Please cite as: CHEMIK 2015, 69, 9, 572–577 Carbon monoxide conversion process described with equation (1) is one of the most widespread processes in the chemical technology This is an exothermal reaction with clearly temperature-dependent equilibrium constant (K1057 = 1). For achieving high degree of conversion, low temperature is beneficial, but then reaction rate is low. Due to thermodynamic limitation, CO conversion...

Introduction Carbon steel (CS), thanks to the good mechanical properties and low production costs is wide use in different fields of industry [1–2]. Unfortunately, CS undergoes corrosion in aggressive solutions [3]. The use of inhibitors is one of the most widely practical methods for protection of metals against corrosion. Corrosion inhibitors are compounds which...
