Popis: The influence of the composition of catalytic systems and the method for H2 feed into the reaction area on the degree of conversion of CO2 during its joint transformations with ethanol and on the selectivity of formation of liquid organic products (ethyl acetate, acetaldehyde, and hydrocarbons) was studied atp=15 atm andT=573 K. A noticeable conversion of CO2 and ethanol into ethyl acetate and acetaldehyde was observed in the presence of only the intermetallic compound, its composition with a palladium-containing catalyst, and the whole ternary catalytic system. The selectivity of the reaction changed when the binary catalytic composition consisting of the intermetallic and γ-Al2O3 was used. In this case, the fraction of C9–C14 alkenes and alkenes with normal and iso structures was mostly formed; its content was as high as 40%. The degree of conversion of CO2 reached 30–36% and the selectivity to liquid products was 70–80% only when the hydrogen desorbed from the intermetallic was used.
