| Summary: | 碩士 === 國立中央大學 === 環境工程研究所碩士在職專班 === 95 === This research utilizes a little brilliant cellulose composing type pharmaceutical waste material of the chemical pharmaceutical factory to carry on carbonization and produce and make activated carbon in the cracked stove, the cracked stove adopts the nitrogen (N2) The atmosphere, with intensifying the operation condition of time regularly. Turn time into the experiment parameter with carbonization temperature, carbonization time and temperature of activating and livingly, with ultimate analysis, BET than surface area, size of hole and characteristic of distributing, the operation condition of probing into cracked stove is to the influence of carrying on recycle treatment of activated carbon of a little brilliant cellulosic waste material, put forward the best carbonization condition and activate the condition; And to the heavy metal (Cu, Pb) with the activated carbon Absorb it test,look over by activated carbon it last function.
In carbonization experiment, the output lies between 10.1-14.6%, the output and carbonization temperature and carbonization time present and shoulder dependence; Carbonization temperature, time and presenting dependence in the hope of being improved than the surface area are under the carbonization conditions of 900 degrees Centigrade of temperature and 120min, to reach than surface area most heavy activated carbon, average hole size lie between 1.83-1.93nm, hole diameter is it concentrate on 3-400nm to distribute, the capillary accounts for the volume of total hole and is up to 93.3%. In activating the experiment, the output lies between 10.2-13.3, the output and carbonization temperature and carbonization time present and shoulder dependence, activate temperature, time and present dependence in the hope of being improved more than the surface area, average hole size lie between 1.91-1.96nm, hole diameter is it concentrate on 3-400nm to distribute, capillary account for total hole volume up to 94.5%; In ultimate analysis, will produce bigger change to C and H before and after splitting decomposition, but S and N had little change, C and the content is reduced as cracked temperature rises, but it is not high to change the range. So best activated carbon for carbonization of 900 degrees Centigrade in temperature, carbonization time 120min prepared terms, with activating 900 degrees Centigrade of temperature, activating time 120min. This research utilizes activated carbon to absorb the way at the same time, predict the heavy metal absorbs the degree, the result shows the theory way predicts that gets good verification with the experimental analysis one.
