    摘要: A process is disclosed for reactivating an agglomerated iridium and selenium containing catalyst and particularly platinum-iridium-selenium on alumina reforming catalysts. The process includes contacting a substantially decoked agglomerated catalyst with a reducing gas such as hydrogen to reduce agglomerated iridium oxides present to the free metal, a hydrogen halide pretreatment step to increase the halogen level of the catalyst to about 1.3 weight percent and above, and a redispersion step involving hydrogen halide and elemental oxygen. Use of hydrogen halide and elemental oxygen in the redispersion treatment eliminates the need for use of elemental chlorine gas. If no iridium oxides are initially present, the hydrogen reduction step is optional.

    摘要: A process is described for reactivating agglomerated iridium-containing catalysts such as Pt-Ir on Al.sub.2 O.sub.3 reforming catalyst. The agglomerated catalyst is decoked to remove carbon deposits; treated with hydrogen to reduce metal oxides to the free metals; pretreated with hydrogen halide to provide at least about a 1.3 weight percent halide content; and treated with a low mass flow rate of chlorine of about one gram chlorine per 100 grams catalyst per hour. Use of a low mass halogen flow rate significantly retards ferrous metal corrosion and significantly reduces the quantity of chlorine normally used in achieving high redispersion values.

    摘要: The present invention is a heat pipe having a specified volume of working fluid determined in relation to the interior volume of the heat pipe and a target temperature TT, to provide self-temperature regulation and pressure management. The heat pipe comprises at least a evaporator region and a condenser region having a known interior volume V and a mass of working fluid given by the relationship Mwf=Dwf at TT×V where Dwf is the density of the saturated vapor of the fluid at temperature TT plus an amount of additional working fluid sufficient to have the rate of evaporation about equal to the rate of condensation for the particular heat pipe configuration. The heat pipe has at least the condenser region having an interior coating of a hydrophobic material.
