Catalyst Recycling Experiments
(A) Recycling experiments of the phosphidated Ni/SiO2 catalyst produced by liquid-phase phosphidation with TOP. Reaction conditions: phosphidated Ni/SiO2 (100 mg), guaiacol (5 mmol), n-octane (9.5 mL), 568 K, 5 MPa H2, 1 hr reaction duration. The initial three runs were performed 3 times.
(B) Carbon content of the fresh phosphidated Ni/SiO2 catalyst and catalyst after 1, 3 and 6 recycling runs, respectively.
