 Promoting hydrogen-rich syngas production through catalytic cracking of rape straw using Ni-Fe/PAC-γAl2O3 catalystXunwang Shi, Kaidi Zhang, Qunpeng Cheng, Guangsen Song, Guozhi Fan and Jianfen Li Renewable Energy, 2019, vol. 140, issue C, 32-38 Abstract: A catalyst loaded Ni-Fe using powder active carbon (PAC) and γ-Al2O3 as the support was prepared for hydrogen-rich syngas production from rape straw pyrolysis in a two-stage fixed reactor. EDX (Energy-dispersive X-ray spectroscopy), SEM (Scanning electron microscope) and N2 isothermal adsorption-desorption were used to characterize the catalysts. The results showed that the support of PAC-γAl2O3 was uniform with large specific surface area. The metals loaded on the support were well dispersed. The performance of Ni-Fe/PAC-γAl2O3 catalysts compared with single support catalyst NiO-Fe2O3/γAl2O3 (NFA) and NiO-Fe2O3/PAC (NFP) was studied. The results showed that the Ni-Fe/PAC-γAl2O3 catalysts showed a good catalytic activity which obviously enhanced the H2 gas yield to 54.23 g/kg Rape straw and reduced the tar yield to 4.06 g/kg. Meanwhile, Ni-Fe/PAC-γAl2O3 catalysts had a stronger ability to prevent the deactivation to keep a longtime stability than the single carrier catalyst.
