Abstract

The reversed flow operation of a bench scale catalytic reator was applied to the synthesis of methanol from CO-CO 2 -H 2 mixtures at 50 bar, over a ICI copper-based commercial catalyst. Temperature and concentration profiles develop and wander back and forth through the reator, depending upon the direction of the flow. The relaxation characteristics of the different region pathways on the catalytic surface are also responsible for the significant transients generated in the gas-phase composition. The experimental results lead to considerable insight into the mechanism of methanol synthesis. The influence of the cycle length, flow rate, and inlet temperature on the ractor performance are also reported
