Catalytic synthesis of methanol

This review deals with methanol synthesis from carbon oxides and hydrogen, the macroscopic and detailed mechanisms of the process, the nature of activ e sites, intermediate surface species, and process kinetics. The data on is otopic labeling, temperature programmed desorption (TPD) with sample treatm ent with various substances, various kinetic data, including non-steady-sta te kinetics for intermediate species, spectral, and other data obtained by the authors and other researchers, are presented. Methanol synthesis and wa ter-gas shift reaction are shown to be coupled processes. The detailed mech anism of methanol synthesis was developed at a level that is sufficient for constructing theoretical (mechanism-based) kinetic model. This model descr ibes the kinetics of methanol synthesis and water-gas shift reaction over b road ranges of conditions, as well as the anomalous kinetics of methanol sy nthesis over deactivated catalysts.
