| Abstract: | Zeolite is the important composition in FCC catalyst.The contents of Na2O,Al2O3,SiO2,RE2O3,etc.in the product will directly affect the quality and performance.Through the investigation of the accuracy and precision of the method,it is found that XRF is a high-efficienct,quick,high-accuracte and good-repetitional method for the determination of the contents of important oxides in zeolites;It is an analytical method that can effectively guide the production of the corporation. |
| Keywords: | XRF determination zeolite oxides |
