Evaluating and understanding the hydrothermal stability of alumina aerogel doped with yttrium oxide and used as a catalyst support for the thermo-catalytic cracking (TCC) process.(Report)
|
Abstract: The current work presents results concerning the hydrothermal stability of yttria-doped alumina aerogel, which was prepared by the sol-gel method using a supercritical drying technique. The influence of atmospheric steam at 750 and 1000 [degrees]C on the rate of sintering of yttria-doped alumina aerogel with various yttria contents was investigated. BET N2 adsorption measurements, X-ray diffraction, thermogravimetric analysis, FTIR of adsorbed pyridine, and [1.sup.H] and [27.sup,Al] MAS NMR were used for characterization of solid samples. It was found that the ...
