以改性白云石（Modified Dolomite,MD）为载体,利用沉积沉淀法制备了负载型NiO-Fe2O3/MD催化剂,并利用XRD、SEM、TEM、BET等手段对催化剂进行了表征和分析。同时,利用双固定床反应器对NiO-Fe2O3/MD催化剂在城市生活垃圾气化中的催化活性和使用寿命进行了评价,并与NiO/MD催化剂进行了比较。实验结果表明,NiO-Fe2O3/MD催化剂为核壳式涂层结构,表面活性颗粒粒径约为37 nm,比表面积62.48 m2/g。催化剂活性测试显示,NiO-Fe2O3/MD催化剂用于城市生活垃圾气化具有极高的催化活性,能够显著提高产品燃气品质及燃气中的H2含量,减少焦油的产生;相对于NiO/MD催化剂,其抗失活能力强,使用寿命长。

The supported NiO-Fe2O3/modified dolomite (NiO-Fe2O3/MD) catalysts were prepared by deposition-precipitation (DP)method using modified dolomite as carrier, and different approaches including XRD, SEM, TEM and BET were used to characterize the synthetic catalysts. Meanwhile, the catalytic gasification of municipal solid wastes (MSW) was conducted to test the catalytic activity and life of NiO-Fe2O3/MD catalyst in a bench-scale combined fixed bed reactor, and compared with the catalytic properties of NiO/MD catalysts. The results indicated that the prepared NiO-Fe2O3/MD catalysts had a coated co...
