Description

丙烯、异丁烯氨氧化流化床催化剂
本发明涉及由烯烃氨氧化制取不饱和腈的催化剂，其活性组份含有钼、铋、铁等多种金属氧化物。
Mo-Bi催化剂是用于烯烃制取不饱和腈(如由丙烯、异丁烯氨氧化制取丙烯腈或甲基丙烯腈)的反应中较成熟和较常用的催化剂，且自诞生以来不断有专利推出新的改进配方。如在活性组份中加入过渡金属以提高活性，增加产物的单收；加入稀土元素改善氧化还原能力；加入Na、P等元素以提高催化剂的耐磨性；加入Fe、Co、Ni等元素以抑制Mo的挥发，提高催化剂的稳定性等等。而近年来对丙烯腈催化剂的研究已较多地注重催化剂能够高效地利用氧或氨，即可以较低的氧比和氨比进行反应。显然，较低的氧比和氨比使得收率提高，然而低氨比具有更重要的意义是降低了反应尾气中未反应氨的含量，从而可相应减少用于中和未反应氨的酸的用量，这对降低生产成本和环境污染的控制都是极为有利的。专利CN96101529.2介绍了一种改进的Mo-Bi催化剂，其优点是催化剂具有较好的氧化还原稳定性、反应可以较低的氧比和氨比进料而仍有较好的反应收率。
本发明的目的是提供一种新的Mo-Bi催化剂，与上述对比文献介绍的同类催化剂相比，除仍具备其拥有的优点外，同时还有相对更高的丙烯转化率和较高的丙烯腈或甲基丙烯腈单程收率。
本发明提供的Mo-Bi催化剂含有Mo、Bi、Fe、Ni，以及任选地含有Mg、Co、Ca、Be、Cu、Zn、Pb、Sb、Mn、Cr、La、Ce、Sm、K、Rb、Na、Cs、B、W、P或V中的一种或多种金属氧化物，其含有的活性组份由下列通式表示：
Mo(12-g)BiaFebNicXdYeZfQgOx
其中：
X为Mg、Co、Ca、Be、Cu、Zn、Pb、Sb、Mn、Cr中的一种或两种以上的混合物，
Y为La、Ce、Sm中的一种或两种以上的混合物，
Z为K、Rb、Na、Cs中的一种或两种以上的混合物，
Q为B、W、P、V中的一种或两种以上的混合物，
a＝0.1～6，b、c、d、e、g＝0.1～10，f＝＞0～0.5，x为满足其它元素化合价所需的氧原子总数。
催化剂所用的载体为二氧化硅或氧化铝或两者的混合物，其含量为催化剂总量的(40～60)％(w.t.)。
然而，X最好为Mg或Co或其混合物；Y最好为La或Ce或其混合物；Z最好为Rb或Cs或其混合物；Q最好为W或V或其混合物。载体最好选用二氧化硅。
催化剂可用本领域技术人员熟悉的混浆法制备，或用通常熟知的其它方法进行制备，用于制备催化剂各组份的原料一般采用硝酸盐或其它可溶于水的盐类或酸类，以便各组份混合均匀。
与已有技术相比，本发明提供的催化剂具有较好的氧化还原能力，在范围更宽的反应条件下有很好的氧化还原稳定性，从而可以较低的空气/烯烃比以及较低的氨/烯烃而仍能得到较高的产物单收，在保持较高的烯烃转化率的前提下，丙烯腈或甲基丙烯腈的选择性有较显著的提高。另外，本发明提供的催化剂还相对具有更低的反应操作温度，这将有利于提高催化剂的使用寿命。
下面将通过实施例来进一步描述本发明的细节，通过实施例的评价数据可明显地看出本发明的积极效果。
在以下给出的实施例中，对催化剂考察评价的具体条件为：反应器      ：  流化床反应器，内径38mm催化剂填装量：  550克反应器顶压力：  0.085MPa  (表压)反应温度    ：  420/410℃反应时间    ：  4小时原料比(摩尔比)：丙烯/氨/空气＝1/1.15或1.05/9.5WWH         ：  0.06
反应产物用0 ℃酸液和水吸收，用气相色谱和化学分析结合分析产物。并计算碳平衡，当碳平衡在(95～105)％时为有效数据。
丙烯转化率、丙烯腈收率和选择性的定义为：
