국내산 갈탄을 이용한 기상흡착용 활성탄 제조에 관한 연구(I)
A Study for Manufacture of Gas-adsorbent Carbons used Domestic Lignite(I)
Domestic lignite was mixed with the pitch and zinc chloride （as bINDER AND active agent） and molded it into the pallet form. And then, carbonization and steam activation were carried out through two separate processes.
In order to obtain optimum conditions in this process, the adsorptivities of the pallet carbons which were made in the various conditions （the time and temperature of carbonization and activation, the quantities of pitch and zinc chloride） were measured by CC14, I2 and phenol adsorption test.
The resulting conditions are as follows ;
（1） Carbonization = 700 ℃, 90 min
（2） Activation = 800 ℃, 60 min
（3） Zinc chloride quantity = 120 % (on the basis of the lignite)
（4） Pitch quantity = 30 % (on the basis of the lignite)
