英文摘要	Instead of conventional aluminum isopropoxide and silica sources, commercially available solid aluminosilicate gel with SiO2/Al2O3 = 25 was selected to synthesize UZM-8 zeolite with diethyl-dimethylammonium hydroxide (DEDMAOH) as the structure-directing agent (SDA) in the Na+-free system. The structure-directing function and decomposition of DEDMAOH were analyzed. With the irregular stacking of MWW layers, UZM-8 zeolite with solid aluminosilicate gel as silica and aluminum sources possessed better stability during crystallization, better crystallinity, higher surface area, clearly separated Si-29 MAS NMR resonances, and more acid sites accessed by pyridine and 2,4,6-trimethyl-pyridine than conventional synthesized UZM-8 zeolite, which resulted in obvious improvement in ethylene conversion with little loss in ethylbenzene selectivity at higher temperatures.
