Abstract

A catalyst for such reaction as the oxidation of ammonia, methyl alcohol, or methane, or for the preferential combustion of carbon monoxide in presence of hydrogen by reaction with steam, is prepared by heating silver or copper cyanamide, or a mixture of these, in the presence of air to the point where puffing occurs. By incorporating a ferro- or ferricyanide, e.g. bismuth ferrocyanide, bismuth ferricyanide, calcium cerium ferrocyanide, cerium cobalt ferrocyanide, vanadium ferrocyanide, or molybdenum ferrocyanide, with the starting material, an activated product is obtained. The silver and copper cyanamides are prepared by precipitating a dissolved cyanamide with silver nitrate and cupric chloride respectively; the calcium cerium ferrocyanide is obtained by adding calcium ferrocyanide to cerium chloride solution; and cerium cobalt ferrocyanide is prepared by the interaction of cerium chloride, potassium ferrocyanide, and a soluble cobalt salt.ALSO:A catalyst for the oxidation of methyl alcohol or methane to formaldehyde is prepared by heating silver or copper cyanamide, or a mixture of them, in the presence of air to the point where puffing occurs. By incorporating a ferro- or ferri-cyanide, e.g. bismuth ferrocyanide, bismuth ferricyanide, calcium cerium ferrocyanide, cerium cobalt ferrocyanide, vanadium ferrocyanide, or molybdenum ferrocyanide, with the starting material, an activated product is obtained.ALSO:Silver and copper cyanamides are prepared by precipitating a dissolved cyanamide with silver nitrate and cupric chloride respectively; calcium-cerium ferrocyanide is obtained by adding calcium ferrocyanide to cerium chloride solution; and cerium-cobalt ferrocyanide is produced by the interaction of cerium chloride, potassium ferrocyanide and a soluble cobalt salt, such as cobalt chloride.
