| 英文摘要 | Rh, Mn and Li were supported on SBA-15 samples that had been calcined at 550, 700, 800, and 900 degrees C, using an incipient co-impregnation technique. The catalytic performances of these materials were subsequently evaluated for the hydrogenation of carbon monoxide. The catalysts were characterized by means of N-2 adsorption-desorption, X-ray diffraction, transmission electron microscopy, H-2 chemisorption, and Fourier transform infrared spectroscopy. The structure of the SBA-15 support remained unchanged even after its calcination at 900 degrees C. However, the specific surface area, pore size, and total pore volume of SBA-15 decreased from 842.6 m(2). g(-1), 9.57 nm, and 1.18 cm(3).g(-1) to 246.4 m(2). g(-1) 5.62 nm, and 0.34 cm(3).g(-1), respectively, when the calcination temperature increased from 550 to 900 C. In addition, the Rh particle size increased in the range of 1.5-4.0 nm with increasing calcination temperature. Furthermore, the Rh particles showed a greater tendency towards the mesopores of support when they were calcined at high temperatures, which could be attributed to the reduced number of micropores. These changes therefore made it easier for H2 and CO to interact with the Rh particles immobilized on the supports calcined at high temperatures. High levels of activity and selectivity towards C2+ oxygenates were therefore obtained on the Rh-Mn-Li/SBA-15 prepared using the SBA-15 calcined at 900 degrees C. |
