Abstract: 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.
