摘　　要：以焦炉煤气为原料气,在实验室中对络合铁催化剂进行适应性研究,分析了络合铁催化及脱除H2S机理。并在焦化企业脱硫装置进行了工业试用,考察了p H、氧化还原电位、再生空气量对脱硫过程的影响,结果表明,在使用了络合铁催化剂后,焦炉煤气中硫化氢含量从2.0~4.0 g/m^(3)降到20 mg/m^(3)以下,脱硫装置运行稳定,无脱硫废液排出。Using coke oven gas as feedstock gas,the adaptability of complex iron catalysts is studied in laboratory.Catalytic mechanism of complex iron catalyst and H2 S removal mechanism over it are analyzed. Its industrial trial is conducted in a desulfurization unit of a coking enterprise. The influences of PH,redox potential,and air volume for regeneration on the desulfurization process are investigated. It is shown that the content of H2 S in coke oven gas drops from 2. 0-4. 0 g·m^(-3) to below 20 mg·m^(-3) after the use of complex iron catalyst,the desulfurization unit runs stably and there is no discharge of desulfurization waste liquid.
