摘要：

Ordered mesoporous Mg-Al composite oxide-supported K catalysts (xK/OMMA) were prepared and used for soybean oil transesterification with methanol. The prepared xK/OMMA demonstrated a much higher soybean oil conversion (up to 97.0%) along with a 99.8% selectivity to fatty acid methyl ester and a desirable reusability, compared with K-based catalysts prepared with the same K loading and using ordered mesoporous alumina or mesoporous Mg-Al mixed oxide as support. The superior catalytic performance of xK/OMMA is associated with the excellent structural and surface properties of support OMMA, thus benefiting the generation of catalytically active sites and their highly homogenous dispersion.
