Influence of Nickel Loading and the Synthesis Method on the Efficiency of Ni/TiO2 Catalysts for Renewable Diesel Production
نویسندگان
چکیده
The efficiency of Ni/TiO2 catalysts for renewable diesel production was evaluated in the present study. Two series were synthesized and characterized using various physicochemical techniques (N2 physisorption, XRD, SEM, XPS, H2-TPR, NH3–TPD). In first catalysts, successive dry impregnations (SDI) used depositing 10, 20, 30, 50, 60 wt.% Ni. yield towards is maximized over catalyst with 50 Ni loading. Selecting this optimum loading, a second via three additional preparation methods: wet impregnation (WI) deposition–precipitation either ammonia (DP-NH3) or urea (DP-Urea) as precipitation agent. catalysts’ green influenced by method following order: DP-Urea > DP-NH3 WI ≈ SDI. metallic surface area balanced acidity mainly determine performance catalysts.

phatic communion is a cultural concept which differs across cultures. according to hofstede (2001), the u.s. tends to have individualistic culture; however, asian countries tend to have collectivistic cultures. these cultures view phatic communion differently. in individualistic cultures like u.s., phatic communion reflects speakers’ socio-cultural relationships in conversations. to see whether...
