主 题：solid acid catalyst mesoporous silica sulfonic acid biodiesel esterification oleic acid
摘 要：Sulfonic acid functionalized mesoporous silica based solid acid catalysts with different morphology were designed and *** synthesized materials were characterized by various physicochemical and spectroscopic techniques like scanning electron microscopeenergy dispersive X-ray spectroscopy,Fourier transform infrared spectroscopy,Brunauer–Emmett–Teller surface area,thermogravimetric analysis and n-butylamine *** shape of catalysts particles plays an important role in its *** sulfonic acid functionalized mesoporous silica catalysts of spherical shape and the cube shape were assessed for catalytic activity in biodiesel *** catalytic biodiesel production reaction over the catalysts were studied by esterification of free fatty acid,oleic acid with *** effect of various reaction parameters such as catalyst concentration,acid/alcohol molar ratio,catalyst amount,reaction temperature and reaction time on catalytic activity were investigated to optimize the conditions for maximum *** was sulfonated cubic shape mesoporous silica which exhibited better activity as compared to the spherical shape silica ***,the catalyst was regenerated and reused up to three cycles without any significant loss in *** present catalysts exhibit superior performance in biodiesel production and it can be used for the several biodiesel feedstock’s that are rich in free fatty acids.
