Zusammenfassung:Process for the production of a H 2 -containing product in a hydrogen production facility comprising a catalytic steam-hydrocarbon reformer and a pressure swing adsorption unit. The process comprises a catalytic steam-hydrocarbon reformer shutdown mode, a pressure swing adsorption unit shutdown mode, a pressure swing adsorption unit maintenance state, a pressure swing adsorption unit startup mode, and a catalytic steam-hydrocarbon reformer startup mode. The pressure swing adsorption unit startup mode comprises purging the adsorption beds with N 2 , then purging the adsorption beds with H 2 , and then adjusting the pressure of the H 2 in the adsorption beds to within defined target pressure ranges.
