The heat and weight change of MFI zeolite powders during its calcination process was investigated by DSC and TGA, respectively, in order to optimize the calcination procedure of MFI zeolite membrane.
并且利用热重和差热分析研究了MFI沸石在焙烧过程中的热重变化性质,以此确定了沸石膜的焙烧程序。
That the calcination process will change the graininess, dispersity and acidity-basicity of the catalyst can explain the discrepancy of the above phenomena.
