Embodiment 1
[0025] A method for simultaneously removing hydrogen sulfide, carbonyl sulfide and carbon disulfide, specifically comprising the following steps:
[0026] (1) Clean the tobacco rods, chop them up, dry them, put them in a tube furnace, and roast them at 400°C for 1 hour under the protection of nitrogen;
[0027] (2) Grind the product of step (1) to 40 mesh, then wash it with water 4 times until the supernatant has no turbidity suspended, put it in an oven and dry it at 110°C for 5 hours;
[0028] (3) Then put it into a tube furnace, and feed CO with a flow rate of 30mL / (min g) 2 gas, roasted at 900°C for 3 hours to obtain biochar adsorbent;
[0029] (4) The biochar adsorbent prepared in step (3) is used to simultaneously remove hydrogen sulfide, carbonyl sulfide and carbon disulfide.
[0030] The adsorbent prepared in this example was tested for activity, and the activity test was carried out in a Φ3mm×100mm fixed-bed quartz reactor; the reaction conditions were: COS concentr...
Embodiment 2
[0032] A method for simultaneously removing hydrogen sulfide, carbonyl sulfide and carbon disulfide, specifically comprising the following steps:
[0033] (1) Wash, chop and dry the tobacco rods, put them in a tube furnace, and roast them at 600°C for 2 hours under the protection of nitrogen;
[0034] (2) Grind the product of step (1) to 50 mesh, then wash it with water 4 times until the supernatant has no turbidity suspended, put it in an oven and dry it at 100°C for 5 hours;
[0035] (3) Then put it into a tube furnace, and feed CO with a flow rate of 50mL / (min g) 2 gas, roasted at 600°C for 1 hour to obtain a biochar adsorbent;
[0036] (4) The biochar adsorbent prepared in step (3) is used to simultaneously remove hydrogen sulfide, carbonyl sulfide and carbon disulfide.
[0037] The adsorbent prepared in this example was tested for activity, and the activity test was carried out in a Φ3mm×100mm fixed-bed quartz reactor; the reaction conditions were: COS concentration 500...
Embodiment 3
[0039] A method for simultaneously removing hydrogen sulfide, carbonyl sulfide and carbon disulfide, specifically comprising the following steps:
[0040] (1) Clean the tobacco rods, chop them up, dry them, put them in a tube furnace, and roast them at 700°C for 3 hours under the protection of nitrogen;
[0041] (2) Grind the product of step (1) to 60 mesh, then wash it with water 4 times until the supernatant has no turbidity suspended, put it in an oven and dry it at 150°C for 2 hours;
[0042] (3) Then put it into a tube furnace, and feed CO with a flow rate of 40mL / (min g) 2 gas, roasted at 700°C for 3 hours to obtain biochar adsorbent;
[0043] (4) The biochar adsorbent prepared in step (3) is used to simultaneously remove hydrogen sulfide, carbonyl sulfide and carbon disulfide.
[0044] The adsorbent prepared in this example was tested for activity, and the activity test was carried out in a Φ3mm×100mm fixed-bed quartz reactor; the reaction conditions were: COS concentra...
