负载型磷化镍催化剂的空气表面改性法制备及其加氢脱氧性能
Preparation of supported nickel phosphide catalyst by surface modification method and its performance in hydrodeoxygenation
摘要
Abstract
With MCM-41 as support, the supported Ni2 P/MCM-41 catalyst is prepared by first reducing the Ni2 P precursors at low temperature ( 673 K ) and then modifying the surface with air; the as-prepared Ni2 P/MCM-41 catalyst was characterized by X-ray diffraction ( XRD ) , N2-sorption, scanning electron microscope ( SEM) , transmission electron microscope ( TEM) , X-ray photoelectron spectroscopy ( XPS) and CO uptake. The catalytic performance of Ni2 P/MCM-41 in hydrodeoxygenation ( HDO ) of benzofuran ( BF ) was investigated to elucidate the effect of surface modification with air on the catalyst structure and HDO activity. The results show that pure Ni2 P acts as the active phase on the surface of modified Ni2 P/MCM-41 catalyst; the surface modification can decrease the aggregation of P species and promote the formation of small and highly dispersed Ni2 P active phase. Under 573 K, 3. 0 MPa, a weight hourly space velocity of 4. 0 h-1 and a H2/oil volume ratio of 500, the yield of O-free products reaches 88% for HDO of BF over the modified Ni2 P/MCM-41 catalyst, which is about 50% higher than that over the catalyst prepared by conventional temperature-programmed reduction method.关键词
