Zn–La–Zr–Si oxide composition has been investigated in the ethanol-to-butadiene process using ethanol–water mixtures with different water content. An increase of H2O content in the initial reaction mixture decreases ethanol conversion, 1,3-butadiene selectivity, yield and productivity. The results of in situ FTIR spectroscopy (with ethanol and acetone as probe molecules) have shown the main reason for a decrease in activity of the catalyst to be H2O adsorption on active sites of aldol…
