Abstract: 186,139. Terrisse, H., and Levy, M. June 20, 1921. Addition to 143,212. Glucose.-In the process for obtaining dextrin and glucose from wood by treating it first with liquid and then with gaseous hydrochloric acid as described in the parent Specification, the wood after treatment with acid is spread into thin layers and allowed to digest. The resulting material is of a loose powdery texture so that the acid can easily be extracted from it. The material is carried by worm conveyers 2 through a series of stoneware or like tubes 1<a>, 1<b>, 1<c>, while 40 per cent hydrochloric acid is admitted to the tube 1<a> from a perforated pipe 6, and gaseous hydrochloric acid is admitted to the tubes 1<b> and 1<c>. Water is sprayed on the outside of the tubes to cool them. From the tube 1<c> the treated wood passes to a chamber B containing a number of travelling bands 10<a> - - 10<f>, on which it is spread in thin layers, and is subjected for a period of up to 11 hours to a temperature between 12‹ and 50‹ C., and a pressure of about 1 cm. of mercury. From the chamber B the wood passes to a chamber C containing a number of heated hollow floors 15<a> - - 15g. The odd floors 15a, 15<c> &c. are of greater diameter than the even floors 15b, 15<d> &c. and are formed with central openings 18. The material is carried over the floors by scrapers 21 carried by arms 20 on a central shaft 22 and passes through the openings 18 and over the edges of the floors 15b &c. The temperature is maintained at 15‹-30‹ C., and the evaporated hydrochloric acid gas is removed, compressed and re-used. The material passes into another chamber similar to the. chamber C but maintained at a temperature of about 50‹ C. and a pressure below atmospheric. The vapours are passed through a washing vessel, so that the liquid and gaseous hydrochloric acid used are recovered in nearlv their original forms. The treated wood is boiled in water and the resulting solution filtered, neutralized and ccncentrated or fermented.

Title: Improvements in or relating to the preparation of barium aluminates
IPC: C01F7/168
Filed: 1942-12-04
Abstract: 571,466. Barium aluminates. NATIONAL LEAD CO. Dec. 4, 1942, No. 17280. Convention date, Oct. 24, 1941. [Class 1 (iii)] Barium aluminates are prepared by heating a mixture of a barium sulphate material and an aluminium oxide material, including materials such as bauxite and aluminium hydrate yielding aluminium oxide on heating, the molar ratio of BaO to Al2O3 being at least 1 : 1, first under oxidizing conditions until the barium sulphate content of the mixture is below 40 per cent. by weight and then under reducing conditions until the barium sulphate is substantially completely eliminated. A mixture of the initial materials, for example borite and bauxite, of about 100 mesh size is introduced either dry or wet into a furnace, preferably a rotary kiln lined with a high alumina refractory. This may be operated continuously and coal, oil or gas fired to heat the charge to about 1,400-1,550 C. without liquefaction. Excess of air is used to give oxidizing conditions until the desired decrease in barium sulphate content is obtained, sulphur dioxide being evolved. With large batches the initial temperature may be below 1,400 C. and slowly raised thereto. After one hour at 1,500 C., for example, conditions may be changed to reducing when sulphur elimination is increased and, after another 1-3 hours, the barium sulphate content is 1-4 per cent. Reduction should be mild until this content falls below 20 per cent., and may be strong when below 10 per cent., whereby sulphide formation is avoided. With electric furnaces, air or other oxidizing gas is introduced during the initial heating while a reducing gas such as carbon monoxide is supplied during the later stages or powdered carbon may be sprayed in above the charge. The molar ratio of BaO to Al2O3 in the charge may vary from 1 : 1 to 6 : 1. In examples: (1) a borite ore and bauxite are ground, mixed as an aqueous slurry in proportions to give a molar ratio of BaO to Al2O3, of 3 : 1, dried, and fed to a rotary oil fired furnace. After 3¢ hours under oxidizing conditions, 1,500 C. is reached After a further hour, reducing conditions are imposed for 1 hour; (2) the same materials mixed to give a molar ratio of 6 : 1 are heated to 1,500 C. in 3¢ hours under oxidizing conditions in a magnesium oxide crucible in an oil fired pot furnace. After another hour, reduction is imposed for 36 hours; (3) the molar ratio is 1 : 1 and temperature 1,470 C.; (4) a 4-ton batch, molar ratio 3 : 1, is fed to a rotary furnace at 1,100 C., which is gradually raised to 1,400 C. The burner is then adjusted to give mildly reducing conditions and after a total time of 7 hours, the temperature is 1,540 C. Oxidation is then effected for a further hour to remove any sulphide. In these examples, the barium sulphate content is reduced to 20 per cent. or less before changing to reducing conditions.
