NiO-Fe2O3/PG-γ-Al2O3催化剂的制备及其在秸秆热解中的应用
Preparation of NiO-Fe2 O3/ PG-γ-Al2 O3 catalysts and its application in pyrolysis of biomass straw
摘要
Abstract
The supported NiO-Fe2 O3/ Palygorskite and Gamma Alumina ( NiO-Fe2 O3/PG-γ-Al2 O3 ) catalysts were prepared by deposition-precipitation and homogeneous-precipitation methods using PG-γ-Al2 O3 as a carrier, and different approaches including EDX, XRD, SEM and N2 isothermal 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-Fe2 O3/PG-γ-Al2 O3 catalyst in a tube furnace, and to compare with the catalytic properties of single carrier catalysts. The results indicate that the prepared PG-γ-Al2 O3 carriers have a high specific surface area of 134. 21 m2/g and the average pore size is 39. 65 nm. The active components are loaded uniformly and in a good dispersion over NiO-Fe2 O3/PG-γ-Al2 O3 catalyst, meanwhile, the Ni-Fe alloy and the nickel-aluminum spinel structure exist simultaneously in the catalyst. The catalytic activity testing shows that the NiO-Fe2 O3/PG-γ-Al2 O3 catalysts have a very high catalytic activity in pyrolysis of biomass straw. It could obviously improve the quality of the gas such as the content of H2 and CO and the calorific value. The catalytic activity, regeneration effect and anti-carbon deposition ability of NiO-Fe2 O3/ PG catalyst are better than that with single carrier catalyst.关键词
