COMBINED TRANSFORMATIONS OF CARBON-DIOXIDE AND ETHANOL IN THE PRESENCE OF THE INTERMETALLIC COMPOUND TIFE0.95ZR0.03MO0.02, PD SIO2, AND AL2O3/

The influence of the composition of catalytic systems and the method f or H-2 feed into the reaction area on the degree of conversion of CO2 during its joint transformations with ethanol and on the selectivity o f formation of liquid organic products (ethyl acetate, acetaldehyde, a nd hydrocarbons) was studied at p = 15 atm and T = 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 comp osition with a palladium-containing catalyst, and the whole ternary ca talytic system. The selectivity of the reaction changed when the binar y catalytic composition consisting of the intermetallic and gamma-Al2O 3 was used. In this case, the fraction of C-9-C-14 alkanes 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 se lectivity to liquid products was 70-80% only when the hydrogen desorbe d from the intermetallic was used.
