| titleOfInvention | A kind of preparation method of Ce modified Cu-Fe-SSZ-13 molecular sieve |
| abstract | The present invention relates to a kind of preparation method of Ce-modified Cu-Fe-SSZ-13 molecular sieve, be specifically related to slowly drop tetraethylenepentamine in the copper sulfate solution under vigorous stirring, add cerium nitrate and ferric nitrate successively after reaction finishes, Mix well and add sodium hydroxide to prepare liquid A; add sodium metaaluminate or aluminum sulfate octadecahydrate to liquid A, stir for 1-2 hours, then add silica sol, continue stirring for 2-3 hours, and place put into a polytetrafluoroethylene-lined steel reactor, and age for 12 to 14 hours. The obtained sol-gel precursor was subjected to a homogeneous hydrothermal reaction at 120 to 180°C for 72 to 96 hours. After crystallization, solidified The liquid is separated, the solid is washed with water until the pH is neutral, and then dried, and then the solid is calcined at 500-550° C. for 4-8 hours to obtain a Cu-Fe-Ce-SSZ-13 molecular sieve. |
