| titleOfInvention | A kind of preparation method of Ce-modified Cu-Fe-SSZ-13 molecular sieve |
| abstract | The invention relates to a preparation method of a Ce-modified Cu-Fe-SSZ-13 molecular sieve, in particular to slowly adding tetraethylene pentamine dropwise to a copper sulfate solution under intense stirring, and adding cerium nitrate and ferric nitrate in sequence after the reaction is completed, After fully mixing, add sodium hydroxide to prepare solution A; add sodium metaaluminate or aluminum sulfate octadecahydrate to solution A, stir for 1-2 hours, then add silica sol, and continue stirring for 2-3 hours before placing The sol-gel precursor was homogeneously hydrothermally reacted at 120 to 180°C for 72 to 96 hours. After crystallization, the sol-gel precursor was cured for 12 to 14 hours. The liquid is separated, the solid is washed with water until the pH is neutral, then dried, and the solid is calcined at 500-550° C. for 4-8 h to obtain Cu-Fe-Ce-SSZ-13 molecular sieve. |
