The catalytic properties of ZnLaZrSi-oxide systems prepared on the basis of different types of silica (SBA-15, MCM-41, MCM-48, MCF, large-pore silica, Aerosil A-175) in the process of obtaining 1,3-butadiene (BD) from ethanol–aqueous mixtures were studied. It has been determined that the porous structure characteristics are not critical parameters for achieving high selectivity and yield of BD. The activity and selectivity of catalysts depends on the acid–base properties of their surface, which are determined by the type of silica. High values of selectivity for BD are achieved in the presence of catalysts based on KSKG silica (SBD = 65-68%) and SBA-15 (SBD = 63%).

ZnLaZrSi-Oxide 体系在乙醇-水相混合物制备 1,3-丁二烯过程中的催化性能

基于不同类型二氧化硅（SBA-15、MCM-41、MCM-48、MCF、大孔二氧化硅、Aerosil A-175）制备的ZnLaZrSi-氧化物体系在获得1,3过程中的催化性能研究了乙醇-水性混合物中的丁二烯 (BD)。已经确定多孔结构特征不是实现高选择性和 BD 产率的关键参数。催化剂的活性和选择性取决于其表面的酸碱性质，这由二氧化硅的类型决定。在基于 KSKG 二氧化硅 (SBD = 65-68%) 和 SBA-15 (SBD = 63%) 的催化剂存在下，BD 的选择性值很高。
