Operating conditionsfor JZ115 series catalyst used in primary reforming and hydrogen preparation processes of commercial units

1.Inlet gas temperature of the primary reformer tube: 400～650℃
2.Outlet gas temperature of the primary reformer tube: 650～800℃,
3.Outlet pressure of the primary reformer tube:from atmosphere to 4.5Pa.
4.Steam to carbon ratio: 2.5～4.5
5. Feed gas space velocity((carbon space velocity):
1,800 ~ 2000h-1 for the large sized ammonia plants,
~1000h-1 for the medium and small sized ammonia plants
6. Content of CH4 in outlet reformed gas components:
Depending on process parameters
The above process conditions are usually employed in the primary reformer of ordinary ammonia plants and in hydrogen units.JZ115 series catalyst is adaptable to a wide range. As for a particular, selection of optimum process conditions can be made according to the desingned.
