Abstract
Recell®, a waste cellulose material, was used as a feedstock to synthesise ethylene glycol in a one-pot catalytic reaction. Two variables that were tested in this research were the optimal catalyst combination and reaction conditions. The optimal catalyst was found to be ammonium metatungstate hydrate in combination with 5 wt% Ru/C. Reaction with this catalyst yields 4,04% of ethylene glycol. Reaction optimisation was conducted by testing different reaction temperatures. Upon changing reaction temperature, the optimal reaction temperature was found to be 245°C which led to an improved ethylene glycol yield of 12,15%. This final ethylene glycol yield is still low compared to other raw lignocellulosic material. Low ethylene glycol yield was attributed more towards intrinsic factors within Recell® in lignin and inorganic impurities compared to reaction conditions. However, the effect other reaction conditions such as reaction time and hydrogen pressure is yet to be tested.
