Green environment-friendly light-weight porous reinforced compound spherical active carbon and preparation method of active carbon

Abstract

The invention discloses green environment-friendly light-weight porous reinforced compound spherical active carbon, which is characterized by being prepared from the following ingredients in parts by weight: 40 to 43 parts of propyl methacrylate, 41 to 44 parts of vinyl stearate, 25 to 28 parts of ethyl alcohol, 2 to 3 parts of tert-Butyl peroxybenzoate, 1.5 to 2.5 parts of ethylene glycol dimethacrylate, 1 to 2 parts of polyethylene glycol monolaurate, a proper amount of distilled water, a proper amount of acetone, 25 to 28 parts of sulfonated asphalt powder, 3 to 4 parts of waste paper scrap, a proper number of hydrochloric acid solutions with the concentration being 1 percent, a proper number of strong sodium oxide solutions with the concentration being 1 percent, 5 to 6 parts of cotton pulp, 0.8 to 1 part of methyltrimethoxysilane and 2 to 3 parts of urea. The compound spherical active carbon has the advantages that during the asphalt enveloped liquid preparation, the ingredients such as the waste paper scrap and the cotton pulp are added; through modification, the highly porous structure is formed; the density is low, and the porosity is high; meanwhile, the cost is low; the prepared product can be effectively subjected to oil and water separation; the ash content is small; poisonless and harmless effects are achieved; the spherical active carbon can be repeatedly utilized.

Description

technical field [0001] The invention relates to the field of materials, in particular to a green, environment-friendly, lightweight, porous and reinforced composite spherical activated carbon and a preparation method thereof. Background technique [0002] Spherical activated carbon has been widely used in related fields such as medicine, environmental protection and catalyst carrier because of its good sphericity, high packing density, less particle shedding and fast adsorption and desorption speed. Spherical activated carbon is mainly divided into three categories according to different raw materials: coal-based spherical activated carbon, polymer resin-based spherical activated carbon and pitch-based spherical activated carbon. Among them, coal-based spherical activated carbon has the advantages of cheap raw materials and wide sources, but coal-based activated carbon has high ash content, many impurities, and low mechanical strength, which limits its application and develo...
