The finite element method is applied to analysis and optimize the design of the hydrogenation reactor skirt support area,and stress of the risk section is assessed and strength is checked.The fill rate of in- sulation materials in insulation zone,skirt thickness and the cylinder wall thickness have been optimally de- signed.The results show that there is an optimization between fill rate of insulation materials in insulation zone and temperature gradient in skirt support area,and cylinder wall thickness of skirt has a great impact on the maximum equivalent stress in the hydrogenation reactor skirt support area.
