Title: Improvements in or relating to the production of base exchanging materials
IPC: C01B33/46
Filed: 1936-09-02
Abstract: Material having high base-exchanging properties such as zeolitic clay is rendered more suited to purifying water by roasting in two stages and adding between the stages one or more organic substances adapted on subsequent roasting in the absence of air or in a closed retort to leave a stabilizing residue of carbon in the pores of the grains of the material.  The first roasting step may be carried out at 400-650 DEG  C. and the second at 400-700 DEG C., it being preferred that the temperature used in the second roast be lower than that attained during the first.  As carbon-producing additions sugar solution, molasses, oils, dissolved cellulose, glue, sulphite lye, or tar products are referred to.  The roasted grains may be hardened by treatment with a neutral salt such as calcium chloride and with waterglass, for instance in the manner described in Specification 395,185.  In a modification, a mixture of organic and inorganic substances, for instance of molasses and waterglass, may be added between the roasts, subsequent hardening being then unnecessary.  The Specification as open to inspection under Sect. 91, comprises also the following subject matter; the addition, between the roasts, of wholly inorganic substances, such as a mixture of waterglass and sodium aluminate, in which case the second roast may be carried out with access of air.  This subject-matter does not appear in the Specification as accepted.

Abstract: 337,088. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Aug. 7, 1929. Drawings to Specification. Gases, treating with electric discharge.-The manufacture of unsaturated hydrocarbons, particularly acetylene, and hydrogen by the electricarc treatment of gases containing saturated hydrocarbons is effected by passing the gases through a series of ares, the lengths of which are adapted to the changing composition of the gas in the sense that longer arcs are used as the concentration of hydrocarbons decreases. The acetylene may be removed after each are treatment or after a series of treatments. The initial gases may be methane, ethane, or gases containing the same, natural gases, distillation gases from coal, shale or peat, cracking gases, oil or tar vapours, or gases containing nebulized carbonaceous materials such as tar oils or coal dust. Hydrogen, nitrogen, carbon monoxide and carbon dioxide may also be present, the last three preferably only in small amounts. The process may be effected at any convenient pressure, and different pressures may be applied at different stages. An example is given in which a gas comprising methane 75 and hydrogen 25 per cent is passed through arcs of the relative lengths 4 : 5 : 6, the acetylene being removed after passage through each arc. A similar example is given in which gases from the destructive hydrogenation of coal are, passed through arcs of the relative lengths 2.86: 4: 5. Specification 294,494 is referred to.
