Abstract
A process is described for the catalytic cracking of ammonia present in a fluid containing hydrogen sulphide, in which the fluid is introduced into a reactor comprising a suitable catalyst and a catalytic cracking effluent is recovered. The temperature in the reaction zone is 1000.degree. C. to 1400.degree. C. and a reactor for carrying out the process comprises at least one heating chamber (3, 4) and at least one catalysis chamber (11) in which the ammonia is cracked without cracking the hydrogen sulphide. In a further variation, the reactor comprises at least one catalyst in the spaces defined between the heating elements.
