Embodiment 1
[0035] as attached figure 1 As shown, the whole device includes: flow controller (1), air inlet duct (2-i), inert gas duct (2-ii), base (3), microporous aeration head with bubble diameter less than 2mm (4) , stainless steel reaction column (5), heating cable (6), 8 modified nanometer zero-valent iron units (7), insulation layer (8), and air outlet duct (9).
[0036] The flow controller (1) is located at the inlet duct (2-i); the base (3) is located at the bottom of the stainless steel reaction column (5); the diameter of the stainless steel reaction column (5) is 10-20 cm, The height of the reaction column is 2.0~8.0 m, and the height:diameter ratio of the reaction column is ≥20; the air inlet duct (2-i) passes through the base (3) and is connected to the microporous aeration head (4); the inert gas duct (2-ii) After passing through the base (3), it is connected to the microporous aeration head (4); the microporous aeration head (4) is connected to the air inlet at the botto...
Embodiment 2
[0042]In Example 2, the preparation method of modified nano-zero-valent iron described in Example 1 was replaced by: placing 100 g of nano-zero-valent iron with a particle size of 150-200 nm in 500 mL of deoxygenated aqueous solution for ultrasonic treatment Afterwards, centrifuge the obtained. Ultrasonic treatment time is 2 h; ultrasonic treatment adopts pulse mode; ultrasonic frequency is 20 kHz; ultrasonic reaction temperature is 40 ℃; ultrasonic amplitude is 120 μm; The time is 2 seconds. The composition of the mixed gas containing hydrogen sulfide is changed to: the content of hydrogen sulfide is 15%, the content of nitrogen is 70%, and the content of carbon monoxide is 15%. Use 2 Nano ZVI units. Before the reaction, an argon purging device was used to control the reaction temperature at 340 °C, and the volumetric space velocity of hydrogen sulfide to nano-zero-valent iron was 600-800 h -1 , other conditions remain unchanged, until the reaction is saturated, a product ...
Embodiment 3
[0044] In Example 3, the preparation method of modified nano-zero-valent iron described in Example 1 was replaced by: placing 100 g of nano-zero-valent iron with a particle size of 200-250 nm in 500 mL of deoxygenated aqueous solution for ultrasonic treatment Afterwards, centrifuge the obtained. Ultrasonic treatment time is 1 h; ultrasonic treatment adopts pulse mode; ultrasonic frequency is 20 kHz; ultrasonic reaction temperature is 50 ℃; ultrasonic amplitude is 90 μm; The time is 3 seconds. The composition of the mixed gas containing hydrogen sulfide is changed to: the content of hydrogen sulfide is 20%, the content of nitrogen is 60%, and the content of carbon monoxide is 20%. Uses 5 nanometer zero valent iron units. A helium gas purging device was used before the reaction, the reaction temperature was controlled at 400 °C, and the volumetric space velocity of hydrogen sulfide to nano-sized zero-valent iron was 800-1300 h -1 , other conditions remain unchanged, until the...
