On the kinetics of liquid-phase methanol synthesis over commercial Cu/ZnO/Al2O3 catalyst

Enhancement of CO conversion in a novel slurry bubble column reactor for methanol synthesis

“…Setinc and Levec (1999) showed that most of the kinetic models of methanol synthesis have been developed for CO rich feed stocks, they satisfactorily matched their experimental data, while at very low CO 2 concentrations (or very low CO 2 /(CO 2 þ CO) ratio) these models failed completely. These models are also capable of predicting the decrease of the methanol production rate due to the water absorption on the catalyst surface as CO 2 concentration increases (Graaf et al, 1988;Setinc and Levec, 1999). Therefore a relatively low CO 2 /CO ratio is used in the three-phase synthesis and water production can be neglected ( Setinc and Levec, 1999).…”

Optimization of Methanol Yield from a Lurgi Reactor

“…However, the prevailing view is that methanol is produced primarily through CO 2 hydrogenation [17][18][19][20][21]. The kinetics of low-pressure methanol synthesis has been investigated by numerous authors [22][23][24][25][26][27][28][29].…”

Modeling and Simulation of an Integrated Micro Packed Bed Reactor-Heat Exchanger Configuration for Direct Dimethyl Ether Synthesis

“…To balance H 2 O formation and consumption via WGS (Eq 3), feed compositions with CO/CO 2 )1 have been preferred industrially [28]. Setinc and Levec review the most notable kinetic expressions derived for the methanol synthesis [29]. Some studies claim CO hydrogenation (Eq 1) to be the principle reaction in the process [30,31].…”
