Description
技术领域
本发明涉及到油品加氢技术领域，具体涉及一种裂解汽油加氢催化剂及其制备方法。
背景技术
随着成品油市场的饱和以及乙烯原料的市场紧缺，越来越多的炼油企业开始新建或扩建乙烯裂解装置，裂解汽油是乙烯裂解产物中的第一大副产品，主要有C5-C9化合物组成，总芳烃含量高达72%-78%，含有烯烃，二烯烃等易于结焦的化合物。裂解汽油通常采用二段加氢的方式脱除其中的杂质，一段加氢主要是脱除其中的烯烃等易于结焦的化合物，二段加氢主要用于脱除硫化物等含杂质的化合物。
CN201410193225.3公开了一种裂解汽油加氢精制的方法。该方法在活性组分分散较为均匀的镍系催化剂存在条件下将裂解汽油原料进行催化加氢反应，其中，镍系催化剂包括氧化铝-氧化钛复合物与ZSM-5构成的复合载体以及负载在所述复合载体上的氧化镍，且在所述镍系催化剂中，氧化镍的含量基于所述催化剂的重量为12%-20%；并通过控制反应过程中的反应条件来进行裂解汽油加氢精制从而获得双烯值和溴价都较低的下游精制原料。
CN201310585233.8公开了一种裂解汽油加氢催化剂及其制备方法。催化剂主要由氧化铝载体、活性组分钯、助催化金属组分钛、铈、镧、钇组成，助催化金属组分以可溶性金属盐为引入源，通过水热合成法涂覆在载体表面形成涂覆层，之后再在该涂覆层上负载活性组分钯，涂覆层的质量占载体质量的1%～20%，活性组分钯的含量为涂覆后载体总质量的0.15%～0.45%。
为了脱除裂解汽油中的烯烃类易结焦化合物，主要采用高镍或贵金属催化剂，但高镍催化剂存在易于聚集而失活，而贵金属催化剂价格昂贵。
发明内容
针对现有技术的不足，本发明从烯烃加氢反应机理入手，通过提高活性金属的分散度以及提高酸量等手段，制备了一种裂解汽油加氢催化剂，具有高的加氢饱和活性，而且价格低廉。
为了实现以上技术目的，本发明的技术方案如下：
本发明第一方面的技术目的是提供一种裂解汽油加氢催化剂，其以氧化铝为载体，其上负载分子筛和活性组分，所述活性组分为第VIB族金属和第VIII族金属，以催化剂的总重量计，分子筛占1-14%，优选2-10%，更优选3-7%；第VIB族金属为2-15%，优选3-8%，第VIII族金属为10-30%，优选15-25%；所述分子筛负载于催化剂外表面。

本发明第二方面的技术目的是提供上述裂解汽油加氢催化剂的制备方法，包括以下步骤：
（1）以含第VIB族金属的浸渍液浸渍氧化铝载体，经干燥和焙烧处理得到催化剂前驱体A；
（2）以含第VIII族金属盐和有机助剂的浸渍液浸渍催化剂前驱体A，然后干燥和焙烧得到催化剂前驱体B。
（3）将催化剂前驱体B与分子筛前驱体混合进行水热处理，然后经过干燥、焙烧和还原处理得到所述裂解汽油加氢催化剂。
进一步的，步骤（1）所述的第VIB族金属的浸渍液为第VIB族金属的磷酸盐或铵盐溶液，其配制方法为本领域技术人员熟知，采用等体积浸渍或过饱和浸渍的方式。所述的第VIB族金属优选Mo和/或W。
进一步的，步骤（1）的干燥条件为：干燥温度90-200℃，干燥时间3-6小时。焙烧条件为：焙烧温度300-500℃，焙烧时间3-6小时。
进一步的，步骤（2）的含第VIII族金属的浸渍液为第VIII族金属的硝酸盐、醋酸盐或硫酸盐溶液等，可以采用等体积浸渍的方式，所述的第VIII族金属为Ni和/或Co。
进一步的，步骤（2）所述的有机助剂为：含有羟基和/或羧基的醇类或有机酸，其中碳原子数为3-10。具体的，选自乙二醇、丙三醇、丁二醇、戊二醇、醋酸、柠檬酸、丙二酸、丁二酸和戊二酸中的至少一种。
进一步的，步骤（2）的干燥条件为：干燥温度90-200℃，干燥时间3-6小时。焙烧条件为：焙烧温度300-500℃，焙烧时间3-6小时。
进一步的，步骤（3）所述的分子筛前驱体为硅源和/或铝源、沉淀剂、模板剂和水混合后形成的凝胶，其配制方法为本领域技术人员熟知，采用沉淀或溶胶凝胶的方式。所述的硅源一般是硅酸钠、正硅酸乙酯、硅溶胶和层析硅胶中的一种或几种；所述铝源一般是偏铝酸钠、氢氧化铝和拟薄水铝石中的一种或几种；所述沉淀剂选自氢氧化钠、氨水和氢氧化钾中的至少一种；所述模板剂选自十六烷基三甲基溴化铵、乙二胺、正丁胺、四丙基溴化铵、乙醇、四乙基氢氧化铵、四乙基溴化铵、三乙胺、二正丙胺、二异丙胺和甲基纤维素中的一种或几种。

本发明第三方面的技术目的是提供所述裂解汽油加氢催化剂的应用，其用于裂解汽油的烯烃加氢处理过程。
与现有技术相比，本发明的催化剂具有如下优势：
（1）本发明的裂解汽油加氢催化剂中加入分子筛，并使分子筛负载于催化剂外表面而不是与载体混捏，一方面有利于提高分子筛与活性金属接触面，同时有利于分子筛负载到活性金属的活性位上，充分发挥分子筛提供H质子的能力，提高催化剂的加氢活性；另一方面增加了分子筛的利用率，因此降低了分子筛的用量，降低催化剂的成本。
（2）本发明通过先将第VIB族金属负载到载体上，然后负载第VIII族金属，再负载分子筛，然后还原处理得到裂解汽油烯烃加氢催化剂；其中第VIB族金属负载到载体上可以修饰载体表面的高活性位，减弱载体与第VIII族金属的相互作用，提高第VIII族金属的分散度，同时第VIB族金属与第VIII族金属有相互作用，可以阻碍第VIII族金属的聚集。
本发明的其它特征和优点将在随后的具体实施方式部分予以详细说明。
