Abstract: 682,177. Oxo synthesis. STANDARD OIL DEVELOPMENT CO. May 18, 1949 [July 30, 1948], No. 13298/49. Drawings to Specification. Class 2 (iii). Dissolved metal carbonyl is removed from the products, mainly aldehydes and alcohols, of the reaction of olefinic compounds with CO and H 2  in the presence of carbonylforming metals, by treating said product in the liquid phase at a temperature sufficiently elevated to give a carbonyl decomposition rate substantially higher than the rate of condensation and polymerization of aldehyde components of the product, and a pressure not substantially greater than that required to prevent substantial vaporization of liquid, said temperature being maintained by heat exchange between said products and a highly heated fluid. Reaction conditions are suitably 150- 450‹ F., 100-300 atm., and H 2  : CO of 0.5- 4 : 1 with iron group metals. Dissolved gases are separated prior to or during the thermal treatment and a stripping gas may be used. Carbonyl removal may be effected at 200- 400‹ F. and 50-150 p.s.i.g. from a product averaging 6 or more C atoms per molecule made with a cobalt catalyst. For a 9 or more C atom product, pressure may be 0-100 p.s.i.g. The heat may be supplied by means of steam jacketing, by mixing the products with preheated carbonyl-free fluid which may be an inert gas or liquid, particularly a previously purified reaction product, or by immersing heating surfaces in the product. Thus, the product may flow through a relatively wide tube having therein a steam coil of narrow bore. A stripping gas, preferably hydrogen, may be passed up the tube. The products, after purifying, may be hydrogenated to alcohols. Specifications 629,915 and 672,880 are referred to.

Title: Improvements in or relating to cooling section of a forehearth for molten glass
IPC: C03B7/06
Filed: 1955-05-12
Abstract: 768,932. Glass manufacture. EMHART MANUFACTURING CO. May,12, 1955 [June 24, 1954], No. 13793/55. Class 56 The cooling-section of a forehearth of a glass-melting furnace is provided with heating and cooling means which are used as required to produce substantial uniformity of temperature throughout the section of the glass at the spout. The molten glass passing from the' furnace to the cooling section of the forehearth at 11, flows over refractory bottom blacks 10a, 13, the latter sloping downwardly, and under a roof 22 supported by side blocks 21. The slide blocks 21 rest upon burner blocks 20. The part of the glass-flow passage used as a cooling-section is divided into temperature control zones separated by baffle blocks 26, 28 which nearly touch the flowing glass and prevent exchange of gases between the zones. The side blocks 21 are formed with channels 30, 31, the former being for the admission of cooling air which travels under. the concave roof to the exhaust channel 31 which is nearly opposite to it in the opposing block 21. The blocks 21 thus have alternating air-admission and exhaust ports and the oppositely moving streams brush one another and produce eddies in the concavity 41. The exhaust air is led to passages 32 in the roof blocks 22, the bottom of these passages being corrugated at 35 to make efficient use of the cooling air both at upper and under sides of the blocks 22. The effect of the cooling air is to cool the glass stream more at the top than at the bottom. To counter this effect, the cooling-air may be cut off in one zone and hot combustion products from the burner blocks used to raise the temperature of the top glass, and possibly the bottom glass, so that in a subsequent zone where cooling-air only is used, the tendency is towards a uniform temperature throughout the glass stream. The length of the cooling section is determined by the number of zones, separated by baffles 26; 28, each zone having its own heating and cooling means.
