The chemical equilibrium compositions and equilibrium constants of methanol synthesis reaction
starting from carbon monoxide
carbon dioxide and hydrogen
were studied experimentally at p=4. 0-6. 6MPa and t=220-260℃. Meanwhile
based on the experimental data of Kp measured in this paper
the thermodynamic prediction of Kp from Kf and equation of state was studied and it was found that the chemical equilibrium of methanol synthesis can be described well by using Cherednichenkos Kf Ⅰ and Bissetts Kf
