Embodiment 1
[0077] The CO in the unreacted gas of the present invention can be as high as 85% or more, and the CO in the shifted gas can be reduced to 0.4%. The shift reactor catalyst is a sulfur-resistant cobalt-molybdenum catalyst composed of MOS and COS. The temperature of the catalyst bed in the present invention is within the low-end range of the active temperature (230°C- 310°C), the maximum temperature difference between the axial and radial directions of the reaction bed is only within 3°C to 8°C.
[0078] The isothermal shift reactor 5 is cylindrical as a whole, such as image 3 As shown, by upper tube plate 2, charging tube 3, lower tube plate 4, double sets of water vapor pipes 5, shell 6, upper radial catalytic bed 7, center pipe 8, U-shaped water vapor pipe 9, annular communicating hole 10, The support head 11, the steam-water mixture nozzle 12, the lower radial catalytic bed 13, the upper discharge pipe 14, the lower discharge pipe 15, the sealing packing 16, the bottom tee...
Embodiment 2
[0090] Such as Figure 4 As shown, the CO volume concentration matched with the isothermal shift reactor of the present invention is 40% to 70%, and the gas shift process flow of water-gas ratio is 1.3 to 1.6, which consists of the first water separator E-41, the heat exchanger E -42, purification and detoxification devices E-43, E-44, isothermal shift reactor E-45, first waste heat boiler E-46, second waste heat boiler E-47, second water separator E-48, Boiler feed water heater E-49, water cooler E-410, third water separator E-411. During operation, the coal containing CO passes through the first water separator E-41 and enters the heat exchanger E-42. The unreacted gas is heated to 230°C-240°C and enters the purification and detoxification devices E-43, E-44, Chlorine, phosphorus, oxygen, and hydrocarbons in the gas are removed here, and a small amount of CO is also converted. After the gas temperature rises to 255 ° C ~ 265 ° C, it enters the isothermal shift reactor E-45,...
Embodiment 3
[0093] Such as Figure 5 As shown, the CO 50%-85% industrial furnace gas (such as acetylene furnace gas, steelmaking converter, yellow phosphorus furnace gas) conversion process flow matched with the isothermal shift reactor of the present invention.
[0094] Industrial furnace gas is characterized by high C0% content (40% to 85%), basically no water vapor, basically no sulfur, but high dust content, high oxygen content, and acetylene furnace gas also contains unsaturated hydrocarbons.
[0095] Such as Figure 5 As shown, the isothermal transformation process is used to match the process by E-51 washing tower, E-52 water separator, parallel filters E-53, E-54, compressor E-55, oil remover E-516, purification and removal Poison E-56, E-57, Hydrogenation Converter E-517, Isothermal Shift Reactor E-58, Steam Dryer E-59, Heat Exchanger E-510, Boiler Desalination Water Heater E-511, Desalination Composed of oxygen water heater E-512, air cooler E-513, fifth water separator E-514,...
