| titleOfInvention | A process for the production of cyanides |
| abstract | A reactor for converting methane, ammonia and oxygen and alkaline or alkaline earth hydroxides into alkaline or alkaline earth cyanides by two-stage reactions comprising a first stage with a gas inlet (I), wherein the first stage is formed by a cone (H) with distribution plates (G) providing an even gas distribution over the catalyst material (C) wherein the distribution plates (G) are located between the gas inlet (I) of the reactor and the distribution plates (G) being perforated with a number of holes, with the distribution plates spaced from each other in the flow direction of the gas, the first distribution plate(s) (Gα) functioning mainly to distribute the gas whereas the last distribution plate (Gω) works as a heat radiation shield and as a distribution plate facing the catalyst gauze (C), and wherein the catalyst gauze (C) is present in the form of catalyst gauze(s) (C) fixed by catalyst weights (B) supports an improved process for the synthesis of HCN/NaCN by the vapor-phase reaction of ammonia, methane and oxygen followed by the absorption of the product gas by sodium hydroxide to produce sodium cyanide. The yield of HCN/NaCN may be increased by the improvement of the reactor system, to an ammonia and methane conversion of more than 75%. Typically the conversion of ammonia and methane to sodium cyanide with a reactor according to the invention is more than 90%. |
