Method for hydrogen production using rotating packed bed

1. A method for hydrogen production comprising

1) preparing a hydrogen producing device comprising

(a) an inlet comprising

a preheater;

(b) a reactor comprising

a tank;

a rotating packed bed comprising

an inner ring;

an outer ring; and

a catalyst bed forming at least one catalytic channel communicating with the inner ring and the outer ring and comprising

 a catalyst;

(c) an annular heating unit for heating and controlling the temperature of the tank of the reactor;

(d) a rotation controller for controlling the rotation of the rotating packed bed and comprising

a rotary motor; and

(e) an outlet is communicated with the rotating packed bed;

2) using hydrogen to wash the device and to test the impermeability thereof;

3) initiating the preheater, the annular heating unit and the rotary motor;

4) adjusting the temperature of the preheater, adjusting the temperature of the tank of the reactor and adjusting the rotating speed of the rotary motor;

5) inputting a reagent gas, a carrier gas and a liquid to the preheater while controlling the flow rates thereof so as to allow vaporization of the liquid into a steam mixed with the reagent gas, which generates a reagent mixture;

6) inputting the reagent mixture through the inlet to the tank of the reactor; and

7) passing the reagent mixture through the rotating packed bed undergoing water gas shift reaction to obtain hydrogen.

2. The method as claimed in claim 1 , wherein

in step 4), the temperatures of the preheater and the tank of the reactor are 180-550° C. and the rotating speed of the rotary motor is less than 1800 rpm.

in step 5), the reagent gas is carbon monoxide and the liquid is water.

4. The method as claimed in claim 3 , wherein

the ratio of the volumetric flow rates of the carbon monoxide and the water is from 1:1 to 1:10.

5. The method as claimed in claim 1 , wherein

in step 5), the reagent gas is a mixture of carbon monoxide gas and hydrogen gas and the liquid is water.

6. The method as claimed in claim 1 , wherein

in step 7), the reagent mixture contacts the catalyst of the catalyst bed for at least 0.01 second.

7. The method as claimed in claim 1 , wherein

the reactor further comprises

a pressure gauge; and

the outer ring is rotatable and metallic for adjusting the size of the catalyst bed by rotation of the outer ring.

8. The method as claimed in claim 1 , wherein

the annular heating unit comprises

an annular heater;

a thermo sensor;

a temperature adjuster;

a power adjuster;

a power monitor; and

a power switch.

9. The method as claimed in claim 1 , wherein

the rotation controller comprises

a base frame;

a rotating speed controller;

a tachometer;

a three-stage rotation controller; and

a motor power switch.
