N2 - The effect of Zn, Ni and activated carbon on the yield of lactic acid from cellulose was investigated to improve the lactic acid yield under alkaline hydrothermal conditions. The results showed that the lactic acid yield increased greatly in the presence of Zn, Ni and activated carbon. Central composite response surface method (RSM) design experimentation was used to find the optimal concentrations of Zn, Ni, activated carbon and NaOH, which indicated that 0.02. g Zn, 0.03. g Ni, 0.07. g activated carbon and 2.5. mol/L NaOH were the optimal concentrations. Under this condition, the highest lactic acid yield was 42%, which was much higher than previous results using only NaOH (15%). The confirmatory experiments on lactic acid yield proved that the proposed model of lactic acid yield can accurately predict the lactic acid yield from cellulose.
