REDUCED GENERATION OF AMMONIA IN NICKEL CATALYST OF REFORMER
Reformation of natural gas without excessive production of ammonia, even if the natural gas includes as much as 14% nitrogen, is achieved in reformers including tubes (75) having outer chambers (78) with catalysts therein, a first stage (80) of catalyst having between about 10% and about 25% nickel,...

| description | Reformation of natural gas without excessive production of ammonia, even if the natural gas includes as much as 14% nitrogen, is achieved in reformers including tubes (75) having outer chambers (78) with catalysts therein, a first stage (80) of catalyst having between about 10% and about 25% nickel, a second stage (81 ) of catalyst having less than 10% nickel, and a final stage (82) having 2% or less rhodium catalyst of a low concentration.
Selon l'invention, le reformage de gaz naturel sans production excessive d'ammoniac, même si le gaz naturel comprend jusqu'à 14 % d'azote, est réalisé dans des reformeurs comprenant des tubes (75) comportant des chambres externes (78) contenant des catalyseurs, un premier étage (80) de catalyseur ayant entre environ 10 % et environ 25 % de nickel, un deuxième étage (81) de catalyseur ayant moins de 10 % de nickel et un étage final (82) ayant 2 % ou moins de catalyseur au rhodium d'une faible concentration. |
