摘　　要：由洛阳石油化工工程公司工程研究院开发的降低催化裂化再生烟气中氮氧化物含量的助剂LDN 1在中国石油天然气股份有限公司独山子石化分公司催化裂化装置上得到了成功应用 ,结果表明 :该助剂能够显著降低再生烟气中NOx 含量并具有良好的CO助燃功能 ,在催化裂化主催化剂中加入质量分数为 3 %左右的LDN 1助剂 ,可使再生烟气中的NOx 质量浓度从 14 0 0mg/m3降至 3 3 0mg/m3,NOx 脱除率达 75 %。同时不会对产品分布和产品性质产生不良影响。LDN-1developed by Research Institute of Petrochemical Engineering Technology / LPEC for decreasing NO x content in FCC unit regenerator flue gas has been successfully applied in the FCC unit of Dushanzi Petrochemical Company. The results showed that NO x content in flue gas has been evidently decreased with LDN-1 and the assistant has an excellent performance of CO combustion promoting. NO x content in the regenerator flue gas has been decreased from 1 400 mg/m 3 to 330 mg/m3 when about 3% LDN-1 was added into the catalyst inventovy. NO x removal rate has reached 75% without negative effect on product slate and properties.
