(FR2745806-A1)      A process for the catalytic cracking of ammonia present in a fluid containing hydrogen sulphide, is claimed.The fluid is passed into a reaction zone heated to 1000 - 1400C. containing an appropriate catalyst and a cracked effluent is obtained.The reaction zone is heated by electrical heaters or by thermal exchange distributed in the interior of the reaction zone.    USE -   The invention comprises a process and apparatus (F) for the cracking of ammonia in a gaseous or liquid fluid containing hydrogen sulphide, and a subsequent application, in an integrated process, for the elimination of hydrogen sulphide in a Claus unit.    ADVANTAGES -   The process enables the selective cracking of ammonia in the presence of hydrogen sulphide and obviates the use of procedures which involve their elimination, by incineration, in the form of ammonium sulphide which produces sulphur dioxide harmful to the environment.
