摘要： A process for the direct preparation of alkali metal cyanide and alkaline earth metal cyanide granules from an HCN-containing gas and an aqueous solution or suspension of an alkali metal or alkaline earth metal hydroxide. The reaction is performed in a reactor for fluidized bed spray granulation, wherein a solution or suspension of the hydroxide is sprayed onto seed granules of the cyanide being prepared and at the same time a hydrogen cyanide-containing gas is supplied to the reactor and water is evaporated by means of a fluidizing gas. The preferred fluidizing gas is steam. The reaction gases from a BMA or Andrussow process may be quenched with water and the gas mixture used as fluidizing gas. By using a CO.sub.2 -free HCN-containing gas, alkali metal cyanide granules with advantageous properties, including a combined concentration of alkali metal carbonate and alkali metal formate of less then 0.4 wt. %, are obtainable.

摘要： A method of producing hydrogen cyanide by the gas-phase reaction of methane with ammonia at elevated temperature and an ammonia/methane ratio of 1.001 to 1.1. The conducting of the gaseous reaction mixture through a corona discharge causes the reaction to start at temperatures below 1000.degree. C. without the action of a catalyst. This results in considerable savings of the necessary investment expenses as well as of the running costs for energy.

摘要： The invention relates to an improvement to the BMA process for the production of hydrogen cyanide from methane and ammonia in the presence of a platinum-containing catalyst. The problem of sooting, and thus the decrease in activity, of the catalysts can be reduced, or the activity increased, in that the catalyst is doped with an element from the series Cu, Ag, Au, Pd and W. The doping is preferably in the range of 0.01 to 20 mole % doping element, based on Pt.

摘要： A process for the highly efficient production of hydrocyanic acid by reacting methane and ammonia to yield hydrocyanic acid in a reactor heated by the combustion of fuel gases and coated with a catalyst. The process is characterized in that the reactor consists of a monolithic arrangement of heating and reaction channels, wherein the fuel gas and a gas containing oxygen pass through the heating channels and the reactants pass through the reaction channels, the internal walls of which are coated with the catalyst. The fuel gas is burned in the heating channels. The monolithic structure of the reactor is such that the heating channels and reaction channels are in intimate contact. The cross-section of the channels and the wall thicknesses thereof may be reduced without any loss of mechanical stability. Wall thicknesses of 0.1 to 1 mm are completely adequate. The heating and reaction channels of the reactor may be arranged in alternating layers, wherein the axial directions of the heating and reaction channels may enclose an angle of between 0.degree. and 90.degree.. If the angle is 0.degree., the heating and reaction channels are parallel and the heating and reaction gases may pass through them co- or counter-currently.
摘要翻译：一种通过甲烷和氨反应高效地生产氢氰酸的方法，以在由燃料气体燃烧加热并涂覆有催化剂的反应器中加热产生氢氰酸。该方法的特征在于反应器由加热和反应通道的整体排列组成，其中燃料气体和含氧气体通过加热通道并且反应物通过反应通道，其内壁涂覆有催化剂。燃料气体在加热通道中燃烧。反应器的整体结构使得加热通道和反应通道紧密接触。可以减小通道的横截面和其壁厚，而不会损失机械稳定性。壁厚为0.1至1毫米完全足够。反应器的加热和反应通道可以以交替的层布置，其中加热和反应通道的轴向可以包围在0°和90°之间的角度。如果角度为0°，加热和反应通道是平行的，加热和反应气体可以共同或反向通过。
