Abstract
The present invention relates to a kind of method that utilization bagasse prepares activated carbon, crushed after bagasse is dried, be then added in sodium carbonate liquor and soak 10 20h, the weight ratio of the bagasse and sodium carbonate liquor after drying is 1:3‑6；By the bagasse dehydration after immersion, it is subsequently placed in Muffle furnace and carries out charing process, obtain carbide；By carbide chlorohydric acid pickling, then neutrality is washed to, finally dries and sieve, produce.The recycling that this method solve bagasse, the waste for avoiding resource and environmental pollution provide effective way, sugar industry can be directly used for by its activated carbon prepared, added value of product is high, good social and economic benefit can be produced, and the activated carbon decolorizing ability of the present invention is strong, stability is good, and intensity is high, safety non-toxic.
Description
Technical field
The present invention relates to a kind of preparation method of activated carbon, the method that especially a kind of utilization bagasse prepares activated carbon,
Belong to technical field of fine.
Background technology
China is the big country of Sugar Production and consumption, and cane sugar manufacture is with a long history in China.Bagasse is sugar industry
Principal by product, the composition of bagasse is based on cellulose, hemicellulose and lignin, albumen, starch and soluble sugar content
It is less；Because the degree of lignification of bagasse is higher, there is the reasons such as silicified cell in stem epidermis, its be all difficult to for a long time by
Effective trans-utilization, often goes out of use without or being only simple as fuel, utilization rate is very low, not only causes resource
Waste, but also bring the pollution of environment.
In the last few years, there is scholar that bagasse is produced into activated carbon, and for the adsorption treatment of heavy metal waste water, achieved one
Fixed effect.But, bagasse active carbon has that absorption stability is bad, intensity is not high, absorption property one in use
As the problems such as, so as to constrain the use of bagasse active carbon.
The content of the invention
There is provided one kind for the deficiency existed present invention aim to address the activated carbon prepared in the prior art using bagasse
The method that activated carbon is prepared using bagasse, its decoloring ability is strong, and stability is good, and intensity is high, safety non-toxic.
Technical scheme
A kind of method that utilization bagasse prepares activated carbon, comprises the following steps：
(1) crushed after bagasse is dried, be then added in sodium carbonate liquor and soak 10-20h, the bagasse after drying
Weight ratio with sodium carbonate liquor is 1:3-6；
(2) bagasse after immersion is dehydrated, is subsequently placed in Muffle furnace and carries out charing process, obtain carbide；
(3) by carbide chlorohydric acid pickling, then neutrality is washed to, finally dries and sieve, produce.
Further, in step (1), the drying temperature is 105-110 DEG C.
Further, in step (1), the sodium carbonate liquor concentration is 1-3mol/L.
Further, in step (1), the weight ratio of bagasse and sodium carbonate liquor after drying is 1:4.
Further, in step (2), the charing process temperature is 450-550 DEG C, and the time is 2-4h.
Further, in step (3), the sieving was 100 mesh sieves.
Beneficial effects of the present invention：The present invention uses bagasse for raw material to prepare activated carbon, is not only solution bagasse
Recycling, avoid the waste and environmental pollution of resource from providing effective way, and bagasse is a kind of safety non-toxic in itself
Recyclable organism material, sugar industry can be directly used for by its activated carbon prepared, added value of product is high, can produce
Good social and economic benefit, and the activated carbon decolorizing ability of the present invention is strong, and stability is good, and intensity is high, safety non-toxic.
