Description
技术领域
本发明涉及纳米材料催化剂制备技术领域;更具体地,涉及一种金属硫化物油性分散体的制备方法及其应用。
背景技术
目前在世界范围内原油资源正在逐步趋于重质化,预计2020年以后,重质原油储量约占全球原油可采储量的50%左右,增产的石油将主要是重劣质原油。与此同时,随着环保法规的日益严格和产品质量标准的不断升级,要求必须对重油资源进行深度加工,以提高资源利用率,进而改善油品质量。因此,重质油尤其是渣油的高效加工利用已成为当今炼油工业面临的重大挑战和机遇。
渣油加氢工艺是一种实现渣油高效绿色转化的有效途径,按照反应器类型的不同,渣油加氢工艺分为固定床、移动床、沸腾床和浆态床4大类。其中,浆态床渣油加氢工艺具有原料适应性强、渣油转化率高、轻油收率高、工艺简单、操作灵活以及反应器结构简单等优点,具有良好的发展前景。除了催化加氢,延迟焦化也是一种重要的渣油高效转化加工技术,其由于具有原料适应性强、装置投资和操作费用低,加工渣油经济性好等优势而被广为应用,主要用于提高液体(轻质油)收率和生产石油焦。渣油中含硫化合物几乎都集中在稠和芳环上,其容易发生进一步缩合而变成更大的分子进入石油焦;在延迟焦化过程中,H2S产量仅占原料总硫量的20-30%,脱硫率较低,原料中硫进一步富集在石油焦中,C-S键相对更容易断裂。为此,研究者基于上述研究和渣油热解机理,提出了一种基于原位氢结合催化剂的添加剂技术,其原理是通过在反应原料中引入供氢剂,以提供活性氢(原位氢),并结合催化剂催化作用,针对含硫自由基进行饱和,避免其进一步结焦,尽可能使其保持在较小的分子状态,在焦化过程中易馏出,实现将硫尽可能地转移至液体或气体组分中,从而降低石油焦中的硫含量。此技术不需要对装置进行改造,投资少,市场应用价值大。然而,目前研究的渣油加氢或延迟焦化催化剂多为含相关活性组分的微米级多相催化剂或水溶性催化剂,其在油中分散性差,催化效果有待进一步提高。为此,开发具有良好油溶性的拟均相纳米催化材料,可望为此技术的发展提供一种新思路。
水热法和溶剂热法是无机材料合成中常用的方法,这两种方法反应条件温和,所得产物结晶度高,晶型好,但是产物易团聚,分散性不好。专利CN102992405A采用溶剂热法以钼酸钠、硫化钠为原料在水-乙醇混合溶剂中制备纳米核壳结构,部分核壳结构生长不完整且粘连严重。为了控制水热或溶剂热过程中产物的团聚,通常向其中添加一些表面活性物质。CN105731542A公开了一种反相微乳液体系中制备二硫化钼微球的方法,该方法在微乳液体系中经过高温水热还原、硫化得到微米级二硫化钼。但该发明制备的二硫化钼尺寸较大,在溶液中很难分散,作为催化剂使用时其有限的表面原子比限制了催化性能,此外,该制备方法比较复杂。CN02117835.6公开了一种重油悬浮床加氢裂化新工艺,虽然该工艺所用的催化剂使用了以铁-镍-锰-钼-钴等多金属水溶性盐类复配而成的催化剂,却并未提及这些水溶性前驱物分解所生成的硫化物是水溶性或油溶性的。孙志礼(东北大学,2008)等人用化学沉淀法制备的纳米二硫化钼粉体,虽然粒径达到了纳米级,也比较均匀,但存在团聚现象,制得的粉体不够分散。还有研究人员通过N-甲基吡咯烷酮的辅助研磨或者超声降解,实现了二硫化钼在水中的稳定分散。但该二硫化钼在油相溶液中难以分散,且制备过程难以规模化制备,产品质量不稳定。
发明内容
本发明要解决的第一个技术问题是提供一种金属硫化物油性分散体的制备方法。该方法制得的金属硫化物可稳定分散到油相中,金属硫化物的颗粒粒径为10-40nm,放置六个月不发生团聚现象;使用该催化剂进行重质油加氢反应,加氢转化率≥85%,脱硫率≥85%。
本发明要解决的第二个技术问题是提供一种金属硫化物油性分散体在重质油加氢和延迟焦化上的应用。
为解决上述第一个技术问题,本发明采用如下技术方案:
一种金属硫化物油性分散体的制备方法,包括以下步骤:
S1、将金属源和硫源分别溶于溶剂中,得到金属源溶液和硫源溶液;
S2、将金属源溶液和硫源溶液通入内循环超重力反应器中混合,然后调整混合溶液pH值,继续反应得到金属硫化物前驱体溶液;
S3、向前驱体溶液中加入还原剂和表面活性剂,调节反应液pH,然后转移至高压反应釜,在一定温度下反应一段时间后得到金属硫化物混合液;
S4、过滤并洗涤产物,除去杂质,将金属硫化物分散于有机溶液中,得到金属硫化物分散体。
