采用水热法合成出金属有机骨架化合物[Cu2(OH)(2,2’-bipy)2(BTC)·2H2O]n晶体,以此化合物为吸附剂,在常温常压下通过固定床动态吸附实验,考察了其对模型油中的噻吩和苯并噻吩的脱除效果。结果表明,该吸附剂对噻吩、苯并噻吩的饱和吸附容量分别为2.32%,1.20%;采用4 A分子筛与吸附剂分层装填的方法可有效解决模型油中的溶解水对吸附脱硫效果的影响;用甲苯对吸附饱和的吸附剂进行再生,再生率达到98%。
Hydrothermal synthesis of metal organic framework compounds [Cu2 (OH) (2,2’-bipy) 2 (BTC) · 2H2O] n crystals, as the compound as an adsorbent, at room temperature under normal pressure through a fixed bed dynamic adsorption The effects of thiophene and benzothiophene on the model oils were investigated. The results showed that the adsorption capacity of the adsorbent for thiophene and benzothiophene was 2.32% and 1.20%, respectively. Adopting the 4 A molecular sieve and the adsorbent layered packing method, the adsorption capacity of the model oil in the adsorptive desulfurization could be effectively solved Effect; using toluene adsorption of adsorbent for regeneration, the regeneration rate of 98%.
