Abstract
The present invention relates to a reactor (201) for preparing hydrogen cyanide by the Andrussow process, to an equipment (200) comprising said reactor and to a process for preparing hydrogen cyanide by the Andrussow process. The reactor (201) comprising at least one gas inlet (I) for reactant gases mixture, a catalyst (203), a porous support for the catalyst (204), a porous sub support (205, 206) and at least one outlet (P8) for the reaction products. According to the invention, said reactor has a cone frustum shaped metallic casing (210) and comprises inside the metallic casing, a gas distributor (202) located between the gas inlet and the catalyst, said distributor comprising at least one cone frustum element (D1, . . . Dn) having an upper base directed towards the gas inlet (I).
