采用缙云产的天然丝光沸石(NM),经铵酸法处理制得氢型天然丝光沸石(HNM),然后用离子交换法 E,浸渍法 I 及机械混合法 M 载铂或钯,制成双功能催化剂。在加压微反色谱联合装置上进行 nC_5~0/nC_6~0异构化反应,测定催化活性。实验表明,采用离子交换法载的铂或钯的催化剂,活性最高。同时还考察了粘结剂种类,原料组成及工艺条件,如温度、空速、氢烃比和压力对催化剂活性的影响等。使用0.5%Pd/HNM-E_(43)催化剂在20mL 小试加压临氢异构化反应器上进行了稳定性试验。数据表明,E_(43)催化剂具有较高的活性和良好的稳定性、也具有良好的再生性能。
Hydrogen natural mordenite (HNM) is prepared by natural mordenite (NM) produced by Jinyun and treated with ammonium acid, then platinum or palladium is prepared by ion exchange method E, impregnation method I and mechanical mixing method to produce bis Functional catalyst. NC_5 ~ 0 / nC_6 ~ 0 isomerization reaction was carried out on a pressurized micro-chromatographic device, and the catalytic activity was measured. Experiments show that the use of ion exchange supported platinum or palladium catalyst, the highest activity. At the same time, the type of binder, composition of raw materials and process conditions such as temperature, space velocity, the ratio of hydrogen to hydrocarbon and the effect of pressure on the activity of the catalyst were also investigated. The stability test was carried out on a 20mL small test pressure hydroisomerisation reactor using 0.5% Pd / HNM-E_ (43) catalyst. The data show that E_ (43) catalyst has high activity and good stability, also has good regeneration performance.
