Coal honeycomb activated carbon with high iodine value

Abstract

The invention discloses high iodine value coal honeycomb activated carbon, which comprises the preparation of honeycomb activated carbon, and the preparation method comprises the following steps: S1,selecting high-quality coal-based carbon, carbonizing, activating, and crushing into coal high iodine value activated carbon powder of 200 meshes or more, S2, selecting high-quality high-adsorption non-metal ore powder and other binders as raw materials and auxiliary materials, mixing and stirring the coal high iodine value activated carbon powder and water fully into slime; S3, mixing, extrudingand filtering large-particle impurities to form coal slime with high plasticity through several series-connected pug mills and filters, S4, ageing the coal slime for sufficient time to enable moisturein the coal slime to be uniformly distributed, S5, extruding and forming a honeycomb wet blank through a forming machine after ageing the coal slime, and cutting the blank, and fully dehumidifying and drying in a drying room to obtain the high iodine value coal honeycomb activated carbon. The iodine value, the forming rate and the honeycomb-shaped strength of the coal honeycomb-shaped activated carbon can be greatly improved, the loss of raw materials is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of active carbon, in particular to a coal honeycomb active carbon with high iodine value. Background technique [0002] Honeycomb activated carbon is suitable for the treatment of organic waste gas (triphenyl, toxic and harmful gas) in factories with large air volume and low concentration. It is suitable for indoor air purification and treatment of flue gas from restaurants, air conditioners, refrigerators, copiers, etc. And as a catalyst carrier, used for adsorption and recovery of benzene, toluene, xylene, acetone, oil and natural gas, CS2 and other organic solvents, petrochemical industry production, natural gas purification, desulfurization, deodorization and wastewater treatment, biochemistry, paint industry, underground places , Air purification and deodorization in tanneries, animal breeding places, high iodine value honeycomb activated carbon compared with low iodine value honeycomb activated carbon, the adsor...

Problems solved by technology

And as a catalyst carrier, used for adsorption and recovery of benzene, toluene, xylene, acetone, oil and natural gas, CS2 and other organic solvents, petrochemical industry production, natural gas purification, desulfurization, deodorization and wastewater treatment, biochemistry, paint industry, underground places , Air purification and deodorization in tanneries, animal breeding places, high iodine value honeycomb activated carbon compared with low iodine value honeycomb activated carbon, the adsorption capacity is stronger, the applicable environment is wider and more high-end, the cost performance per unit volume is higher, no need to short The time is replaced repeatedly to prolong the service life of environmental protection equipment. The existing high iodine value honeycomb activated carbon preparation technology has the disadvantages of complex production process, many process steps, and difficult to master the ratio of raw materials. It can no longer meet the high iodine value (especially the new standard 700 iodine value and the new standard 800 iodine value) coal-based honeycomb activated carbon production, there will be honeycomb shape in the production process, high humidity mud, low hardness, iodine value does not meet the standard, low labor efficiency and other problems
