【摘要】：以硅鋁比為5.3的NaY分子篩為母體,分別采用微波輔助離子交換法(AgCeY-1)、水熱離子交換法(AgCeY-2)和液相離子交換法(AgCeY-3)制備了AgCeY-n吸附劑,并利用XRD、BET、XPS和Py-FTIR對吸附劑進行了表征。以噻吩和苯并噻吩為模型硫化物,甲苯和環(huán)己烯為競爭吸附組分,考察了制備方法對制備得到的吸附劑脫硫性能的影響。結果表明,AgCeY-n吸附劑上Ag、Ce元素分別以Ag~+、Ce~(4+)形式存在。經(jīng)微波輔助離子交換法制備得到的AgCeY-1吸附劑表面Ag~+、Ce~(4+)含量均最高,且具有最高的L酸和B酸量。AgCeY-n吸附劑對硫化物的吸附選擇大小順序為:BTTP,競爭吸附組分對AgCeY-n吸附脫硫性能的影響順序為:環(huán)己烯甲苯。在所研究的制備方法中,微波輔助離子交換法所需時間最短(20 min),合成的AgCeY-1對所研究的模擬油的吸附效果均最好,且具有較好的重復使用性能。各吸附劑對TP和BT的脫除能力大小順序為:AgCeY-1AgCeY-2AgCeY-3。
[Abstract]:The Si / Al ratio NaY 5.3 molecular sieve as precursor, respectively by microwave assisted ion exchange method (AgCeY-1), ion exchange method (AgCeY-2) and liquid phase ion exchange (AgCeY-3) AgCeY-n adsorbent was prepared, and the use of XRD, BET, the adsorbents were characterized by XPS and Py-FTIR. Thiophene and dibenzothiophene as a model compound, toluene and cyclohexene as the competitive adsorption of components, the effects of preparation methods on the prepared adsorbent for desulfurization performance. The results show that the AgCeY-n adsorption on Ag, Ce elements were Ag~+, Ce~ (4+) form was prepared by the AgCeY-1. The adsorbent surface Ag~+ by microwave assisted ion exchange, Ce~ (4+) content were the highest, and has the highest L acid and B acid.AgCeY-n adsorption sulfide on the choice of the size order is: BTTP, the competitive adsorption of the components on the AgCeY-n adsorption desulfurization performance influence order of Cyclohexene in toluene. To study the preparation method in the shortest time required for microwave assisted ion exchange method (20 min), the synthesis of AgCeY-1 adsorption effect of simulated oil research are the best, and has good reusability. The adsorption of TP and BT removal capacity order: AgCeY-1AgCeY-2AgCeY-3.
