The invention relates to a papermaking pulping process, which belongs to the field of papermaking. A papermaking pulping process, the pulping process includes a second cooking step, the cooking liquid used for the first cooking, by mass percentage, consists of the following components: 5-8% sodium hydroxide, 0.5-1.0% sodium sulfite , sodium sulfide 1~2.5%, anthraquinone 0.3~0.5%, sodium dodecylsulfonate 0.02~0.1%, and the balance water; the cooking liquid used for the second cooking is obtained by diluting the cooking agent with water, and the water The dosage is 100 to 200 times that of the cooking agent, which is composed of graphene airgel powder and enzymes loaded thereon. The cooking agent of the invention is mainly used in the pulping process of grass raw materials. The cooking agent combines biological enzymes with carriers to ensure that the enzymes will not be lost during use, can be used repeatedly, and has a long service life.
