Embodiment 1

[0030] 1) Use commercially available activated carbon fibers of the T1300 series, use butanol as a solvent, prepare arylphosphine or its derivatives and phosphoric acid or phosphate in proportion to the concentration of the activation solution, stir well, and impregnate the carbon fiber in the activation solution. In the solution, the activation solution should submerge the carbon fiber by about 1 cm. The temperature during the impregnation process is 45°C, and the impregnation time is 12 hours. Take it out, filter it, dry it in the sun, and then dry it in an oven at 95°C to a constant weight. Then it is placed in a muffle furnace, heated in a nitrogen environment, the heating temperature is 160 ° C, and the heating time is 60 minutes to obtain modified activated carbon fibers;

Abstract

The invention relates to a process method for treating octanol waste gas pollution and belongs to the technical field of treatment methods of organic pollutants in waste gases. The process method is characterized by comprising the following steps: by taking a compound of arylphosphine or a derivative thereof and phosphoric acid or phosphate as an activator, impregnating carbon fiber into an activation solution, performing heating activation in an inert gas, and performing cooling so as to obtain modified activated carbon fiber; putting the activated carbon fiber into an adsorber of an adsorption device; firstly feeding an octanol-containing gas into the adsorber, performing adsorption, and performing desorption on the adsorber which completes adsorption; and feeding organic mixed vapor generated from desorption into a condenser, performing condensation, performing liquid-liquid separation in a separator, collecting an upper liquid as organic matter octanol, collecting a lower liquid aswater, and overflowing and recycling octanol. The process method is high in desorption efficiency, the activated carbon fiber is long in service life, and the problem of low absorption and desorptionefficiency of octanol can be fundamentally solved.

Description

technical field [0001] The invention discloses a process method for treating octanol waste gas pollution, which belongs to the technical field of treatment methods for organic pollutants in waste gas. Background technique [0002] Octanol is a colorless transparent oily liquid with a pungent odor. The boiling point (standard atmospheric pressure) is 185°C and the vapor pressure (20°C) is 66.66 Pa. Octanol is an important chemical basic raw material and solvent, mainly used to make phthalates and aliphatic dibasic ester plasticizers such as dioctyl phthalate, dioctyl azelate and Dioctyl sebacate, diisooctyl phosphate, etc.; Solvent for adhesives, dehydrating agent for detergents; Defoamer for photographic papermaking, paint, printing and dyeing processes; Dispersant for oil slurry in ceramic industry; Mineral dressing agent, cleaning Agents, petroleum additives, etc. [0003] During the production, storage, and loading of octanol, as the liquid level of the product storage ...
