Carbon acid gas synthesis in carbon mono-oxide oxidation reaction is considered. Differential equations system for modelling the process is offered and results of solution of reduced system with diffusion neglected and constant reaction coefficients are presented. Temperature was taken equal $T=520^{\circ }C$, partial pressures of incoming components were $P_{CO}=2.13\cdot 10^{-3}$ and $P_{O_{2}}=2.66\cdot 10^{-2}$ for carbon mono-oxide and oxygen respectively. Peculiarity of the presented model is an attempt to take into consideration surface close interactions through surface close concentrations of $CO$ and $O_2$.
