Thesis for Bachelor Degree

Finally my thesis for bachelor degree has finished!!!!
A title for my thesis is Wet Mechanochemical Treatment on Coal-Based Activated Carbon for Hydrogen Storage.
Here is an abstract for my thesis:
Activated carbon from bituminous coal with submicrometer and nanometer size was developed for hydrogen storage materials. The purpose of this research is to increase the effectiveness of mechanochemical process on coal-based activated carbon sample used a planetary ball mill with ratio of carbon and KOH 1:1 and thermal activation process is not necessary. Activated carbon results from mechanochemical process will be made in the form of pellets with the addition of binder which is containing fructose, sucrose and oligo of by compacting. After mechanical milling process coal activated carbon obtained by the size of 414.7 nm which increased by 98.9%. Increasing the effectiveness of the hydrogen storage material can be seen from the increased capacity of adsorption of hydrogen at a temperature of-5 oC where there was an increase of ± 386.48 times and at a temperature of -25 oC there was an increase of ± 398.56 times compared with the untreated sample.
