Studies on VPO/TiO2 Catalysts for Selective Oxidation of n-Butane to Maleic Anhydride [PDF]

open access: yes, 2014
低碳烷烃(C1-C4)的选择氧化是当今催化研究领域面临的巨大挑战之一。而在其中,正丁烷选择氧化制顺酐是迄今唯一一个实现了工业化生产的反应。目前,工业上该反应的有效催化剂仍为非负载VPO催化剂。与非负载催化剂相比,负载型催化剂具有诸多优点:(1)活性相较大的比表面积;(2)较高的机械强度;(3)较好的导热性能。很多学者对负载型VPO催化剂进行了研究,但其催化性能仍远低于非负载催化剂,有关催化剂的作用机制也有待深入研究。本论文制备了一系列负载VPO催化剂 ...
