The invention relates to the technical field of straw resource utilization, in particular to a method for pretreating straw through combination of ionic liquid and steam explosion. According to the method, straw is pretreated by adopting an ionic liquid and steam explosion combined method, [Bmim] [PF6] is adopted as the ionic liquid, straw powder is impregnated through the ionic liquid, the ionic liquid can permeate into a cellulose, hemicellulose and lignin cross-linked space structure in the impregnation process, and then the cellulose, hemicellulose and lignin cross-linked space structure is formed in a steam explosion mode; under the condition of instantaneous pressure loss, on one hand, a three-element cross-linked space structure can be destroyed, and on the other hand, the ionic liquid soaked in the straw can degrade hemicellulose, so that the three-element cross-linked space structure is destroyed more thoroughly, and the efficiency of the pretreated straw powder during subsequent treatment is improved. The method is simple in process, effective separation of the three elements in the straw can be achieved, and the method plays a positive role in subsequent high-valued conversion of the straw.

This invention provides a reactive deodorizing agent matrix, its preparation method, and its application, specifically relating to the field of deodorizing agent technology. The reactive deodorizing agent matrix provided by this invention, by mass percentage, comprises the following raw materials: 37-65% organic wax, 12-20% emulsifier, 1-5% butene copolymer, 1-3% antioxidant, 1-5% oxidant, and 20-30% zinc-containing compound. This invention utilizes the oxidant to induce the zinc-containing compound to react with the wax, emulsifier, butene copolymer, and antioxidant under specific conditions, forming a chelate centered on zinc ions. This chelate contains various functional groups that can interact with odor molecules to form chemical bonds, resulting in an irreversible chemical reaction under quasi-chelation, rapidly and permanently removing odor molecules. The antioxidant stabilizes the chemical bonds between the zinc ion chelate and the odor molecules, improving the long-term stability of the chemical bonds and maintaining the long-term stability of the deodorizing effect.
