Description
本发明属于催化剂及其制备和应用于领域，具体地说涉及一种用于合成气生产α-烯烃的结构化铁基催化剂及制备方法和应用。
长链α-烯烃是指不饱和键位于链烃端位的碳四以上、碳十六以下的单烯烃或混合烯烃。由于分子中含有活性位(烯键)，α-烯烃容易接入各种官能团，衍化成醇、酸、酯等化合物，广泛应用于表面活性剂、增塑剂等精细化学品生产。目前α-烯烃主要作为共聚单体用于生产聚乙烯，占总消费量的44.1％。用于共聚单体的最为广泛的品种是C4(1-丁烯)、C6(1-己烯)和C8(1-辛烯)，在生产高密度聚乙烯和线性低密度聚乙烯(HDPE/LLDPE)中使用于这些共聚单体可改善PE密度，提高其抗撕裂和拉伸强度。其次，α-烯烃也用于生产高碳醇，最终产品为增塑剂和洗涤剂，占总消费量的19.6％。高碳醇是表面活性剂和增塑剂的基础原料，世界每年消费量已达千万吨左右。辛醇主要用于制备各种酯类，每年在全世界销售额约十多亿美元。庚醇可用于制备香料和香精，价值很高；再有，α-烯烃还用于生产聚α-烯烃(PAO)，占总消费量的16.6％，PAO是高端润滑油基础油的原料，其黏度指数高，价格是矿物油的2-3倍。此外，α-烯烃也作为乳化剂、皮革处理剂、润滑油添加剂、防锈剂、织物整理剂、纸张用于化学品等产品的原料。
国外α-烯烃总生产能力约为212万吨，国内生产能力26万吨。并且，国内缺乏生产长链α-烯烃的能力，1-辛烯和1-己烯几乎完全依赖进口。
传统的α-烯烃生产工艺有石蜡裂解法或乙烯齐聚法。石蜡裂解法一般采用于脱油精制蜡为原料。原料蜡预热后与蒸汽混合，于约550℃下在管式裂解炉中进行反应。对于乙烯齐聚法生产α-烯烃，乙烯齐聚反应是在三乙基铝催化剂作用于下，乙烯发生受控链增长反应，聚合成一定链长的烯烃。具体又可分成两步法、一步法及SHOP工艺等。
传统的α-烯烃生产工艺基于蜡或乙烯，原料来源于石油。伴随着世界范围内油气资源的萎缩，国内外正在进行着能源原材料的多样化变革。煤、生物质或天然气通过合成气间接转化为清洁液体燃料和化学品的非石油路线日益受到重视。

所述的载体二氧化硅含量：1～40％、第一助剂含量选1～2％；第二助剂金属氧化物含量选2～6％，余量为活性组分为铁。
一种结构化铁基催化剂的制备方法，步骤如下：
1)用热分散法制备单分散颗粒催化剂前驱体A：
将去结晶水的硝酸铁和第一助剂的硝酸盐以及无定形二氧化硅按其重量比要求加入到正辛醇中混合，各物质总重量占混合液的3～20％，搅拌，硝酸盐溶解，升温到140～180℃度后，恒温4h，冷却后抽滤烘干，得到黑色固体，经行星磨研磨20～40分钟后置于马弗炉中400-600℃焙烧5h，得到催化剂前驱体A；
2)将第二助剂按重量比溶于水或乙醇，用配制好的第二助剂的溶液干法浸渍上述催化剂前驱体A，老化12～24小时，然后于100～130℃干燥，于300～1200℃焙烧4～10小时，压片，筛分，制得结构化铁基催化剂。
所述的结构化铁基催化剂的各成分重量百分比为：载体二氧化硅含量：1～40％、第一助剂含量选1～2％；第二助剂金属氧化物含量选2～6％，余量为活性组分为铁。

所述的催化剂前驱体A的粒度为50～60nm，且为球形，呈单分散分布。
一种结构化铁基催化剂的应用，用于合成气生产α-烯烃在固定床进行费托合成反应的作条件为：还原条件为：300～500℃，0.2～1.2MPa，400～1500h-1(V/V)，6～18h，纯氢气氛；合成气反应条件为：190～360℃，0.5～5.0MPa，400～20000h-1(V/V)，H2/CO＝1/1～3/1。
第二种结构化铁基催化剂的应用，用于合成气生产α-烯烃在浆态床中进行费托合成反应的作条件为：还原条件为：300～500℃，0.2～1.2MPa，400～1400rpm，400～1500h-1(V/V)，6～18h，纯氢气氛；合成气反应条件为：190～360℃，0.5～5.0MPa，400～20000h-1(V/V)，400～1400rpm，H2/CO＝1/1～3/1。
本发明与已有技术相比具有如下优点：
1.本发明的催化剂使用了热分解法制备催化剂主活性组分，与传统方法相比，本发明所得粉体具有形貌规整，孔径均匀等特点，使最终制备的催化材料拥有了独特的形貌和微观结构。由图1可见，本发明的所述方法可得到颗粒均匀，且呈球形，粒度约70nm，单分散结构的铁物相。该结构使铁催化活性中心更为一致，有利于活性中心的构建。同时，形貌均匀的粉体更易形成理想的孔道结构。这些独特的结构使本发明催化剂具有较高的α-烯烃选择性。
2.本发明的催化剂由于铁与助剂之间作用强度合理调配，具有很高的还原程度和炭化程度。通过载体类型的选择和用量的调整、助剂的使用，使催化剂活性组分与载体之间的作用强弱合理，即防止了铁组分的烧结，也避免了难还原成份的出现，使催化剂具有优良的化学性能。结构和化学两方面因素的协同效应下，使催化剂具有较高的长链α-烯烃选择性和活性。
3.催化剂可以从粉末压片成型，也可通过喷雾干燥成型，具有良好的机械性能。
本发明提供了一种生产α-烯烃的新的工艺路线，它以合成气为原料，在本发明的催化剂的作用下，直接合成α-烯烃。与现有技术相比，本发明在原料、目标产品、技术路线、催化剂制造方法等方面均不相同，从而形成一个与已有技术截然不同，具有突出创新性的生产α-烯烃的新技术。本发明的单分散的结构和适宜的金属-载体化学作用，使催化剂产生适合α-烯烃生成的活性中心，因而具有优良的选择性。
