Abstract

The invention relates to preparation of vegetable active carbon, in particular to a method for manufacturing active carbon with bean vines. The manufacturing method mainly comprises the following steps that dried bean vines are cut into segments which are then dried and crashed; after dipped in phosphoric acid solution or peracetic acid solution, the material is placed in a carbonization furnace or a muffle furnace for carbonization and activation; then the material is washed with distilled water until the pH value is from 6.0 to 7.0; the active carbon of bean vines is obtained after drying. The manufacturing method is simple in technology, easy in material availability, high in carbon content rate and strong in adsorption effect. The invention makes the waste to the worth, overcomes the problems of environmental pollution and resource waste in traditional technology, with remarkable economic, environmental and social benefits.

Description

The preparation method of bean tendril absorbent charcoal
Technical field
The present invention relates to a kind of preparation of phyteral gac, specifically is with the climing preparation process of active carbon of beans.
Background technology
Along with the reach of science and the people pay attention to day by day to environmental issue, gac is applied to fields such as environmental protection, pharmacy, chemical industry more and more widely.Overwhelming majority carbonaceous material all can prepare gac, as timber, coal, shell, junked tire etc.But China's wood resources lacks, the preparation cost height; Shell distributes and disperses, not easily collecting; With waste or used plastics, tire is raw material, and preparation process pollutes environment easily.
The climing source of beans is abundant, and is cheap, how as waste.Selecting for use beans climing is the feedstock production gac, not only makes the climing changing waste into valuable of beans, and the comprehensive utilization new way is provided, and can also overcome environmental pollution and wasting of resources problem that traditional technology exists, has better economic, environment and social benefit.
Summary of the invention
At the problem that existing Preparation of Activated Carbon exists, the invention provides a kind of beans simple, environmental protection climing (climing, kidney bean is climing) method for preparation of active carbon as French beans.Present method not only provides new way for the climing comprehensive utilization of beans, makes it changing waste into valuable, and has solved the problem of environmental pollution that produces in traditional process for preparing active carbon.The gac of the climing preparation of beans, excellent property can be adsorbed each pollutant effectively.
The preparation method of bean tendril absorbent charcoal of the present invention comprises pulverizing, oven dry, charing, and preparation method's step is as follows:
(1) is cut into 1 centimetre of segment with beans are climing,, is ground into the bits end 100 ℃ of bakings 40 minutes down;
(2) pressed mass ratio 1: 1.3~1: 2.2, it is in 30%~50% the phosphoric acid 8~12 hours that bits ends be impregnated in concentration; Or, prepared peroxide acetate aqueous solution in 2: 3~3: 2 with distilled water with volume ratio again with A, B liquid volume ratio configuration in 10: 8 Peracetic Acid, will consider the end to be worth doing and soak fully wherein 6~8 hours;
(3) the bits end with above-mentioned immersion places charring furnace or retort furnace, and temperature rises to 330 ℃~420 ℃, carbonization-activation 60~100 minutes;
(4) stop heating after, in stove stewing 1.5~2 hours;
(5) with 90~100 ℃ of distilled water or deionized water with above-mentioned product wash to the pH value be 6.0~7.0, oven dry promptly makes bean tendril absorbent charcoal.
Major advantage of the present invention is as follows:
(1), utilize the discarded beans product gac of overgrowing, the raw material abundance, cheap, can realize its comprehensive utilization;
(2), the gac carbon content rate height of the climing preparation of beans, the hole prosperity, adsorption is strong, can remove noxious pollutant etc. effectively;
(3), preparation technology is simple, preparation speed is fast, easy handling production;
(4), climing with beans be raw material, economize on resources and help ecological environmental protection.
