Extended batch reactions, in which poplar is treated at 340°C in the presence of Raney nickel, water and hydrogen, give oil in yields of 36‐41% with oxygen contents of 12‐17%. Methane and carbon dioxide formation, hydrogen utilisation and cracking of the oil are favoured by fresh Raney nickel. There is some competition for methane and carbon dioxide production, higher hydrogen pressures favouring the former in the presence of fresh catalyst. Efficient mass transfer increases hydrogen utilisation and lowers the oil viscosity. It is concluded that Raney nickel has no significant advantage over other more convenient forms of nickel.
