Abstract
一种多孔氧化铝负载钴费托合成催化剂由四氧化三钴、金属助剂氧化物和氧化铝组成,其重量组成为四氧化三钴:金属助剂氧化物:氧化铝=(25‑50):(1‑10):100。本发明具有高活性和稳定性的用于浆态床和固定床费托合成反应的优点。
Description
技术领域
本发明涉及一种费托合成催化剂及制备方法及其应用,具体地说是一种多孔氧化铝负载钴基费托合成催化剂及制备方法及其应用。
背景技术
我国煤炭主体能源格局长期保持,大力发展以煤为原料的合成油(CTL)技术,实现煤炭洁净、优化深度利用,生产超净液体发动机燃料和高级润滑油等,能够缓解世界能源需求和结构状况的矛盾。
费托合成液体燃料无氮、无硫、芳烃含量低,作为一种清洁燃料颇受市场青睐。目前世界各国成功开发了合成油技术,南非Sasol公司的固定流化床(SAS)和浆态床(SSPD)工艺,此外还有Shell公司的固定床SMDS工艺,Syntrolem公司的GTL工艺,Exxon公司的AGC-21艺以及Energe International公司的GasCat工艺等。
费托合成用的钴基催化剂常采用将钴盐和金属助剂盐直接浸渍在惰性氧化物载体上制得。例如,壳牌公司采用氧化硅为载体,其导热性能较差,在工业装置应用中催化性能不能充分的发挥。埃克森公司采用氧化钛为载体,但氧化钛载体的钴负载量低于15%,且催化剂低温焙烧性强度低,高温焙烧能够提高催化剂强度,但会导致金属载体强相互作用,影响催化剂性能。氧化铝一种是工业上常用催化剂载体,它具有独特的孔道结构、内比表面及强的吸附能力,在制备费托合成催化剂方面也得到广泛研究,但是存在着孔道结构不丰富、钴负载量受限的问题。由于氧化铝载体孔道少,导致催化剂的钴含量较低,反应活性不能得到提升,最终影响产能和工业应用。
发明内容
为解决上述问题,本发明的目的在于提供一种具有高活性和稳定性的用于浆态床和固定床费托合成反应的一种多孔氧化铝负载钴费托合成催化剂及制备方法和应用。
本发明引入多孔碳源作为氧化铝载体骨架,焙烧后得到多孔氧化铝载体,为金属钴提供丰富的落位点,极大地提高了费托合成催化活性。
本发明催化剂由四氧化三钴、金属助剂氧化物和氧化铝组成,其重量组成为四氧化三钴:金属助剂氧化物:氧化铝=(25-50):(1-10):100。
如上所述金属助剂氧化物为氧化铁、氧化镍、氧化铜、氧化锌。
本发明催化剂具体制备方法如下:按照氧化铝前驱体占多孔碳源的20-100wt%,称取多孔碳源作为骨架,按最终催化剂组成,称取氧化铝前驱体配制成固含量为10-30wt%的氧化铝前驱体水溶浆,在超声波震荡下,全部浸渍于多孔碳源上,然后于60-90℃下真空干燥12-36h后得到含骨架的氧化铝前体,再于450-800℃下焙烧4-12h后得到氧化铝载体;称取可溶性钴盐和可溶性助剂金属盐等体积浸渍于上述氧化铝载体,于60-90℃下干燥12-24h,300-400℃下焙烧2-6h,得到最终催化剂。
如上所述,多孔碳源为多壁碳纳米管(8-15nm)、富勒烯(C60或C70)、介孔碳(立方结构)、中孔活性炭(木炭、椰壳、果核、稻壳或纤维素)或碳分子筛等的一种。
如上所述,氧化铝前驱体为碳酸铝氨、氢氧化铝或拟薄水铝石。
如上所述,可溶性钴盐为硝酸钴或醋酸钴。
如上所述,可溶性助剂金属盐为硝酸铁、硝酸铜、硝酸镍或硝酸锌。
如上所述的费托合成钴基催化剂,可以在固定床反应器中进行还原、反应;还原条件为:350-450℃,0.3-1.5MPa,GHSV=500-1000h-1,恒温12-36h,采用氮中氢还原气,H2含量为15%-85%(v/v);反应条件为:170-230℃,2.0-3.0Mpa,GHSV=700-2500h-1,H2/CO(v/v)=2.0-2.5。
如上所述的费托合成钴基催化剂,可以在浆态床反应器中进行还原、反应;还原条件为:270-320℃,0.2-1.2MPa,GHSV=500-800h-1,恒温12-36h,采用氮中氢还原气,H2含量为15%-85%(v/v),转速为400-800rpm;反应条件为:170-230℃,2.0-3.0MPa,GHSV=700-2500h-1,H2/CO(v/v)=2.0-3.0,转速为400-800rpm。
本发明催化剂具有孔道结构丰富、传质传热性能好的特点,用于费托合成反应表现出优异的催化性能。
具体实施方式
实施例1
