Abstract ZSM-22 zeolite samples were synthesized with and without the use of trimethoxyphenylsilane in conjunction with nanometric silica beads, producing materials with intracrystalline micro-mesopore structures. Subsequently, the solids were desilicated by varying the NaOH solution concentration. The XRD results indicated that the samples were highly crystalline and the nitrogen adsorption analysis showed that the desilication of the materials with the presence of organosilane caused a greater increase of surface area, external area, mesoporous volume, and higher yields of solid.

分级孔结构ZSM-22沸石的制备

摘要 ZSM-22 沸石样品在使用和不使用三甲氧基苯基硅烷与纳米二氧化硅珠的情况下合成，产生具有晶内微介孔结构的材料。随后，通过改变NaOH溶液浓度使固体脱硅。XRD 结果表明样品是高度结晶的，氮吸附分析表明，在有机硅烷的存在下材料的脱硅导致表面积、外面积、介孔体积的更大增加，以及更高的固体产率。
