To improve utilization rate of the raw material and economic benefit during the process of lignocellulose pretreatment, the microwave-acidification steam explosion pretreatment was proposed and the experiment research on it was performed. The percentage of sugar in the hydrolysate, the cellulose content in the residual solid and the change of microstructure after the microwave-acidification steam explosion pretreatment and the acidification steam explosion pretreatment for lignocelluloses was compared, taki...
