- 14Another likely interpretation is that CO2 produced by LWGS may severely inhibit the reduction of LA with H2. However, this possibility is excluded as the hydrogenation rate of LA does not slow down when 1 MPa CO2 was deliberately added into H2.
- 15The presence of carboxylic acids may significantly depress the LWGS reaction under otherwise identical conditions. This possibility is confirmed by the fact that the rate of H2 formation via LWGS decreased from 0.58 to 0.32 mmol gAu−1 s−1 when 4.53 mmol butyric acid was deliberately added.
- 19The majority of the byproducts was n-propanol, which was generated by the excessive hydrogenation of lactic acid.
