Abstract
The nature of mineralizing agent (HF, NH4F) and the Si/F ratio in the synthesis conditions is found to affect the formation of Zr- and Cu-containing acid sites on the surface of zirconium-containing hierarchical zeolites (Cu/Zr-MTW) modified by copper (2 wt.%). It is shown that in the conversion of 50 and 80 vol.% ethanol the highest yield of 1,3-butadiene is achieved in the presence of Cu/Zr-MTW (NH4F, Si/F = 4) catalyst, which is characterized by higher total surface acidity according to TPD-NH3.
