摘要： Abstract: The present invention provides a method for producing high-activity lignin and by-product furfural and an application. The method comprises: using a dissolving pulp pre-hydrolysate and/or sulfite cooking liquor as the raw material, and catalyzing by employing an acid as a catalyst to obtain the lignin and furfural, wherein the acid is one or a combination of at least two of sulfuric acid, phosphoric acid, nitric acid, hydrochloric acid, and acetic acid. According to the method, the yield of the obtained lignin and furfural is further increased by catalyzing the dissolving pulp pre-hydrolysate and/or the sulfite cooking liquor with the acid. Lignin especially has higher reactivity and low molecular weight, and the ratio of 5-methyl furfural in furfural to furfural is in a proper range, so that the strength of furan resin prepared from furfural can be further improved.
