| 英文摘要 | The effect of thermal pretreatment on the bifunctional NiW catalyst and its hydrodeoxygenation (HDO) performance on oleic acid were investigated. Increasing the calcination temperature (CT) not only led to the growth of NiW particles, but caused the migration of Ni to the surface that resulted in the segregation of W. The reduction temperature (RT) was also able to tune the catalyst surface composition. A lower RT (600 degrees C) led to a W-rich surface, while a higher one (700 degrees C) interestingly resulted in a Ni-rich surface. To this end, the ratio of surface-active sites, i.e., the partially reduced W species (W delta+) to Ni0 ones (W delta+/Ni0), was manipulated. The highest W delta+/Ni0 ratio of 2.6 was reached at the CT and RT of 550 degrees C and 700 degrees C, respectively, which contributed to an impressively high solvent-free deoxygenation of 95.1% at only 300 degrees C. The deoxygenation rate (rdeoxy.) was much higher than that of the reported non-precious catalysts, even comparable to the precious ones. Additionally, a high catalyst durability was found on non-acid feedstocks like triglycerides, long-chain alcohols, etc., but an acidic substrate like oleic acid tended to leach the loaded metals that eventually lessened the HDO activity. |
