Embodiment 1
[0038] A method for producing hydrogen from coal, characterized in that iron or iron oxides are placed in an air reactor fluidized bed, fluidized air is introduced at the lower end A of the air reactor fluidized bed, and the operating temperature of the air reactor fluidized bed can be Controlled at about 800°C ~ 1250°C, iron or iron oxide reacts with oxygen in the air to obtain Fe 2 o 3 , and then the gas-solid two-phase is separated by the separator, and the separated air is discharged from the upper end H of the separator and can be used for power generation or waste heat utilization. The separated Fe 2 o 3 It enters the upper layer of the fuel reactor through the first overflow tank, and the operating temperature of the fuel reactor can be controlled at about 800 ° C ~ 1200 ° C. In the upper layer of the fuel reactor, some Fe 2 o 3 React with the incompletely reacted synthesis gas in the lower layer to convert to Fe 3 o 4 , and convert the synthesis gas into a carbon ...
Embodiment 2
[0040] A method for producing hydrogen from natural gas, characterized in that iron or iron oxides are placed in an air reactor fluidized bed, fluidized air is introduced at the lower end A of the air reactor fluidized bed, and the operating temperature of the air reactor fluidized bed is It can be controlled at about 800 ° C ~ 1250 ° C, and iron or iron oxides react with oxygen in the air to obtain Fe 2 o 3 , and then the gas-solid two-phase is separated by the separator, and the separated air is discharged from the upper end H of the separator and can be used for power generation or waste heat utilization. The separated Fe 2 o 3 Enter the upper layer of the fuel reactor through the first overflow tank 2, and the operating temperature of the fuel reactor can be controlled at about 800 ° C ~ 1200 ° C. In the upper layer of the fuel reactor, some Fe 2 o 3 React with the incompletely reacted gaseous fuel (natural gas or petroleum gas) in the lower layer to convert to Fe 3 o ...
Embodiment 3
[0042] A method for producing hydrogen using fuel, a device for implementing the method for producing hydrogen using fuel according to claim 1, comprising an air reactor fluidized bed 1, a first overflow tank 2, a fuel reactor 3, The second overflow tank 4, the hydrogen production reactor fluidized bed 5, and the third overflow tank 6 are composed. The upper end of the air reactor fluidized bed 1 is connected with an oxygen-deficient air separator 1-4, and an oxygen-deficient air separator 1 The lower end of -4 is connected to the upper layer 3-2 of the fuel reactor through the first overflow tank 2. The fuel reactor includes a fluidized bed, and an intermediate air distribution plate 3-3 is arranged in the fluidized bed and the intermediate air distribution plate The plate 3-3 divides the fluidized bed into the upper layer 3-2 of the fuel reactor and the lower layer 3-6 of the fuel reactor, and an overflow pipe 3 is arranged between the upper layer 3-2 of the fuel reactor and ...
