Product distribution with different (a) reaction substrates, (b) PET dosages, (c) NaOH dosages, (d) temperatures, and (e) reaction times. Reaction conditions: (a) 40 mL CH3OH, 3 g PET bottles, 8 g NaOH, 0.93 g EG, 100 mg Ru/C, 160 °C, 1 MPa Ar, and 10 h; (b) 40 mL CH3OH, 8 g NaOH, 100 mg Ru/C, 160 °C, 1 MPa Ar, and 10 h; (c) 40 mL CH3OH, 3 g PET bottles, 100 mg Ru/C, 160 °C, 1 MPa Ar, and 10 h; (d) 40 mL CH3OH, 3 g PET bottles, 8 g NaOH, 100 mg Ru/C, 1 MPa Ar, and 10 h; and (e) 40 mL CH3OH, 3 g PET bottles, 8 g NaOH, 100 mg Ru/C, 160 °C, and 1 MPa Ar. Ar is used to exclude air from the autoclave and serves as an internal standard to facilitate the calculation of the amount of hydrogen produced during the reaction. The error bars represent the standard deviation of three independent experiments.
