Title (EN) METHOD FOR PRODUCING HYDROGEN CYANIDE
(FR) PROCÉDÉ DE PRODUCTION DE CYANURE D'HYDROGÈNE
Abstract: front page image
(EN)In a method for producing hydrogen cyanide by passing a feed mixture comprising ammonia and methane through reaction tubes, coated on the inner surface with a catalyst comprising platinum, at a reaction temperature of 1000°C to 1400 °C, operated for a time period of at least 100 h, the concentration difference between the ammonia concentration and the methane concentration in the product gas mixture is maintained in a range of from 1.05 % by volume to 3.0 % by volume for at least 80% of the time.
(FR)Dans un procédé de production de cyanure d'hydrogène par passage d'un mélange d'alimentation comprenant de l'ammoniac et du méthane à travers des tubes de réaction, revêtue sur la surface interne d'un catalyseur comprenant du platine, à une température de réaction de 1000 °C à 1400 °C, fonctionnant pendant une période de temps d'au moins 100 h, la différence de concentration entre la concentration d'ammoniac et la concentration en méthane dans le mélange gazeux produit est maintenu dans une plage allant de 1,05 % en volume à 3,0 % en volume pendant au moins 80 % du temps.
