Activity and carbon formation resistance of the prepared catalysts were evaluated under various reaction conditions. Catalyst characterizations with TG, TPR and H2 chemisorption were carried out to investigate the promoting mechanism. Experimental results show that rare-earth promoters, especially Yb promoter, obviously improve the activity and carbon formation resistance of Ni/γ-Al2O3 catalyst, and Yb-Ni catalyst shows even higher performance than several commercial catalysts. According to the characterization results, Yb promoter enhances the interaction between the active metal and support, thus increasing the active metal's dispersion and improving its performance. Furthermore, the obvious difference in diesel conversion between Yb-Ni catalyst and others was shown in the temperature range of 450-550 °C, which would be the reason for its excellent carbon resistance.展开更多

Both sets of catalysts were synthesized via a wet co-impregnation procedure. Physicochemical characterization of the catalysts showed that the promoted catalyst possessed smaller metal crystallite size, hence higher metal dispersion compared to the virgin Ni/Al2O3catalyst. This was also corroborated by the surface images captured by the FESEM analysis. From temperature-programmed calcination analysis, the derivative weight profiles revealed two peaks, which represent a water elimination peak at a temperature range of 373 to 473 K followed by nickel nitrate decomposition from 473 to 573 K. In addition, BET surface area measurements gave 85.0 m2 g-1for the non-promoted Ni catalyst, whilst the promoted catalysts showed an average of 1% to 6% improvement depending on the La loadings. Significantly, reaction studies at 873 K showed that glycerol dry reforming successfully produced H2. The 2%La-Ni/Al2O3catalyst, which possessed the largest BET surface area, gave an optimum H2generation(9.70%) at a glycerol conversion of 24.5%.展开更多

President Xi Jinping, during his term of office in Zhejiang, launched a number of seminars and activities to seek "a Zhejiang spirit that moves with the times." Forty years of reform and opening-up, the "Zhejiang spirit" has experienced an evolution that can be summarized as three improvements: from spontaneous formation to deliberate cultivation, from something limited to eastern Zhejiang to an integrating force that spans the entire Zhejiang Province, and from a mere existence to a role that functions adequately. The "Zhejiang spirit" is extracted from the humanistic spirits shaped in all corners of Zhejiang province. It is "an instrumental ensemble played across the entire province," and represents a certain judgment and interpretation. The "Zhejiang spirit" not only describes and summarizes the past and present, but will also guide and motivate the future, and support people in their enterprising and industrious practices to move with the times.展开更多
