PROCESS FOR PRETREATING A LIGNOCELLULOSIC MATERIAL |
摘要 |
<p>A process for pretreating a lignocellulosic material having a lignin content in the range from equal to or more than 10 wt% to equal to or less than 50 wt%, based on the total weight of the lignocellulosic material, which process comprises: mixing the lignocellulosic material and an alkaline aqueous solution, which alkaline aqueous solution has a pH of equal to or more than 9.0, in a solid to liquid weight ratio of equal to or more than 25:75 to equal to or less than 60:40, in a mixer to produce an aqueous slurry; and heat-treating the aqueous slurry at a temperature in the range from equal to or more than 50°C to equal to or less than 200°C to produce a heat-treated aqueous slurry comprising a pretreated lignocellulosic material.</p> |
