Abstract
The invention discloses a method for preparing betel nut shell activated carbon. The method mainly includes the following steps: (a) selecting betel nut shells, cleaning and drying; (b) performing pre-carbonization on the betel nut shells; (c) activating; (d) carbonizing. The method provided by the invention selects renewable betel nut shells as a carbon source, therefore, the raw material is low in cost and wide in source range; the method meets the requirements of green chemical industry, forms a virtuous cycle with human life and nature, and promotes sustainable development of ecological environment; the activated carbon is reduced in production cost, better in mechanical strength, and application to the fields of scientific research and environmental protection.
Description
Technical field
The present invention relates to gac preparing technical field, be specifically related to be that gac prepared by raw material with PERICARPIUM ARECAE.
Background technology
Gac is a kind of conventional sorbent material, catalyzer or support of the catalyst, in each department of national economy and daily life, obtain widespread use.But, at present domestic prepare gac mainly with timber, fat coal etc. for raw material.This is also that gac makes the higher major reason of sorbent material cost, and then constrains its application in field of waste water treatment.Therefore finding the gac that activated carbon raw material cheap and easy to get prepares high-quality, reduce Activated Carbon Production cost, is the important channel advancing gac to apply at field of Environment Protection.
Summary of the invention
The object of this invention is to provide a kind of production method of PERICARPIUM ARECAE gac, this method solves the Utilizing question of PERICARPIUM ARECAE.Can its application in scientific research etc. of further genralrlization.
The present invention is that raw material is prepared gac and comprised the following steps with PERICARPIUM ARECAE:
A. raw material cleaning: choose high-quality PERICARPIUM ARECAE, after washing earth, then with distilled water rinsing repeatedly and put into the dryings of 60 DEG C of air dry ovens.
B. pre-carbonization: dried sample is put into retort furnace and be incubated the product that 30-60 minute obtains pre-carbonization at 300 DEG C.
C. activate: the product of pre-carbonization ground and to be immersed in concentrated alkali solution 1 to 2 day, then filter out alkali lye and dry.
D. carbonization: activation products are put into tube furnace and fire 3-4 hour in 700-800 DEG C under the atmosphere of nitrogen.
E. product treatment: after above-mentioned tube furnace returns to room temperature, with distilled water, carbonized product is washed till neutrality, PH ≈ 7, the air dry oven finally putting into 120 DEG C is dry, namely obtains finished product.
Further, in technique scheme, in described step b, the temperature rise rate of retort furnace is per minute 1-3 DEG C.
Further, in technique scheme, in described step c, described concentrated alkali solution is the NaOH of 10mol/L.
Further, in technique scheme, in described steps d, the temperature rise rate of tube furnace is per minute 2-4 DEG C.
Further, in technique scheme, the gac that described preparation method obtains, specific surface area 850-950m
