    Abstract: Disclosed is a method for collecting hydrocarbon vapors before they are dispersed in the atmosphere surrounding a site where loading or unloading of flammable fuels occur. The collected vapors are monitored to determine when the air-hydrocarbon vapor mixture is near or in the combustible range. When it is determined that the mixture is near or in the combustible range, a hydrocarbon gas such as propane is injected into the mixture to remove the danger of explosion or fire. The collected vapors are held in a holding tank and, preferably, are periodically burned.

    Abstract: COPOLYMER COMPOSITIONS OF THE AMIDE-IMIDE VARIETY ARE MADE BY POLYMERIZING PRIMARY DIAMINES WITH AZOBENZENETETRACARBOXYLIC ACID DIANHYDRIDE AND AROMATIC POLYCARBOXYLIC ACID ANHYDRIDE COMONOMERS. THE POLYMERS ARE LINEAR, SHAPABLE, HIGHLY-SOLUBLE COMPOSITIONS WHICH AS FORMED CONTAIN AMIDE ACID GROUPS. THE POLYMERS IN DRY POWDER FORM ARE USEFUL FOR COMPRESSION MOLDING AND IN SOLUTION FORM ARE USEFUL FOR ADHESIVE COATINGS, POROUS MATERIAL IMPREGNATING, CASING FILMS, PREPARING FIBERS AND INSULATING COATINGS. THE POLYMERS ARE HEAT-MODIFIABLE CONVERTING TO THE IMIDE FORM AT ELEVATED TEMPERATURES PRODUCING COMPOSITIONS HAVING EXCELLENT SOLVENT RESISTANCE, THERMAL STABILITY AND ELECTRICAL PROPERTIES.

    Abstract: The catalyst comprises a hydrogenation component, a small amount of rhenium, and a small amount of gallium on a solid catalytic support comprising a porous refractory inorganic oxide. The rhenium and the gallium may be present either in the elemental form or as compounds. The preferred hydrogenation component is a Group VIII noble metal and the preferred porous refractory inorganic oxide is a catalytically active alumina. The reforming process comprises contacting a petroleum hydrocarbon stream in a reforming zone under reforming conditions and in the presence of hydrogen with the above-described catalyst. In one embodiment, the process comprises contacting a partially-reformed hydrocarbon stream in a reforming zone under reforming conditions and in the presence of hydrogen with the above catalyst. In another embodiment, the process comprises contacting a naphtha in a reforming zone under reforming conditions and in the presence of hydrogen with the above catalyst. In a third embodiment, the process comprises contacting the petroleum hydrocarbon stream in a first reforming zone under reforming conditions and in the presence of hydrogen with a first reforming catalyst to produce a first reformate and subsequently contacting the first reformate in a second reforming zone under reforming conditions and in the presence of hydrogen with a second reforming catalyst, said second reforming catalyst being the catalyst described in the preceding paragraph.

    Abstract: There is described the separation of aliphatically unsaturated hydrocarbons from mixtures by the combined use of liquid barrier permeation and metal complexing techniques. The liquid barrier is in contact with a film membrane, and the barrier contains complex-forming metal ions in aqueous solution. The metal ions may be, for example, noble metal, mercuric, cuprous or other metal ions, and mixtures of these metal ions, with or without other cations, may be used. The separation of ethylene from ethane and methane is of particular interest.
