以ZSM-5和β沸石为原料,在N,N-二乙基-顺式-2,6-二甲基哌啶氢氧化物(DMPOH)存在下,在水热条件下成功地合成了硅铝分子筛SSZ-39。在NH3-SCR选择性催化还原NOx反应中的催化性能测试表明,通过分子筛间转化合成的铜交换产物具有良好的催化性能。
Aluminosilicate SSZ-39 zeolite has been successfully prepared by transformation from ZSM-5 and beta zeolite in the presence of N,N-diethyl-cis-2,6-dimethylpiperidinium hydroxide (DMPOH) under hydrothermal conditions. Catalytic tests in the selective catalytic reduction of NOx with NH3 (NH3-SCR) show that the copper-exchanged products synthesized from the interzeolite transformation exhibit excellent catalytic performance.
