通过沉积沉淀法与均匀沉淀法制备以坡缕石与伽马氧化铝(Palygorskite-Gamma Alumina,PG-γ-Al_2O_3)为复合载体的负载型NiO-Fe_2O_3 /PG-γ-Al_2O_3催化剂,采用了EDX、XRD、SEM、N_2等温吸附-脱附等手段对催化剂进行了表征与分析。同时利用管式炉考察了NiO-Fe_2O_3 /PG-γ-Al_2O_3催化剂在作物秸秆热解中的催化性能和再生使用寿命及抗积炭能力,并与两种单载体催化剂(NiO-Fe_2O_3 /PG,NiO-Fe_2O_3 /γ-Al_2O_3)进行了比较。结果表明,PG-γ-Al_2O_3复合载体比表面积达134.21 m~2 /g,平均孔径为39.65 nm。NiO-Fe_2O_3 /PG-γ-Al_2O_3催化剂活性组分负载均匀,分散较好且催化剂中同时存在镍铁合金与镍...

The supported NiO-Fe2O3/ Palygorskite and Gamma Alumina(NiO-Fe2O3/PG-γ-Al2O3) catalysts were prepared by deposition-precipitation and homogeneous-precipitation methods using PG-γ-Al2O3as a carrier, and different approaches including EDX, XRD, SEM and N2isothermal adsorption-desorption were used to characterize the synthetic catalysts. Meanwhile, the catalytic pyrolysis of biomass straw was conducted to test the catalytic activity, the regenerative service life and the anti-carbon capacity of NiO-Fe2O3/PG-γ-Al2O3catalyst in a tube furnace, and to compare with the catalytic pro...
