Publication number: 20240166504Abstract: The present invention concerns a process and apparatus for cracking ammonia gas at super-atmospheric pressure in catalyst-filled reactor tubes in a furnace. The tubes each have an upstream layer of a first catalyst and a downstream layer of a second catalyst, the first catalyst being more active than the second catalyst. Having the more active catalyst upstream reduces the temperature of the outer walls of the tubes in the region of the burner flames and the temperature of the inner walls of the tubes in the region with the highest mole fraction of ammonia. Nitriding of the metal of the tubes in this region is thereby reduced.Type: ApplicationFiled: November 21, 2022Publication date: May 23, 2024Applicant: Air Products and Chemicals, Inc.Inventors: Andrew Shaw, Simon Craig Saloway

Publication number: 20240166503Abstract: The invention concerns a process and apparatus for cracking ammonia in which heated ammonia gas at super-atmospheric pressure is partially cracked in at least two adiabatic reactors in series with interstage heating in which the feed temperature to a first reactor is higher than the feed temperature to a further reactor to produce a partially cracked ammonia gas which is then fed to catalyst-containing reactor tubes in a furnace to produce a cracked gas comprising hydrogen gas, nitrogen gas and residual ammonia gas. The use of the adiabatic reactors enables more efficient heat integration within the process and the higher temperature in the first reactor enables the use of a nickel-based catalyst in that reactor as an alternative solution to the potential problem of the presence of oil in the ammonia.Type: ApplicationFiled: November 21, 2022Publication date: May 23, 2024Applicant: Air Products and Chemicals, Inc.Inventors: Vincent White, Andrew Shaw, Simon Craig Saloway
