Liquefaction of crop residues for polyol production

The liquefaction of crop residues in the presence of ethylene glycol, ethylene carbonate, or polyethylene glycol using sulfuric acid as a catalyst was studied. For all experiments, the liquefaction was conducted at 160C and atmospheric pressure. The mass ratio of feedstock to liquefaction solvents...
