Reaction kinetics for the synthesis of methanol from CO and H2 on a copper catalyst

Abstract: The kinetics for the low-pressure synthesis of methanol from CO and H, were studied in a small integral reactor. The mole fraction of CO was varied from 0.1 to 0.54, the total pressure from 3 to 9 MPa and the temperature from 483 to 545 K. Using the maximum likelihood approach, seventeen possible reaction rate correlations were evaluated statistically. Among these models three appear to fit the experimental data satisfactorily.

“…The reactor capacity appears to increase with an increase of the total pressure, the temperature or the solids flow. Such an influence of the pressure and temperature results from the reaction kinetics (Kuczynski et al, 1986a), whereas the solids flow determines the methanol partial pressure in the reactor influencing in this way the reaction rate, as discussed in our previous paper (Westerterp and Kuczynski, 1987). For high solids flow rates, the reaction rate approaches the initial reaction rate because the methanol partial pressure is kept low and the reverse reaction does not take place.…”

“…On the other hand, care was taken to avoid too long contact times in the first reactor in order to operate the reactor below the equilibrium composition. This is necessary to maintain a high selectivity and to avoid catalyst degradation (Kuczynski et al, 1987b). The experimental CO conversion in the first reactor varied between 0.25 and 0.58.…”
