Title: Process for decomposing aluminium nitrate nonahydrate
IPC: C01F7/308
Filed: 1966-07-15
Abstract: Nitric acid and alumina are produced from aluminium nitrate nonahydrate by melting the Al(NO3)39H2O and heating under a pressure of at least 1.75 kg/cm.2 at a temperature which is high enough to cause decomposition of the aluminium nitrate but is below 230 DEG  C. until 45-60% of the nitric acid values originally in the Al(NO3)39H2O have been removed as gaseous decomposition products.  The pressure is then reduced to atmospheric or below thus releasing additional nitric acid values.  The molten residue is then cooled to below its softening point and maintained at a temperature between 120 DEG  C. and the softening point for at least 1/2 hour, thus releasing further nitric acid values.  The solid residue from the last step is easily friable and may be calcined at 260-375 DEG  C. to remove the remainder of the nitric acid and may be thereafter, calcined at 1000-1300 DEG  C. to produce pure alpha alumina.

Abstract: 506,532. Cracking oils. TOVOTE, H. G. Nov. 30, 1937, No. 33011. Convention date, Dec. 1, 1936. [Class 32] The solidification point of hydrocarbon mixtures containing paraffin wax is lowered by prelieating the raw material, e.g. petroleum residues or distillates, from 752 to 896‹ F. (preferably 824 to 869‹ F.) and passing it into contact with masses having an extensive surface area for a regulated time of 10 to 60 minutes, the temperature and the duration of the contact being regulated so that the formation of fractions boiling below 356‹ F. is restrained. Contact materials specified comprise gas cokes, cokes produced by carbonizing lignites or cracking lignite tars or mineral oils, pumice, blast furnace slags, limonite, oolitic iron ore, bauxite, or cokes covered with sodium silicate. Pressures of 88 to 440 lb. per sq. inch are employed. The crude material is pumped through a tubular heater A, where it is heated to 18-45‹ F. above the reaction temperature. under a pressure of 147 lb., into a chamber B the lower portion of which is filled with contact material contained in a basket B<1> and maintained at' 752-896‹ F. under a pressure of 147 lb.
