making and using the subject compositions in diagnosis, therapy and in the biopharmaceutical industry.
