    摘要： A process for producing an isotopically enriched compound of a desired isotope includes (a) providing a cryogenic reaction zone containing a catalyst adapted to catalyze an isotope exchange reaction at a cryogenic reaction temperature, (b) feeding to the cryogenic reaction zone an enriched mixture comprising at least a compound containing the desired isotope, wherein the enriched mixture is enriched in the desired isotope above a natural abundance of the desired isotope, (c) reacting the enriched mixture in the cryogenic reaction zone thereby forming a resulting mixture containing the isotopically enriched compound, and (d) separating the resulting mixture into an enriched product which is enriched in the isotopically enriched compound and a depleted product which is depleted in the isotopically enriched compound.

    摘要： A method to reduce or attenuate the amplitude of time-variant properties of a fluid stream by introducing the stream into a defined enclosed volume in a controlled manner such that the residence time distribution of the fluid exiting the enclosed volume approaches that of a preferred flat residence time distribution. This is accomplished by the concept of temporal mixing in which different residence times are imparted to a fluid in a mixing zone by physically dividing the fluid into individual portions, each of which has a different residence time while passing through the mixing zone. The desired fluid portions are created by means of specifically-designed multiple inlets into the mixing zone and/or by means of specifically-designed multiple outlets from the mixing zone.

    摘要： Apparatus for attenuating the amplitude of a time-variant property of a fluid stream which comprises an enclosed volume, wherein the enclosed volume includes a mixing zone having an inlet and three or more outlets; piping means for introducing an inlet fluid stream into the inlet of the mixing zone; and piping means for withdrawing from the mixing zone three or more individual fluid portions through the three or more outlets and combining the three or more individual fluid portions into an outlet fluid stream. The distance between at least one pair of adjacent outlets may be different than the distance between another pair of adjacent outlets, and the distance between adjacent outlets may decrease as the distance of each outlet from the inlet increases.
