Abstract
The present invention relates to a method for producing active carbon, which adopts fruit shells of wild bead trees as raw materials, and then, the raw materials are soaked, carbonized and activated.
Description
The invention belongs to the manufacture method of gac, in more detail, be to utilize the margosa shell to be raw material, by 10% liquor zinci chloridi soak, dry, 350 to 400 ℃ of charring furnace carbonizations, 1000 ℃ of activation furnace activation, pickling, washing, baking procedures carry out the method field that gac is made.
Margosa is a kind of wild plant, and only just there are more than 300 ten thousand strains in Cao County, Shandong Province, and annual result has 6,000 ten thousand to 8,000 ten thousand jin, never obtains utilizing.The margosa shell is hard, and dense structure can make the gac of porosity prosperity, because of containing making the useful Kuliansu of gac, is the good raw material of making top-grade active carbon in the margosa shell, but does not obtain development and use so far.
Purpose of the present invention is to utilize the margosa shell to make process of active carbon for raw material.
The present invention adopts following step to reach and realizes purpose of the present invention.A), in 10% liquor zinci chloridi, soaked 8 hours the margosa shell of pulverizing 40 mesh sieves.B) with the method for centrifugation, the margosa shell is separated with liquor zinci chloridi.C) dry margosa shell to water content naturally and be lower than 35%.D) the margosa shell was moved in 350 to 400 ℃ the carbide furnace carbonization 8 hours.E) the margosa shell after carbonization is transferred in 1000 ℃ the activation furnace, activates 10 to 15 hours, f) after the activated step, adopts the general same procedure of making gac, carries out pickling, washing, baking procedure.(pickling: will activate the charcoal material and immerse 10% hydrochloric acid soln, and heat to 60 ℃, and fully stir, ash content and impurity are all dissolved, washing: is 7 with 60 ℃ of boiling water flushing activation charcoal material to the pH value, centrifuge dripping activation charcoal material.Oven dry: the activation charcoal material after the dehydration, still contain 50% moisture, oven dry is 2 hours under 150 ℃ of temperature, is warming up to 600 ℃ then, keeps 4 hours again, is active carbon finished products after coming out of the stove.
In order to further specify the present invention, below for an embodiment:
Taking by weighing 100 kilograms of clean margosa shells by 40 mesh sieves soaks, separates, dries, after the carbonization, activation, pickling, washing, baking procedure, obtains 20 kilograms gac according to the step of introducing above of the present invention.
Utilize margosa shell production process of active carbon according to the present invention, its performance index are compared with standard index and are listed in the table 1
Table 1 is the synopsis of detected result of the present invention and standard index:

Standard index in the table 1 is the Ministry of Chemical Industry of the People's Republic of China (PRC) that announces according to HG3-1290-80, gac, ministerial standard, detected result is the test event index that the present invention detects, the gac that utilizes the margosa shell to make as can be seen from Table 1, the main performance index adsorptive capacity is greater than ministerial standard.Gac constructed in accordance provides chemical plant, Jining, Shandong to do epoxy chloropropane discoloring agent usefulness, and effect is remarkable.
Therefore, provided by the present invention is a successful method with China tree shell manufacturing active carbon method.
Claims (1)
