Asphalt resin composite spherical activated carbon with developed apertures and low energy consumption and preparation method thereof

Abstract

The invention discloses asphalt resin composite spherical activated carbon with developed apertures and low energy consumption. The asphalt resin composite spherical activated carbon with the developed apertures and the low energy consumption is characterized by being prepared from the following raw materials including, by weight, 46-50 parts of octadecyl acrylic ester, 39-44 parts of ethylhexanoate, 2-3 parts of benzoyl peroxide, 1-2 parts of N,N'-methylene bisacrylamide, 18-20 parts of butanediol, 10-13 parts of ethyl acetate, 1-2 parts of sodium dodecyl benzene sulfonate, appropriate amount of distilled water, appropriate amount of acetone, 25-28 parts of sulfonated gilsonite powder, 3-4 parts of attapulgite, 2-3 parts of nano-silicon dioxide, 0.8-1 part of a silane coupling agent kh560, 5-6 parts of hydrochloric acid with concentration of 15% and 5-6 parts of a sodium hydroxide solution with concentration of 12%. Through the addition of modified nano-titanium dioxide and the attapulgite, the amount of apertures and the sizes of the apertures of products are increased, reaction time and reaction energy consumption are greatly reduced through process innovation, the industrial production is easy to achieve, the hardness is large, and the recycling can be achieved.

Description

technical field [0001] The invention relates to the field of materials, in particular to pitch resin composite spherical activated carbon with developed pore size and low energy consumption 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 developm...
