Synopsis
乙烯作为重要的化工原料，其产量是衡量一个国家化学工业发展水平的标志之一。早期理论与实验研究表明，相对于乙烷的热脱氢制取乙烯，以O2为氧化剂的乙烷氧化脱氢(ODE)更为有效。 在众多的乙烷氧化脱氢催化剂体系中，稀土基催化剂的反应温度亟待降低，负载型LiCl体系的稳定性有待进一步提高。围绕上述问题，研究制备了典型纳米稀土氧化物，进而对比研究其与相应大尺寸稀土氧化物的ODE催化性能，探究不同载体上负载型LiCl催化体系ODE催化性能与其酸碱性间的关系。实验结果表明：（I）溶液沉淀法和均匀沉淀法均能制得纳米氧化镱，其催化乙烷氧化脱氢的活性稍好于大尺寸的商品氧化镱，650℃时的乙烯收率为38%；（II）LiCl的负载，可显著增强催化剂的碱性，以固体酸、HZSM-5和MgO为载体的负载型LiCl催化剂均具有较好的初活，碱性较强的催化剂具有更佳的ODE催化性能，600℃时的乙烯收率最高可达80%；LiCl的引入能促使固体酸载体中的氧化锆发生四方相向单斜相的转变、氧化钛发生锐钛矿相到金红石相的转变，该相变均始于样品中心；（III）随反应中LiCl的持续流失，以碳酸锂形式存在的Li的量随之增加，催化活性逐渐降低。
