Abstract
The invention discloses rice hull modified active carbon adsorption desulfurizing agent, which is prepared from the following raw materials in parts by weight: 30-40 parts of rice hull, 100-120 parts of bamboo charcoal, 8-10 parts of quartz powder, 10-13 parts of acrylic acid, 8-10 parts of acrylamide, 2-3 parts of ammonium persulfate, 10-15 parts of natural clay, 20-30 parts of cassava straw, 15-20 parts of siderite, 4-5 parts of modified diatomite and a right amount of water. According to the invention, the active carbon produced by using rice hull and cassava straw as raw materials has well-developed pore structure, large specific area and excellent adsorption effect; macromolecular compounds, such as acrylic acid, are used for adhesion, so that the active carbon is not easy to disintegrate, can reduce powder falling rate and is easy to recycle; with the siderite, sulfur can be removed effectively. The adsorption agent disclosed by the invention is suitable for purification of air and water, is low-cost, has wide application range, and is suitable for industrial production.
