“…The other possible mechanisms for direct DCO x include the production of formic acid as an intermediate and ketonization ,–. It has also been proposed that DCO 2 occurs through the formation of formic acid, which readily decomposes into CO 2 and H 2 ,,. The H 2 that is produced would then be consumed for hydrogenation of the resulting C=C bond.…”

Selective Deoxygenation of Biomass‐Derived Bio‐oils within Hydrogen‐Modest Environments: A Review and New Insights

2016

Research development of processes for refining bio‐oils is becoming increasingly popular. One issue that these processes possess is their high requirement for H2 gas. In response, researchers must develop catalysts that perform deoxygenation while minimizing H2 consumption—selective deoxygenation. Unlike traditional deoxygenation processes, selective deoxygenation reactions and catalysts represent an information gap that, prior to this publication, has yet to be reviewed. This review addresses the gap by providing both a summary of recent research developments and insight into future developments of new catalytic materials. Bifunctional catalysts containing a combination of oxophilicity and an active metal phase appear to be the most beneficial for selective deoxygenation processes in a H2‐modest environment. It is important that catalysts have a supply of disassociated hydrogen, because without such, activity and stability will suffer. The authors recommend to maximize the use of internally available hydrogen in bio‐fuel, which may be the only viable approach for deoxygenation if external H2 gas is limited. This would be possible through the development of catalysts that promote both the water–gas‐shift and deoxygenation reactions.

“…RESULTS AND DISCUSSION It was shown in [1,7,14] that the high yields of hydrocarbons in the deoxygenation of fatty acids in the presence of palladium catalysts are reached when the reaction is run in the atmosphere of hydrogen. The transformation of SA into hydrocarbons predomi nantly occurs according to the scheme [7] R…”

The activity and selectivity of palladium, copper, platinum, and nickel catalysts in the decarbon ylation of stearic acid into hydrocarbons were studied at a 14 atm hydrogen pressure and temperatures of 300-350°C. If γ alumina was used as a carrier, the catalysts formed the series Pd > Cu > Pt > Ni according to desired product yields. Quantum chemical simulation was performed to show that the free energy of acti vation increased in the same series. The same metals deposited on mixed tungsten and zirconium oxides cat alyzed decarbonylation with a low yield of C 17 hydrocarbons, likely because such a superacidic carrier could catalyse cracking of olefins or their oligomers formed.
