Acetone hydrogenation in a fixed bed reactor packed with spherical catalyst particles was simulated to study the effects of inlet gas velocity and particle diameter on hydrogenation reaction.Computational results show that the catalyst particles in the reactor are almost isothermal,and the high isopropanol concentration appears at the lee of the particles.With the increase of inlet velocity,the outlet isopropanol mole fraction decreases,and the total pressure drop increases drastically.Small diameter catalyst particles are favorable for acetone hydrogenation,but result in large pressure drop.

Acetone hydrogenation in a fixed bed reactor packed with spherical catalyst particles was simulated to study the effects of inlet gas velocity and particle diameter on hydrogenation reaction .Computational results show that the catalyst particles in the reactor are almost isothermal, and the high isopropanol concentration appears at the lee of the particles. When the increase of inlet velocity, the outlet isopropanol mole fraction decreases, and the total pressure drop increases drastically. Small diameter catalyst particles are favorable for acetone hydrogenation, but result in large pressure drop.
