摘要：采用浆液法制备用于甲烷水蒸气重整制氢(MSR)的Ni/γ-Al2O3/FeCrAl网状催化剂,利用扫描电子显微镜、X射线衍射、氮气物理吸附、热震法和超声振荡法研究该催化剂的表面形貌、晶型结构、孔特性、热稳定性和涂层与基体间的结合性能。采用自行搭建的MSR试验系统,以甲烷转化率为指标对自制网状催化剂和商用颗粒型催化剂在不同反应温度和空速下的催化性能进行评价。结果表明:与商用颗粒型催化剂相比,自制网状催化剂具有更大的比表面积,在高空速下的甲烷转化率明显更优;但自制网状催化剂应用于MSR反应还存在产物中CO含量较高、催化剂易积炭等问题,有待进一步优化催化剂的活性组分。
Ni/γ-Al2O3/FeCrAl mesh-type catalyst for methane steam reforming(MSR)was prepared by slurry method.The surface morphology,crystal structure,pore characteristics,thermal stability and adhesion between coating and substrate of the catalyst were studied by scanning electron microscope,X-ray diffraction,nitrogen physical adsorption,thermal shock,and ultrasonic vibration test techniques.The MSR test system was set up to evaluate the performance of the self-made mesh-type catalyst and commercial pellet catalyst at different temperatures and space velocities.The results showed that the mesh-type catalyst had a higher specific surface area and better conversion rate of CH4 at high gas hourly space velocity than that of the commercial catalyst.However,there are still some problems for the mesh-type catalyst,such as high CO content in the product of SMR and carbon deposition on the catalyst,which need to be further optimized.
