Hydrogen production from natural gas - 3D piping diagram

Reaction principle of hydrogen production from natural gas:

(1) Steam conversion of hydrocarbons

CI4+II20→CO+3II2

- Q

CH4+2H20→C02+4H2

Q

C0+H20→C02+H2+Q

C2H6 + 2H20→2C0+ 5H2

-6

C3H8 + 3H20

3C0 + 7H2

-Q

C4II8_ +  4II20 →4C0 + 9II2

-G

C5H12+5H20-5C0+11H2 - Q

06H14+ 6H20→5C0 + 13H2 -Q

The feed gas from the reformer contains about 13.3% C0. The role of the shift is to make C0 in the catalyst

In the presence of, it reacts with water vapor to generate C02 and H2. In this way, the required raw hydrogen is increased.

(2) Medium temperature transformation

The reaction equation of medium temperature shift reaction is as follows:

C0+H20

;  C02-H2+Q
