Abstract

The invention relates to a porous particle floating activated carbon composite and a preparation method thereof.The composite is a new porous particle floating activated carbon composite which is prepared by conducting hot mixing and kneading on graphite powder, asphalt powder, pore-forming agent and thermosetting resin particles to prepare a char forming material, conducting secondary mixing and kneading on char forming material, glass beads and polyvinyl alcohol, and conducting compression moulding forming and drying and calcining, and a blank in the water pollution purification treatment field is filled in.The prepared floating carbon material has high carbon content, specific surface area and adsorption porosity and can be extruded into blocks or balls; according to the hollow spherical activated carbon, more importantly, the formed carbon material can float or suspend in water; due to the polymerizability of char forming components, the carbon material has higher strength and impact resistance compared with expanded graphite, has the proportion of 0.7-0.98 and has higher mechanical performance compared with expanded graphite.

Description

technical field [0001] The invention belongs to the technical field of industrial carbon composite material manufacturing and water pollution purification and treatment, and specifically relates to a porous granular floating activated carbon composite material and a preparation method thereof. Background technique [0002] Activated carbon is a porous carbon material with a well-developed pore structure and a large specific surface area. It has both physical adsorption and chemical adsorption. Often used as catalyst carrier or catalyst. However, in the process of using activated carbon on the market today, there are problems such as large specificity, small particles, and difficult regeneration. [0003] At present, oil pollution is mainly controlled by chemical and physical methods. However, the chemical method is easy to cause secondary pollution, and the environmentally friendly physical adsorption method is more and more popular. In order to remove oil pollution on th...
