PROCESS OF STEAM CATALYTIC REFORMING OF HYDROCARBON FEEDSTOCK Russian patent published in 2005 - IPC

FIELD: petroleum processing.

SUBSTANCE: hydrocarbon/steam mixture is subjected to preliminary reforming stage in contact with first steam reforming catalyst enclosed within externally heated preliminary reforming reactor in passage for furnace gas escaping from steam reforming reactor with flame heating. Stream subjected to preliminary reforming and escaping from preliminary reforming reactor comes into contact with second steam reforming catalyst enclosed within steam reforming reactor with flame heating. Process may further comprise stage wherein stream subjected to preliminary reforming interacts with third reforming catalyst disposed outside of furnace gas passage between preliminary reforming reactor outlet (in furnace gas passage) and inlet of steam reforming reactor with flame heating.

EFFECT: prolonged undisturbed process period.
