摘　　要：提出了有序多孔不锈钢的催化剂主动负载新工艺,并开发了相应的主动负载装备。通过SEM与超声振动技术等分析了主动负载工艺参数对有序多孔不锈钢负载性能的影响,并研究了采用主动负载工艺负载催化剂的有序多孔不锈钢的制氢性能。实验结果表明,通过驱动催化剂前体溶液在浸渍容器与储液容器之间往复流动可实现有序多孔不锈钢的催化剂主动负载。适宜的主动负载工艺参数为驱动压力0.002MPa、溶液流量0.3L/min。在该条件下,有序多孔不锈钢上催化剂负载均匀,且未堵塞多孔流道。在反应温度360℃、甲醇水混合溶液注射流量4 mL/h的条件下,相比采用传统工艺负载催化剂的有序多孔不锈钢,采用催化剂主动负载工艺负载催化剂的有序多孔不锈钢的甲醇转化率、H2流量与CO选择性分别提升了4.34%,4.23%,1.89%。A novel process of proactively loading catalyst onto ordered-porous stainless steel was proposed,and the corresponding proactively loading equipment were developed.The effects of proactively load process parameters on the loading performance of ordered-porous stainless steel were analyzed through SEM and ultrasonic vibration technology,and the hydrogen production performance of the ordered-porous stainless steel loaded by catalyst was studied.The experimental results indicate that the proactively loading of catalyst on the ordered-porous stainless steel catalysts can be achieved by driving the reciprocating flow of catalyst precursor solution between the impregnation container and the storage container.The suitable proactively load process parameters are the driving pressure of 0.002 MPa and the solution flow of 0.3 L/min.Under these conditions,the ordered-porous stainless steel has more uniform catalyst distribution and the catalyst does not block the porous flow channel.Compared with the traditional process for loading catalyst onto ordered-porous stainless steel,the proactively loading process can make the methanol conversion,H2 flow rate and CO selectivity increased by 4.34%,4.23%and 1.89%,respectively,when the reaction temperature is 360℃and the injection flow volume of methanol-water mixture is 4 mL/h.
