Abstract

The invention discloses a process of using dogwood kernel to prepare activated carbon. The process includes: crushing dogwood kernels which are dried in the shade, using a 40-mesh sieve for screening, weighing and mixing dogwood kernels with zinc chloride with the concentration of 40-65wt% according to the liquid-solid mass ratio of 1.5-4.0:1, well mixing, ultrasonically impregnating for 2-12h, transferring to a crucible, activating in a muffle at 450-700 DEG C for 60-120min, cooling, using 1mol/L hydrochloric solution for boiling for 30min, repeatedly cleaning with 1mol/L hydrochloric solution, washing with hot water until the solution is neutral, drying an obtained activated carbon sample at 120 DEG C for 12h, grinding and using a 200-mesh sieve for screening to obtain the activated carbon. Using the dogwood kernels which are byproducts in production of dogwoods to prepare the activated carbon widens source ways for preparation of the activated carbon, and biomass resource recycling of the dogwoods is fully realized by manufacturing of high-quality activated carbon.

Description

The skunk bush fruit stone prepares activated carbon process
Technical field
The invention belongs to the activated carbon technology field, relate to the preparation of gac, be specifically related to a kind of skunk bush fruit stone and prepare activated carbon process.
Background technology
Skunk bush is Cornaceae Macrocarpium dungarunga or shrub, has another name called Fructus Corni, medicine jujube, fructus corni etc. after the fruit stoning after its maturation.Skunk bush is distributed in the north temperate zone, semi-tropical high mountain area.Main product is in countries such as China, Japan, Korea S, Britain, the U.S..In China, main product in Shaanxi, many provinces of 1O such as little, Gansu in Henan, Zhejiang, Shanxi, Shandong, Sichuan, peace.Wherein, the Qin in Shaanxi crust mountain area is one of main place of production of skunk bush, and YO has broken through 1,000,000 Kg.Present many to the research of skunk bush pulp, and the research that its fruit stone is utilized is less relatively, the dry fruit stone of skunk bush, its weight is about 1/3 of pulp, and a large amount of hard fruit stones have just been wasted valuable biomass resource as can not get effective utilization.
Activated carbon capillary is flourishing, high, the high adsorption capacity of specific surface area, is a kind of good sorbing material, is widely used in fields such as chemical industry, environmental protection, food and pharmacy, support of the catalyst and electrode materials.At present; Both at home and abroad mainly with coal, timber, municipal solid organic waste, rubber wood timber sawdust; Materials such as Exocarpium cocois (Cocos nucifera L), coffee berry shell, shell, rice husk are more as the research of raw material production gac, and its preparation method has high temperature carbonization, water vapour or stack gas activation method, chemical carbonization-activation method etc.Adopt different raw materials, different preparation, the performance of its gac has bigger difference.But with the skunk bush fruit stone is that relevant report is not seen in the research of feedstock production gac as yet.
Summary of the invention
The invention provides a kind of skunk bush fruit stone and prepare activated carbon process, may further comprise the steps:
The skunk bush fruit stone that will dry in the shade is pulverized, and crosses 40 mesh sieves, and taking by weighing skunk bush fruit stone and concentration according to liquid material mass ratio 1.5~4.0:1 is that the liquor zinci chloridi of 40~65wt% mixes; After fully stirring, under the UW condition, flood 2~12h, move in the crucible; Place 450~700 ℃ of activation 60~120min in the retort furnace, cooling, boil 30min with the hydrochloric acid soln of 1mol/L after; Continue to clean repeatedly with the hydrochloric acid soln of 1mol/L, the reusable heat water washing is to neutral, at last with gained activated carbon sample dry 12h under 120 ℃ of temperature; Pulverize 200 mesh sieves, promptly obtained cornel fruit nuclear activity charcoal product.
Preferred chlorination zinc concentration is 50wt%.
The liquid material mass ratio of preferred skunk bush fruit stone and liquor zinci chloridi is 3.0:1.
Preferred UW time of immersion is 4h.
600 ℃ of preferred activation temperatures, soak time 120min.
The by product that the skunk bush fruit stone is produced as skunk bush has not only been widened the source approach for preparing gac with its preparation gac, and the making of high-quality gac, has fully realized the biomass resource recycle of skunk bush.
