The investigation of ethylene oxide (EtO) catalytic incineration over Pt/Al2O3 catalyst conducted in fixed bed reactor (diameter of 315 mm) showed that significant degree of EtO adsorption occurred when the inlet gas temperature was lower than ignition temperature (180 degrees C). This observation was a basis for the development of a hybrid reactor for EtO removal using modified spouted bed with draft tube loaded with Pt/Al2O3 catalyst. The annular region of the bed was divided in two sections, the "hot" (reaction) section contained about 7% of catalyst and it behaved as a catalytic incinerator, while the "cold" (sorption) section, with the rest of the catalyst, behaved as an sorber. The catalyst particles recirculated between two sections by using a draft tube riser. To formulate the process parameters dynamics of EtO sorption on Pt/Al2O3 catalyst and Al2O3, support were studied. The proposed system for EtO removal gives the same efficiency as the fixed bed catalytic converter. The experimental data show that process is attractive for low EtO concentrations, because it enables significant energy savings. At steady state conditions temperature in the sorption section of 80-100 degrees C was maintained. In the reaction section initial heating to the temperature of 200 degrees C is sufficient to start up selfsustained deep EtO oxidation.
