  • Patent number: 4207211
    Abstract: A catalyst is provided for the steam reforming of normally liquid hydrocarbons to produce carbon monoxide and hydrogen, which does not promote the deposition of carbonaceous materials upon the catalytic surfaces. The catalyst consists of nickel promoted with the oxides of iron and manganese within a specific manganese to iron ratio, said metal and metal oxides being supported upon a refractory support. The support is preferably aluminum oxide in its alpha phase having a surface area of less than 15 m.sup.2 /gm. The metallic constituents are impregnated onto said refractory low surface area support as salts and are calcined at sufficiently high temperature to convert the salts to the oxide but at a sufficiently low temperature that they do not chemically react with the support.

  • Patent number: 4167434
    Abstract: A universal drapery making machine having a horizontal working table for handling a drapery panel that has its bottom edge and its two side edges hemmed at prior stations, and an unfinished top edge of the drapery. The operator is able to attach the bottom edge of the drapery panel face down to a transverse bar that is movably supported over the top planar surface of the table. Motive means moves the bar toward the rear edge of the table, and the panel is then measured to size, and the top edge of the drape is simultaneously cut and a stiffening tape such as buckram with its own adhesive strip is attached along the cut edge. Then this stiffened edge is manually folded over twice and stapled temporarily in place so the drapery may be removed to a later station for forming the pleats in this header. The table is pivotally supported by a transverse pivotal support means.

  • Patent number: 4160806
    Abstract: A mobile catalyst treatment unit and process of operating same involves a closed gas processing loop supported on a normally mobile carrier such as a flat truck bed or trailer which is connectable with the inlet and outlet of a catalytic reactor. The normal process gas is cut off from the catalytic reactor so as to isolate the catalyst and to place the gas processing loop into communication with the reactor. Thereafter, the catalytic reactor can be purged of reducing gases and then treated with an oxidizing gas to burn off carbonaceous materials from the catalyst surface, in the process known as regeneration, or the catalyst can be treated with a reducing gas in the process known as reduction, or the catalyst can be heated for startup purposes, or cooled down for purposes of unloading or other mechanical work on the reactor or treated with other treatment gases such as hydrogen sulfide for sulfiding and the like.

  • Patent number: 4153580
    Abstract: A catalyst for the conversion of carbon monoxide in synthesis gas mixtures to hydrogen and CO.sub.2 and which is active in the presence of sulfur compounds, comprises the oxides or sulfides of cobalt and molybdenum, supported on a shaped, relatively high surface area aluminous carrier. The carrier is stabilized by admixture with one or more rare earth metal oxides while the alumina is in the hydrated condition. The mixture of hydrated alumina and rare earth metal oxide is formed into a desired shape and calcined to convert the hydrated alumina to the oxide. Thereafter, the calcined, high surface area alumina is impregnated with the desired salts of cobalt and molybdenum and the impregnated catalyst is thereafter calcined and placed into service. The stabilized catalyst exhibits good activity at relatively low temperatures with synthesis gas mixtures containing sulfur compounds and retains its surface area and the aluminous carrier is not converted over to the alpha phase.
