METHOD FOR REFORMING HYDROCARBON WITH STEAM

摘要: PURPOSE:To reduce the thermal load required in a high temp. steam reforming stage by utilizing remaining heat of flue gas for preheating methane-rich fed from low reformer to reformer. CONSTITUTION:In insulated 3, hydrocarbon and superheated as starting materials contact with 1st catalyst under conditions produce contg. H2, CO, CO2 unreacted steam. The flowing out 3 is preheated indirect 6 heating furnace 5 which an external system 4 has been installed, 4. In 4, contacts 2nd H2-rich >= about 50mol% H2.
