Rice straw was pretreated by ultra-high pressure (UHP)
ionic liquid micro emulsion (ILM)
and ILM in UHP environment (ILM+UHP) at mild temperatures. The effect of the pretreatments on the chemical composition
crystalline structure
surface morphology and enzymatic hydrolysis of rice straw were investigated. The results show that after the pretreatment with 1-ethyl-3-methylimidazolium acetate/cyclohexane/Triton X-100/n-butanol ILM at 500 MPa
