A simple synthesis route for the formation of Cu-Zn-Al-oxide with high surface area and porosity has been presented, tuned, and evaluated for CS2 removal from CO2 stream. Saturation of aqueous suspension of raw Cu, Zn, Al oxides with a stream of CO2 at mild conditions and subsequent thermal treatment was used for preparation of a series of materials with the same (Cu + Zn/Al) molar ratio but differentiated carbonate content. They were characterized by techniques: X-ray diffraction (XRD), differential thermal gravimetry with evolved gas analysis (DTG/EGA), N2 sorption, scanning electron microscopy and energy dispersive spectroscopy SEM-EDS and were subjected to tests for CS2 sorption from the CO2 stream at 90 °C. It was shown that Cu-Zn-Al sorbents can effectively remove CS2 if the specific surface area exceeds 40 m2/g and the mean CuO and ZnO crystallites size is not greater than 15 nm. Obtaining active sorbents of sulphur compounds by CO2 saturation of raw Cu, Zn, Al oxides can be an effective route for preparation of active traps for CS2 removal from CO2 at low temperature.
