Embodiment 1
[0033] A: Carrier pretreatment
[0034] First, a certain particle size of Al 2 o 3 The carrier was dried at 120°C for 3 hours, and placed in a desiccator for later use.
[0035] B: Preparation of precursor solution
[0036] Prepare 0.4g / ml Fe(NO 3 ) 3 9H 2 O solution.
[0037] C: Preparation of Adsorbent
[0038] Weigh 10g of pretreated γ-Al 2 o 3 Carrier in the crucible, measure 1.90ml Fe(NO 3 ) 3 9H 2 O was diluted with 11.10ml of distilled water and stirred evenly. Evenly added to the γ-Al 2 o 3 carrier crucible. Dry in the air for 10h, dry at 100°C for 12h, and roast at 500°C for 2h to obtain the adsorbent 3wt% Fe 2 o 3 / γ-Al 2 o 3 .
[0039] The prepared adsorbent 3wt% Fe 2 o 3 / γ-Al 2 o 3 Placed in a fixed bed reactor, reaction gas composition: 0.03vol% H 2 S, 60μg / m 3 Hg, 5vol%H 2 , 5vol% CO, 5vol% CO 2 , balance gas N 2 , the reaction volume space velocity is 5000h -1 , respectively at 100°C, 150°C, and 200°C for activity evaluation. When...
Embodiment 2
[0041] A: Carrier pretreatment
[0042] With embodiment 1.
[0043] B: Preparation of precursor solution
[0044] Prepare 0.1g / ml Pd(NO 3 ) 3 2H 2 O solution.
[0045] C: Preparation of Adsorbent
[0046] Weigh 10g of pretreated γ-Al 2 o 3 The carrier is placed in a crucible, and 2.00ml of Pd(NO 3 ) 2 2H 2 O was diluted with 11.00ml of distilled water and stirred. Evenly added to the γ-Al 2 o 3 carrier crucible. Air-dry for 10 hours, dry at 100°C for 12 hours, and bake at 500°C for 2 hours. Prepared Adsorbent 1wt%PdO / γ-Al 2 o 3 . The prepared adsorbent 1wt%PdO / γ-Al 2 o 3 Placed in a fixed bed reactor, reaction gas composition: 0.07vol% H 2 S, 80μg / m 3 Hg, 10vol%H 2 , 20vol% CO, 5vol% CO 2 , balance gas N 2 , the reaction volume space velocity is 5000h -1 , Activity evaluation was carried out at 100°C, 200°C, and 300°C, respectively. When the reaction temperature is 300°C and the reaction time is 400min, the mercury removal rate is 50%, the mercury cap...
Embodiment 3
[0048] A: Carrier pretreatment
[0049] Same as Example 1
[0050] B: Preparation of precursor solution
[0051] Prepare 0.4g / ml Fe(NO 3 ) 3 9H 2 O solution and 0.1 g / ml Pd(NO 3 ) 3 2H 2 O solution.
[0052] C: Preparation of Adsorbent
[0053] Weigh 10g of pretreated γ-Al 2 o 3 Carrier in the crucible, measure 1.90ml Fe(NO 3 ) 3 9H 2 O was diluted with 11.10ml of distilled water and stirred evenly. Evenly added to the γ-Al 2 o 3 carrier crucible. Air-dry for 10 hours, dry at 100°C for 12 hours, and bake at 500°C for 2 hours. Produced 3wt% Fe 2 o 3 / γ-Al 2 o 3 Adsorbent. Then measure 2.00ml Pd(NO 3 ) 2 2H 2 O was diluted with 11.00ml distilled water and stirred evenly. Uniformly added to the 3wt% Fe prepared above 2 o 3 / γ-Al2 o 3 In the adsorbent, air dry for 10 hours, dry at 100°C for 12 hours, and bake at 500°C for 2 hours. Prepared adsorbent 1wt%PdO3wt%Fe 2 o 3 / γ-Al 2 o 3 . The adsorbent prepared above is placed in a fixed-bed reactor, a...
