Kinetic modelling for the hydrogenolysis of bio-glycerol in the presence of a highly selective Cu–Ni–Al ₂ O ₃ catalyst in a slurry reactor

A kinetic study on the liquid phase hydrogenolysis of glycerol was carried out in a slurry reactor in the presence of a highly selective Cu–Ni–Al ₂ O ₃ catalyst at different reaction temperatures (180–220 °C) and pressures (3–6 MPa), and very high selectivity was achieved (∼95%) towards 1,2-propanediol (1,2-PDO).
