| titleOfInvention | A method for comprehensive utilization of plant straw |
| abstract | The invention discloses a comprehensive utilization method of plant straws, which belongs to the field of straw treatment. The method of the present invention comprises the following steps: (1) crushing plant stalks, adding water according to the solid-liquid mass ratio of 1: (6-10), heating at 110-140°C for 1-3h, hot water extraction for solid-liquid separation, and collecting the first stage Liquid, the solid is the first-stage solid after washing with water, collect the washing liquid and merge with the first-stage liquid, add flocculant, filter and separate, collect the solid phase components to obtain secondary components; (2) make the acid-catalyzed hydrolysis of the first-stage solid Extract xylose from the hemicellulose, separate the solid and liquid to obtain the second-stage solid and the second-stage liquid; (3) add NaOH solution to the second-stage solid, heat, extract, wash with water until neutral, filter, and dry to obtain cellulose; (4) Add HCl to the liquid in the second stage, cool down and filter to extract the precipitate, wash with water until neutral, and dry to obtain lignin. The method of the invention has zero discharge to the outside, clean production in the whole process, and fundamentally prevents pollution. |
