In order to explore the influence of tangential intake structure on the heat transfer characteristics of the catalyst bed in a radial flow methanol synthesis reactor,the opening angle θ of the inner and outer distribution cylinders of the radial flow methanol synthesis reactor was changed,and the ordinary intake method at the inlet of the mixed gas was changed to tangential intake.The tangential intake radial flow methanol synthesis reactor structure with θ = 0°,15°,30°,and 45° was established,and the temperature field in the reactor under each angle was simulated and calculated using CFD software.The study shows that the tangential intake structure with a reasonable tangential angle can improve the mixing degree of the fluid in the reactor,increase the contact area of the reactants,enhance heat transfer,not only improve the uniformity of the reactor temperature distribution but also improve the reaction efficiency and product yield.Moreover,when θ = 30°,the temperature field distribution in the reactor is the most uniform.
