Abstract:
A process for synthesis of hydrogen cyanide according to the BMA process wherein a shaped ceramic molded body is produced by a process comprising uniformly wetting a ceramic molded body with a coating dispersion which contains at least one particulate elemental platinum group metal and a particulate nitride of an element selected from the group consisting of aluminum, boron, titanium, silicon and mixtures thereof as cation in a vaporizable carrier liquid, evaporating the carrier liquid and converting the coating into the catalytically active state by slowly heating to 1000 to 1350.degree. C. in the presence of nitrogen and/or ammonia, wherein said particulate nitride and said platinum group metal have an average particle size of less than 100 .mu.m, and said shaped ceramic body is used as a catalyst to synthesize hydrogen cyanide from hydrocarbons and ammonia according to the BMA process.
