The catalytic reaction from synthesis gas to methanol in a fixed bed reactor with CNJ - 502 catalyst is studied. The effect of reaction temperature, pressure and space-velocity on the catalyst activity and space-time yield was also investigated. The result shows that CNJ -502 is a stable catalyst with wide temperature and high activity. This catalyst is suitable to be used for methanol synthesis process at low or medium pressure and in methanol-methanation procedure. As compared with ICI513 catalyst, CNJ -502 is superior to ICI5,13 in activity and thermal stability.
