摘要： The previously carried out internal coating of contact tubes not only required very much manual labor and was very time consuming, but it was also unsatisfactory in regard to adhesion of the contact liquid to the surface and homogenity of the catalyst. By the simultaneous action of heat on the liquid interface in the tubes during the lowering of the liquid level as well as by a specially suited apparatus for this purpose which operates according to the principle of communicating tubes there is provided the possibility of a good adhesion to the surface as well as the formation of a homogeneous layer at very little operating expense.

摘要： For the reduction of the ammonia content in the product gas of the hydrocyanic acid-methane-ammonia (BMA) process and accordingly to increase the yield the reaction gas mixture of this process is brought into contact with zeolite and the ammonia thereafter desorbed from the zeolite preferably again employed in the reaction step. If the desorption is carried out with a flushing gas such as the hydrocarbon used in the reaction then this mixture can be directly supplied again to the BMA reactor. Through this procedure the amount of ammonia previously lost to the process can again be made useful in the process itself.

摘要： There is provided temperature stabilized pyrogenically produced aluminum oxide-mixed oxide having a BET surface area of 50 to 200 m.sup.2 /g which contains 0.5 to 20 weight % silicon dioxide as a constituent thereof. Because of the silicon dioxide constituent the aluminum oxide does not change into the .alpha.-Al.sub.2 O.sub.3 phase until 1350.degree. C. The temperature stabilized aluminum oxide-mixed oxide is suitable for the production of thermal insulation compositions.

摘要： Thermally split zirconium silicate is produced such that the crystalline zirconium dioxide embedded in an amorphous silica phase exhibits an average grain or particle size (d.sub.50 value) in a range of 0.5 .mu.m to 3.0 .mu.m and a specific surface (BET) in a range of 3 to 15 m.sup.2 /g. The zirconium dioxide produced by this method is particularly suited for the production of zirconium silicate pigments with improved color characteristics. The thermally split zirconium silicate is also particularly well suited for processes used in the obtention of zirconium dioxide. The method of producing the thermally split zirconium silicate includes melting zirconium silicate in an induction melting furnace and cooling off a free falling stream of melt by blowing on it with a gas and/or spraying it with water.

摘要： Molecular sieves are modified by an ion exchange process where metal cations are introduced into the molecular sieves by means of solid state ion exchange. The solid state ion exchange can be carried out as follows: a weighed amount of calcined and activated zeolite is intimately mixed with a precalculated amount of PtCl.sub.2, PdCl.sub.2, RhCl.sub.3, CuCl.sub.2, V.sub.2 O.sub.5 or another compound of the noble metals (e.g., corresponding halides or oxides), the solids mixture is then heated in a current of inert gas (e.g., a current of helium gas or of nitrogen) to temperatures of 400.degree. to 600.degree. C., then cooled down to room temperature and subsequently reduced in a current of hydrogen for 10 to 14 hours at 280.degree. to 350.degree. C. in order to produce small metal clusters from the cationically introduced metal.

摘要： A method is disclosed for the semi-continuous melting of ceramic material by means of inductive melting in high-frequency and medium-frequency induction melting furnaces whose melting coil surrounds a sintering crust crucible and contains a run-out channel. In the method, melt is periodically run out and material to be melted is supplied to the crucible so as to replace the material removed preferably so as to maintain a constant level. An intensively cooled channel is used as a run-out device. For the melt broaching, the melt nose is grasped from below by way of an automatically controllable broaching lance of a broaching device and raised. The broaching lance is then advanced between the bottom of the channel and the solidified melt until the sintering crust is pierced. The method permits a reliable and economic management of the process and the maintenance of the quality of the melted products. A device for periodic melt broaching as well as an induction melting furnace equipped with an intensively coolable run-out channel provides apparatus for carrying out the above method.
