Patent DE-2429182-A1 (DE)
Title: Defect-zeolites having increased heat- and acid-resistance - produced by leaching out beryllium from alkali beryllo-alumino-silicates
Inventor: STABENOW JOACHIM DIPL PHYS DR
IPC: B01J20/18
Filed: 1974-06-18
Abstract: 'Defect-zeolites' (contg. tetrahedral voids filled with H2O and protons) are produced by selectively removing beryllium from alkali beryllo-alumino-silicates having a faujasite structure (zeolite Y), in which the molar ratio SiO2:al2O3. is 5:1 to 10:1, by treatment with aq. solns. having pH 3.0-5.5 (the soln. may contain buffer substances). The 'defect-zeolites' are used instead or ordinary aluminosilicate zeolites for adsorption or catalysis in cases when improved temp. stability and increased adsorption or catalysis in cases when improved stability and increased adsorption capacity required. After the removal of beryllium, there remains excess SiO2 with respect to Al2O3 (compared with the aluminosilicate zeolites), whereby the acid resistance of the product is also improved. The process results also in an increased average, lattice constant, whereby adsoption is promoted. The crystallinity of the product is not affected otherwise.

Title: Decarburising ferrochrome or ferromanganese - by oxygen blowing with the melt superheated
Inventor: BREUER FRITZ DIPL ING DR
IPC: C21C7/068
Filed: 1975-07-11
Abstract: High carbon ferromanganese or ferrochrome is decarburised by refining using gas envelope nozzles, e.g. with double walls, the molten alloy being super heated before blowing in oxygen to a temp. >100 degrees C above that of the fusion zone. The temp. is further heated by the blowing to 1650-1900 degrees C for ferromanganese and 1750-2000 degrees C for ferrochrome so as to produce a phase of manganese oxide or chromic oxide having a high m.pt.; this oxide phase is subsequently reduced by introducing lime and addn. of solid producing agents such as Si, Al or their alloys. The operation can be effected with improved yield at above the temp. of the molten alloy using much larger charges than in prior art.
