Abstract: The invention relates to reaction tubes provided with catalyst coated inserts whose main faces are inclined at an angle equal to or less than 10° with respect to the longitudinal axis of a reaction tube, wherein said reaction tubes enable to attain an improved yield for a hydrogen cyanide production according to a BMA process without increased sooting in the reaction tubes.

Abstract: 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.

Abstract: Proceso para la producción de cianuro de hidrógeno por el denominado proceso BMA, en el cual un hidrocarburo alifático que tiene 1 a 4 átomos C se hace reaccionar con amoníaco en presencia de un catalizador que contiene platino a 1000 hasta 1350ºC y se separa cianuro de hidrógeno del gas de reacción formado, caracterizado porque el platino del catalizador está impurificado con oro.

Abstract: The invention relates to a method for producing shaped inorganic cyanide bodies, especially made of alkaline metal cyanides and alkaline earth metal cyanides, by pressing particulate inorganic cyanide obtained by means of a crystallization method. According to the invention, a cyanide crystallate separated from a mother liquor by means of a solid-liquid separation device and containing 2-15 wt. % water is fed to a forming device without the addition of an auxiliary forming agent and placed under pressure and compressed to form shaped bodies containing 0.1-12 wt. % water. The amount of water contained by the shaped bodies is always less than that contained in the crystallates used for the production thereof. Preferably, the crystallite is pressed out of a rotary filter or a centrifuge at a temperature of more than 40° C. to form shaped bodies containing 0.2-6 wt. % residual water. The inventive method can be carried out in a more economical manner than previously known methods using dried cyanide. The invention also relates to shaped inorganic cyanide bodies obtained according to said method.
