Abstract

A kind ofly produce process of active carbon with the citric acid fermented with dry sweet potato waste residue.Be about to the citric acid fermented with dry sweet potato waste residue after chemical activating agent (as zinc chloride) is handled, carry out that charing, activation, acid are boiled, make after the rinsing, drying, pulverizing.The present invention utilizes the waste behind the citric acid fermented with dry sweet potato to produce gac, for having opened up a kind of new raw material in the manufacturing field of gac, reduced the manufacturing cost of gac, and fundamentally solved of the pollution problem of citric acid fermented with dry sweet potato waste residue to environment, make a silk purse out of a sow's ear, have remarkable economic efficiency and social benefit.

Description

Method with producing active carbon from waste slag of citric acid fermented with dry sweet potato
The present invention relates to a kind of manufacture method of gac.
At present, according to the purposes difference, can use wood, bamboo, shell, beastly bone, mud coal, brown coal etc. respectively as the raw material of making gac.Usually, wood chip, charcoal as main raw material, gac per ton need consume about 4 cubic metres in timber, and along with timber resources is in short supply day by day, make the manufacturing cost of gac constantly increase, in addition, China produces waste residue 10～12.5 ten thousand ton every year approximately with the producer of citric acid fermented with dry sweet potato, the ideal treatment process is not arranged at present as yet, cause environmental pollution.
The object of the present invention is to provide a kind ofly to replace wood chip, charcoal to produce gac, thereby reduce the manufacturing cost of gac, and the waste residue that solves citric acid fermented with dry sweet potato is handled problems with the citric acid fermented with dry sweet potato waste residue.
Task of the present invention is finished by following scheme: be about to the citric acid fermented with dry sweet potato waste residue after chemical activating agent (as zinc chloride) is handled, carry out that charing, activation, acid are boiled, make after the rinsing, drying, pulverizing.Specifically, with the citric acid fermented with dry sweet potato waste residue with 1: 1～1.5(weight) ratio be 1.8 gram per centimeters at proportion 3Liquor zinci chloridi in flood 10～15 hours after, in temperature is charing 60～90 minutes in 300～400 ℃ the charring furnace, then in being 650～750 ℃ activation furnace, temperature activates 90～105 minutes, in 10% hydrogen chloride solution, boiled 3.5～4.5 hours then, rinsing is to PH5～7, dry in 100～150 ℃ loft drier, pulverize the back by 100 mesh sieves.
The present invention utilizes the waste behind the citric acid fermented with dry sweet potato to produce gac, for having opened up a kind of new raw material in the manufacturing field of gac, reduced the manufacturing cost of gac, and fundamentally solved of the pollution problem of citric acid fermented with dry sweet potato waste residue to environment, make a silk purse out of a sow's ear, have remarkable economic efficiency and social benefit.
The active carbon finished products that makes by the inventive method meets the Ly216-79 of Ministry of Forestry primary standard through chemical examination, can use for industries such as food, medicine, chemical industry, and reach the standard-required of outlet gac.
Below by embodiment the present invention is described in more detail.
Embodiment 1:
(proportion is 1.8 gram per centimeters at 1200 grams with 800 gram citric acid fermented with dry sweet potato waste residues 3) dipping 12 hours in the liquor zinci chloridi, in temperature is charing 90 minutes in 320～350 ℃ the charring furnace, in temperature is activation 97 minutes in 650～670 ℃ the activation furnace, in 10% HCl solution, boiled 4 hours then, be washed to PH5～7, in 110～120 ℃ loft drier, dry, pulverize the back, obtain 169 gram powdered active carbons by 100 mesh sieves.
Embodiment 2:
(proportion is 1.8 gram per centimeters at 800 grams with 800 gram citric acid fermented with dry sweet potato waste residues 3) dipping 12 hours in the liquor zinci chloridi, charing is 60 minutes in 350～380 ℃ charring furnace, in temperature is activation 102 minutes in 650～670 ℃ the activation furnace, in 10% HCl solution, boiled 4 hours then, be washed to PH5～7, in 130～140 ℃ loft drier, dry, pulverize the back, obtain 90 gram powdered active carbon goods by 100 mesh sieves.
