style=\"color:red\">分子筛</span>是催化裂化(FCC)的速率控制组分。 FCC过程中,催化剂在反应器和再生器中往往面临高温水蒸气存在的苛刻环境。因此,<span style=\"color:red\">分子筛</span>的热稳定性和水热稳定性是催化剂最为关注的性能之一。由于FCC原料中通常含有V、Ni、Na、Fe等不同数量的金属污染物,会对催化剂造成污染及钝化。进料中存在的卟啉类有机复合物持续不断的沉积在催化剂表面,由于含钒的有机金属卟啉化合物在反应中转化形成V2O5, V2O5在水热条件下形成H3VO4组分,在高温水热气氛下加速<span style=\"color:red\">分子筛</span>骨架结构水解,破坏了<span style=\"color:red\">Y</span>型<span style=\"color:red\">分子筛</span>的晶体结构,从而降低了催化剂活性,影响产品选择性。稀土<span style=\"color:red\">Y</span>型<span style=\"color:red\">分子筛</span>在FCC中扮演重要的角色,稀土交换<span style=\"color:red\">分子筛</span>可以提高催化酸性、裂化活性和热与水热稳定性。此外, Na在高温水蒸气条件下也会对<span style=\"color:red\">分子筛</span>结构造成破坏。一方面,钠能够中和<span style=\"color:red\">Y</span>型<span style=\"color:red\">分子筛</span>B酸中心,降低催化裂化活性；另一方面,水热条件下钠的存在会加速破坏<span style=\"color:red\">Y</span>型<span style=\"color:red\">分子筛</span>的结构。有关<span style=\"color:red\">Y</span>型<span style=\"color:red\">分子筛</span>结构破坏的机理解释较多,然而该过程的动力学研究鲜有报道。反应动力学不能提供一个直接的反应机理,但是任何反应机理的提出必须符合反应动力学的数据。本文采用离子交换法分别制备了一系列不同Na含量USY,不同稀土含量USY,以及含钠和稀土的USY<span style=\"color:red\">分子筛</span>,通过固相动力学模型考察了上述<span style=\"color:red\">Y</span>型<span style=\"color:red\">分子筛</span>水热结构破坏活化能的变化及钒对其活化能的影响。结果表明, <span style=\"color:red\">Y</span>型<span style=\"color:red\">分子筛</span>的结构破坏存在三种路径,分别是脱铝、脱硅和La–O键的断裂。钒加速了<span style=\"color:red\">分子筛</span>骨架水解速率；钒钠具有协同作用,同时存在时对<span style=\"color:red\">分子筛</span>破坏作用更加显著； NaOH的形成是速率控制步骤；稀土稳定了<span style=\"color:red\">分子筛</span>的结构,降低了<span style=\"color:red\">分子筛</span>的水热脱铝速率；钒与定位于<span style=\"color:red\">分子筛</span>小笼里稀土作用,破坏<span style=\"color:red\">分子筛</span>的[RE–OH–RE]5+的RE–O键夺取<span style=\"color:red\">分子筛</span>的骨架氧,导致骨架结构崩塌。由于稀土本身稳定了<span style=\"color:red\">分子筛</span>的结构,同时钒稀土作用时形成稳定的REVO4固定了钒的流动性,因此钒对REY结构的影响是几种因素相互叠加和抵消的结果。","authors":[{"authorName":"杜晓辉","id":"be28fd86-eea2-4e91-b787-6ddcbc0a24b0","originalAuthorName":"杜晓辉"},{"authorName":"李雪礼","id":"c87539b3-824c-4ff8-815a-5a20c8a86883","originalAuthorName":"李雪礼"},{"authorName":"张海涛","id":"8c6551b6-bd99-49a7-94da-112b190ae8b7","originalAuthorName":"张海涛"},{"authorName":"高雄厚","id":"da7eda26-0338-4e34-b0aa-5b95ba264adf","originalAuthorName":"高雄厚"}],"doi":"10.1016/S1872-2067(15)60975-5","fpage":"316","id":"9fb48bd7-2c9d-403e-b0c2-c82417249e8f","issue":"2","journal":{"abbrevTitle":"CHXB","coverImgSrc":"journal/img/cover/CHXB.jpg","id":"18","issnPpub":"0253-9837","publisherId":"CHXB","title":"催化学报
