Beschreibung
Zusammenfassung:	The invention discloses an ordered mesoporous Al-SBA-15 loaded sulfated zirconium oxide solid acid material. The material is obtained by taking an ordered mesoporous Al-SBA-15 material rich in surface Al-OH species obtained by grafting Al on the pore wall surface of the ordered mesoporous SBA-15 material as a carrier and immobilizing sulfated zirconium oxide. The solid acid material prepared by the invention has a highly regular and ordered mesoporous channel structure, larger specific surface area and pore volume, higher structural stability and adjustable mesopore wall surface acid amount, acid center type, acid density and acid strength, and the solid acid material shows excellent biodiesel yield, catalytic stability and reproducible reusability in catalyzing transesterification of biodiesel synthesized from soybean oil and methanol. 本发明公开了一种有序介孔Al-SBA-15负载硫酸化氧化锆固体酸材料，是以在有序介孔SBA-15材料孔壁表面嫁接Al后得到的富含表面Al-OH物种的有序介孔Al-SBA-15材料作为载体，固载硫酸化氧化锆得到。本发明制备的固体酸材料具有高度规整有序的介孔孔道结构、较大的比表面积和孔体积、较高的结构稳定性，且介孔孔壁表面酸量、酸中心类型、酸密度及酸强
