Optimization studies of oil palm empty fruit bunch liquefaction for carbon cryogel production as catalyst in levulinic acid esterification

Liquefaction of oil palm empty fruit bunch (EFB) using 1-butyl-3-methylimidazolium chloride was investigated in this study. The experiments were designed based on central composite by response surface methodology (RSM). The optimum conditions for the predicted liquefied EFB yield of 80.97 wt% was ob...
