In situ hydrogenation of phenolic compounds over Ni-based catalysts: upgrading of lignin depolymerization products

A series of Ni-based catalysts, including Ni/SiO 2 –ZrO 2 , Ni/HZSM-5, Ni/Al 2 O 3 , Ni/SiO 2 , Ni/AC and Ni/CMK-3, were prepared to produce H 2 from the aqueous phase reforming (APR) of methanol.
