    Abstract: 1. A catalyst for hydrazine decomposition consisting essentially of a carrier having a pore volume of at least 0.1 cubic centimeters per gram and a specific surface area, measured in square meters per gram, equal to 195 (C.sub.p + 0.013 + 0.736 V.sub.p) where C.sub.p is the specific heat capacity of the carrier at about 25.degree. C in calories per gram per degree and V.sub.p is the pore volume of the carrier in cubic centimeters per gram and metal of the group consisting of iridium, and mixtures consisting of iridium and ruthenium deposited on said carrier in an amount between 20% and about 40% by weight of the catalyst and distributed through the pores thereof in discrete particles sufficiently separated from each other so that they do not sinter or fuse together when the catalyst is at hydrazine decomposition temperature.

    Abstract: Hydrocarbons are converted by contacting them at hydrocarbon conversion conditions with an acidic multimetallic catalytic composite comprising a combination of catalytically effective amounts of a platinum group component, an iron component, a cobalt or nickel component, and a halogen component with a porous carrier material. The platinum group component, iron component, cobalt or nickel component, and halogen component are present in the multimetallic catalyst in amount respectively, calculated on an elemental basis, corresponding to about 0.01 to about 2 wt. % platinum group metal, about 0.1 to about 5 wt. % iron, about 0.1 to about 5 wt. % cobalt or nickel, and about 0.1 to about 3.5 wt. % halogen. Moreover, these metallic components are relatively uniformly dispersed throughout the porous carrier material in carefully controlled oxidation states such that substantially all of the platinum group component is present therein in the elemental metallic state, substantially all of the catalytically available cobalt or nickel component is present in the elemental metallic state or in a state which is reducible to the elemental metallic state under hydrocarbon conversion conditions or in a mixture of these states, while substantially all of the iron component is present therein in an oxidation state above that of the elemental metal. A specific example of the type of hydrocarbon conversion process disclosed is a process for the catalytic reforming of a low-octane gasoline fraction wherein the gasoline fraction and a hydrogen stream are contacted with the acidic multimetallic catalyst disclosed herein at reforming conditions.

    Abstract: This invention relates to a process for preparing catalysts comprising two or more immiscible metals, said process comprising the step of incorporating an additional metal into said catalyst, said additional metal being characterized as being highly miscible with each of said immiscible metals whereby a catalyst is formed, wherein each metal is more miscible in the total metal mixture. In one preferred embodiment, this invention relates to a method for preparing multimetallic reforming catalysts wherein said metals are supported on a refractory oxide support. Catalysts prepared by the instant method are characterized as having increased stability due to the mutual miscibility of all the metals in the catalyst. In a specific embodiment, Group VIII - Group IB metal pairs having low miscibility, and which form useful bimetallic reforming catalysts because of the ability of Group IB metals to selectively inhibit the hydrogenolysis properties of Group VIII metals, are rendered more stable by the addition of a different Group VIII metal which acts to solubilize the first Group VIII metal and the Group IB metal in the total metal mixture. A specific improved catalyst results from the addition of nickel to a ruthenium-copper system; nickel acts to make the ruthenium and copper miscible in the total mixture. Similar results are found for Ru-Pt-Cu, platinum being the stabilizing Group VIII metal. Various catalysts prepared by the process of the instant invention are novel compositions of matter.

    Abstract: A catalytic resistance element for use in a gas analyzer has an outer layer formed of particles of a metallic oxide, such as beryllium or aluminum, of about one micron average size, the outer layer preferably being of from about 100 to about 500 microns in thickness. The oxide particles have catalytic coatings formed by mixing the particles with a solution of a compound which is decomposed by heating to coat the particles with the catalyst and heating the mixture to cause such decomposition and coating. The outer layer is applied by mixing the oxide particles with binder solution, and applying drops of the mixture to the resistance element.

    Abstract: An all metal, high temperature resistant, catalyst element is provided by plating or depositing a noble metal comprising platinum and/or palladium onto a base material which comprises primarily aluminum, chromium and iron. The nickel-free, aluminum containing base material appears to be of advantage for at least certain all metal catalyst element operations and also results in substantially lower first cost catalyst units.
