A kinetic model for the deactivation of copper/zinc oxide catalyst during the methanol synthesis has been developed. This model is of the Langmuir-Hinshelwood-Hougen-Watson type and considers two types of active sites for the deactivation of catalyst. One of the site types on copper is allocated for
## Abstract **BACKGROUND:** Ethylene carbonate (EC) was synthesised via urea and ethylene glycol (EG) over zinc/iron oxide catalyst. By so doing, the byβproduct, EG, generated in the process of producing dimethyl carbonate by the transesterification route was converted back to the raw material, EC.
The kinetics of low-pressure methanol synthesis from CO, CO, and H, on a commercial Cu/ZnO catalyst was investigated in a Berty-type reactor at low overall conversion to reduce the influence of chemical equilibria (reaction conditions: p = 3-5 MPa, T = 483-543 K). At constant Hz partial pressure the
