摘　　要：以氨作碱源的焦炉煤气氧化法脱硫近年来在焦化企业获得广泛应用。通过详细分析温度、催化剂等影响脱硫率的关键因素,得出欲提高脱硫率须实现过程低温化并选择性能优良的脱硫催化剂。在此过程中,采用制冷水和间接横管冷却器,可保证过程低温化的实现。The desulfurization of the coke oven gas using ammonia as alkali cannot meet the national environmental protection demand,and this hampers its development to a great extent.The factors(temperature,catalyst,etc.) that impact the desulfurization effect were analyzed,and the result shows that to increase the desulfurization result,low temperature process should be realized and optimal catalyst for desulfurization should be selected.And to realize low temperature pro-cess,chilled water and horizontal water-tube cooler should be adopted.
