主 题:CO2reforming glycerol lanthanum longevity syngas
摘 要:This paper reports on the longevity of glycerol-dry(CO2) reforming over the lanthanum(La) promoted Ni/Al2O3 *** XRD results showed that the Ni particle was well-dispersed in the presence of La *** addition,via the NH3-TPD analysis,it was found that the La promoter has reduced the acidity of Ni catalyst which may have explained the mitigation of carbon *** was determined that the 3.0 wt% La-promoted Ni/Al2O3 catalyst possessed the largest BET specific surface area of 97 m2 ***,it yielded the best catalytic longevity performance with conversion attained more than 90%,even after 72 h of reaction ***,it can be confirmed that the presence of CO2 during the glycerol dry reforming was essential in reducing carbon deposition,most likely via gasification *** has ensured a stability of catalytic activity for a long reaction period(72 h).
