Title: Gasification of liquid hydrocarbons, particularly of residual oils
IPC: C10G9/26
Filed: 1953-02-17
Abstract: 734,222. Oil gas. RUHRCHEMIE AKT.- GES. Feb. 17, 1953 [Feb. 20, 1952], No. 4383/53. Class 55 (2). In the gasification of liquid hydrocarbons such as residual oils by gasifying agents containing free oxygen with or without steam and/or CO 2  the hydrocarbons are injected in a finely divided state in at least two and preferably four directions into a central part of a reaction zone 2a, 2b of a generator, the reaction zone being flanked by packed beds of refractory material 3a, 3b and the arrangement such that the beds 3a, 3b are alternately traversed by the gasifying agent and the gases produced so that any soot from the gases produced deposited in the packed beds is gasified. The packed beds may be composed of refractory particles of fluidizable size so that by upward passage of the gasifying agent a fluidized bed is formed. Soot separators such as cyclones may be arranged externally of the generators to trap any soot in the gases produced not removed by the packed beds and the thus separated soot may be returned to the generator. Alternately the packed beds may be supported on porous material which will filter out the residual soot in the gases and enable it to be gasified in the generator. In a further modification the gases pass from the reaction zone through a porous partition into the packed bed.

Title: An improved manufacture of petroleum products of the type known as "white oils"
IPC: C10G45/04
Filed: 1929-02-09
Abstract: 308,297. Standard Oil Development Co., (Assignees of Haward, F. A.). March 21, 1928, [Convention date]. Mineral oils, purifying &c.-"White oils" are obtained by subjecting crude petroleum or a heavy fraction thereof to hydrogenation, and maybe cracking, by treating with hydrogen at a high temperature and pressure, separating the product having a viscosity of about 50-600 secs. Saybolt at 100‹ F., and further purifying by sulphuric acid, with or without physical treatment, to remove colour, taste, and odour. In an example, Pennsylvania crude oil is treated at 750-850‹ F. and 50-100 atmospheres. Preferably the oil is agitated by continuous injection of hydrogen. The process may be continuous or by batches in a reactor having non- reactive steel alloy surfaces. Metal oxides or other catalysts, a mixture of 9 lb. of chromium oxide with 1 lb of molybdenum oxide, should be suspended in the oil. The cracked, hydrogenated, and desulphurized product is fractionally condensed, treated with 10-50 per cent by volume of 98 per cent sulphuric acid or with fuming sulphuric acid, then with caustic soda solution, blown dry and filtered through Fuller's earth. In a second example, oils containing large proportions of unsaturated compounds, e.g. cracked oils, are hydrogenated without cracking by treatment at 650‹ F. and 100 atmospheres. The Specification as open to inspection under Sect. 91 (3) (a) describes the preparation of other highly purified petroleum oils, and does not limit the final purification to treatment with sulphuric acid. This subjectmatter does not appear in the Specification as accepted.

Title: A process for the production of formaldehyde
Inventor: GERLOFF ULRICH
IPC: C07C31/04
Filed: 1962-02-06
Abstract: In a process for the production of formaldehyde from methanol, crude methanol is submitted to distillation to remove a low-boiling fraction which contains the iron carbonyl contaminants, and the iron-free methanol remaining as residue is subjected to dehydrogenation in the presence of a silver metal catalyst.  The distillation is preferably carried out by introducing the crude methanol into the upper part of a fractionating column having a efficiency equivalent to 2 to 20 theoretical plates, a reflux ratio between 1:10 and 1:100 being employed in the fractionation. In general, the amount of distillate, withdrawn from the top of the column, amounts to 0.2 to 0.4% by weight with reference to the crude methanol. In an example, the iron-free methanol, obtained as distillation-residue, is mixed with 45% by weight of water. The solution is evaporated the vapours are mixed with air, and the vapour-mixture is passed over silver crystals at a temperature of about 625 DEG C. whereby the methanol is converted into formaldehyde.
