| titleOfInvention | Method for using waste cotton stems to prepare catalyst carriers for desulfurization |
| abstract | The invention discloses a method for using waste cotton stems to prepare catalyst carriers for desulphurization. The method includes drying, cutting, crushing and carbonizing the waste cotton stems, then grinding the waste cotton stems into powdered carbon with the particle size ranging from 200 meshes to 300 meshes, and uniformly mixing tar with 50-70% bitumen content with a 0.5-2% organic flow agent to prepare forming adhesive; then uniformly mixing from 60 to 70% of the powdered carbon of the cotton stem, from 25 to 35% of the forming adhesive and from 3 to 5% of water, placing the mixture into a screw extruder and realizing extrusion forming under the extrusion pressure ranging from 8.0MPa to 10.0MPa and with the compression ratio ranging from 1.5 to 1.6; and sequentially carbonizing, activating and oxidizing formed colloidal particles, then washing the colloidal particles until the colloidal particles are neutral, and drying the neutral colloidal particles. Intermittent forming production is changed into continuous forming production owing to the extrusion forming of the screw extruder, accordingly, production efficiency is improved, and yield can be increased; and the organic flow agent is added, the proper extrusion pressure and the proper compression ratio are matched, flowability of materials further can be improved, extrusion forming is facilitated, and the catalyst carrier with excellent strength and adsorptivity are obtained. |
