Technical field
The present invention relates to active carbon preparation, in particular to a kind of preparation methods of high absorption property peach kernel shell active carbon.
Background technique
Active carbon is a kind of carbon material, and surface is black and is made up of carbonaceous material, is had huge
Outer surface and intensive hole, are consequently formed superpower adsorption capacity.It is existing it is industrial production active carbon raw material be mostly coal,
The derivative of coal and non-renewable resources etc., preparation expense is relatively expensive, and the sources of raw material are relatively deficient and prepare
Process contamination is relatively more serious, and during using existing activated carbon adsorption pollutant, existing activated carbon adsorption performance
It is not good enough, so that the consumption of active carbon is big, so that required expense also increases with it.Therefore, at low cost, adsorption energy is searched out
The good active carbon of power prepares raw material and has become a top priority.
Summary of the invention
To solve the problems mentioned in the above background technology, the purpose of the present invention is to provide a kind of high absorption property peach kernels
The preparation method of shell active carbon, preparation method is simple, and material easily obtains, and promotes the resource utilization of peach kernel shell, and it is useless to reduce solid
The generation of gurry.
In order to solve the above technical problems, technical solution provided by the invention are as follows:
A kind of preparation method of high absorption property peach kernel shell active carbon, comprising the following steps:

2) the peach kernel shell washed is put into dryer and is dried, temperature is 100-150 DEG C, drying time 2-
4 hours；
3) by carrying out the peach kernel shell of drying to break removal peach kernel after Temperature fall；
4) H for the use of concentration being 35-40% by peach kernel shell obtained in step 3)2C2O4It carries out impregnating 8-12 hours and companion
With stirring, mixing speed 80-150r/min.
5) the peach kernel shell after immersion is put into heating furnace again and is activated, temperature is 350-400 DEG C, activation time 5-
7 hours；
6) Na for the use of concentration being 10-15% by the peach kernel shell after step 5) activation2CO3Impregnate 3-5 hours and carry out
Stirring；
7) it is cleaned up after doing the obtained peach kernel shell sunning of step 6) using clear water；
8) it will carry out being broken into production after the drying of walnut kernel that step 7) obtains and need granular size；
9) stored dry.
As an improvement, the H in the step 4)2C2O4Instead of middle strong acid with the same function.
As an improvement, the Na in the step 6)2CO3The NaHCO for the use of concentration being 40-50%3Replacement.
As an improvement, 8) the broken walnut kernel carries out sieving memory filtering, big particle be crushed from new, small
Concentration storage.
The beneficial effects of the present invention are:
Peach kernel shell method for preparation of active carbon of the invention is simple, using peach kernel shell as raw material is prepared, prepares specific surface area
It is huge, it is able to produce out the peach kernel shell active carbon of high absorption property, while promoting the resource utilization of peach kernel shell, it is useless to reduce solid
The generation of gurry, peach kernel shell has natural micropore, charcoal-stripped strong.
