The shortage of low-sulfur coking coal will bring about an increasingly high hydrogen sulfide (H 2 S) in the coke oven gas (COG) in the near future. This work investigated the removal of hydrogen sulfide (H 2 S) from a simulated coke oven gas (COG) by catalytic oxidative absorption in a rotating packed bed (RPB). Sodium carbonate (Na 2 CO 3) solution doped with 20 mg L− 1 of a commercial “888” catalyst was used as the absorbent. The removal efficiency of H 2 S was evaluated under various operating conditions including rotation speed of the RPB (N), liquid-gas ratio (L/G), inlet H 2 S concentration (c H 2 S, in), temperature (T) and Na 2 CO 3 concentration (c Na 2 CO 3) in an attempt to optimize the conditions. The results were validated by comparison with those of separate experiments conducted in a packed column comprising a high-efficiency laboratory packing of Dixon rings. The comparison results reveal that the RPB exhibited higher H 2 S removal efficiency than the packed column, indicating it as an efficient gas-liquid contactor with a greater potential to remove H 2 S from COG.
