| description | The invention discloses a paper pulp-capacitance carbon joint production method, and belongs to the technical field of paper pulp and carbon materials. The method comprises the following steps: (1) pulping papermaking raw materials by using an alkaline method, carrying out filter pressing separation, and cleaning paper pulp; (2) concentrating, drying and grinding a black liquor to obtain alkali lignin dry powder; (3) mixing the alkali lignin dry powder with an alkali activator and a co-activator, grinding, and aging; (4) performing high-temperature carbonization-activation on the mixture; (5) performing post-treatment on the carbonized material to obtain capacitor carbon; and (6) recovering alkali from the water washing liquid of the carbonized material, and circularly using the alkali liquid for pulping and the alkali activator of the capacitor carbon. The byproduct alkali lignin generated by alkaline pulping is directly used as the raw material for manufacturing the capacitor carbon, the alkali is recovered |
