PROCESS TO PREPARE A HYDROGEN AND CARBON MONOXIDE CONTAINING GAS

摘要

A PROCESS FOR THE PREPARATION OF HYDROGEN AND CARBON MONOXIDE CONTAINING GAS FROM A GASEOUS HYDROCARBON FEEDSTOCK BY PERFORMING THE FOLLOWING STEPS: @(A) PARTIAL OXIDATION OF PART OF THE FEEDSTOCK THEREBY OBTAINING A FIRST GASEOUS MIXTURE OF HYDROGEN AND CARBON MONOXIDE AND @(B) CATALYTIC STEAM REFORMING OF PART OF THE GASEOUS FEEDSTOCK IN A CONVECTIVE STEAM REFORMER COMPRISING A TUBULAR REACTOR PROVIDE WITH ONE OR MORE TUBES CONTAINING A REFORMING CATALYST, WHEREIN THE EXTERIOR OF THE TUBES OF THE TUBULAR REACTOR IS USED TO COOL THE HOT GAS A OBTAINED IN STEP (A) AND WHEREIN THE EXTERIOR OF THE TUBES IS A METAL ALLOY SURFACE COMPRISING BETWEEN 0 AND 20 WTIRON.
