Title: Process for imparting increased activity to inorganic solid contact material
Inventor: NIXON WILLIAM GALLOWAY
IPC: B01J23/42
Filed: 1961-03-21
Abstract: Increased activity is imparted to an adsorptive refractory inorganic oxide by contacting the inorganic oxide, while in a hydrous state, at a temperature in excess of 100 DEG  C. with sulphur trioxide in a non-reducing atmosphere. The refractive inorganic oxide can be alumina, silica, magnesia, thoria, zirconia, titania, boria or mixtures of two or more of these oxides; they may be naturally occurring earth, clays, sands and/or minerals, or they may be synthetically prepared.  The invention is particularly applicable to alumina, silica and mixtures of the two. In a specific embodiment an adsorptive refractory inorganic oxide material which has not been heated to any temperature above 150 DEG  C., is contacted with sulphur trioxide between 100 DEG  and 500 DEG  C. in a non-reducing atmosphere and the oxide is then calcined at a temperature of at least 500 DEG  C.  To ensure the non-reducing atmosphere the adsorptive refractory inorganic oxide may be purged, prior to the sulphur trioxide treatment, with any suitable gaseous material which reacts neither with the refractory oxide nor with the sulphur trioxide, e.g. air, nitrogen, argon and other inert gases may be used. In the example, wet calcined alumina spheres prepared by the oil drop method are washed with methyl alcohol and water to remove any contaminants and allowed to dry in air at room temperature. A portion of the dried spheres are treated with a sulphur trioxide gas mixture formed by the oxidation of sulphur dioxide with air over a platinum catalyst, the temperature being gradually increased from 150 to 500 DEG  C.  The treated alumina had a surface area of 325 sq. metres/gm.-a 62% increase over untreated alumina.ALSO:A solid contact material consisting at least predominantly of an adsorptive refractory inorganic oxide which has been activated by contacting the inorganic oxide component while in a hydrous state, at a temperature greater than 100  DEG C. with sulphur trioxide in a non-reducing atmosphere (see Division C1), is used as a carrier for a catalytically active metal component.  The adsorptive refractory inorganic oxide is first activated as above and then impregnated with a minor proportion of a catalytically active metal component; metal components mentioned are platinum, iridium, palladium, ruthenium, rhodium, osmium, iron, cobalt, nickel, chromium, molybdenum, and tungsten.  The amount of metal component used is generally such that the final catalyst composite contains 0,01-20% by weight of the metal component.  The carrier material which may for example be alumina, silica, magnesia, thoria, zirconia, titania, boria or mixtures thereof, or a naturally occuring earth, clay, sand, and/or minerals (or a synthetically prepared material), may be impregnated with a halogen and used in the reforming of hydrocarbons.

Title: Improvements in the thermal treatments of materials to be heated, for examplematerials to be annealed
IPC: C21D9/00
Filed: 1963-03-18
Abstract: In a process of heat-treating material, the supply of heat to the furnace is determined at least in part by the variation in furnace temperature resulting from the introduction of the charge, while the furnace is heated at the maximum possible rate until its temperature reaches a predetermined maximum above the desired final temperature, the surface of the charge also being above the desired temperature. The rate of heat supply is then reduced progressively so that the temperatures of the furnace and of the charge surface fall, and the temperature of the core of the charge continues to rise, until all three temperatures reach the desired temperature substantially simultaneously.

Abstract: 601,588. Hardening steel. PURNELL, C. G. July 6, 1943, No. 10975. [Class 72] The structure of hardenable steel is transformed to structures other than coarse pearlite or martensite by heating the structures to convert them to austenite, quenching them at a rate at least equalling its critical cooling rate to a temperature below that at which it will change to the desired structure but below that at which it will change to martensite, e.g. 250- 450 degrees F. and, prior to transformation of any austenite &c. heating it to a higher temperature, e.g. 930 degrees F. at which it will be transformed to structures other than coarse pearlite or martensite and maintaining it at that temperature for a sufficient time to allow the austenite to transform at the higher temperature. The process is carried out in the apparatus shown in Fig. 2, by passing the steel articles on a conveyer 5 through a heating chamber 1 and a soaking chamber 2 and thence down a shoot 6 with a perforated part 6a into a quenching tank 7 containing brine, water or a light oil, a propeller 8 forcing the liquid through the holes in the portion 6a.

The atmosphere in the furnaces 1 and 2 may be an oxidising one such as air so that the scale formed thereon may be dislodged easily in the tank 7 to assist the quenching.
