pellet reaktivasi 3 jam dan pellet reaktivasi 6 jam. Data adsorpsi isotermal yang

Dari hasil penelitian didapat bahwa kapasitas penyerapan (adsorpsi) karbon aktif
berbentuk pellet lebih baik dibandingkan karbon aktif bentuk granular, hal
tersebut dikarenakan setelah dilakukan reaktivasi terjadi peningkatan kandungan
unsur karbon (C) dan pengurangan unsur-unsur pengotordalam karbon aktif
bentuk pellet. Kapasitas adsorpsi hidrogen maksimum terjadi pada karbon aktif
pellet dengan reaktivasi 3 jam yaitu 0.0027261kg/kg pada temperatur -50C dan
tekanan 3899.54kPa, sedangkan untuk karbon aktif pellet reaktivasi 6 jam
adalah0.0020384kg/kg pada temperatur -5oC dan tekanan 3897.501 kPa. Untuk
karbon aktif pellet reaktivasi 1 jam adalah 0.0016873kg/kg pada temperatur -5oC
dan tekanan 3854.83kPa dan untuk karbon aktif granular (as received) adalah
0.0014779kg/kg karbon aktif pada temperatur -5oC dan tekanan 3869.19kPa.

<b>Abstract</b><br>
One alternative of hydrogen storage by adsorption method is using activated
carbon, because it has a large adsorption capacity associated with a surface area
and size of pores. To enhance the adsorption of the adsorbent can be done by
making as many pores which include categories micropori to fit the size of the
hydrogen molecule as an adsorbate. With a growing percentage of micropore
compared with its macropori and mesopori, then the adsorption capacity of
adsorbent is expected to increase. How that is done to it is by making nano-sized
particles through ball-milling process and then formed into solids (pellets) through
the mechanical suppression by the addition of lignocellulose as a binder liquid.
From the results of this study found that the mixing between the liquid and
powder lignocellulose nano particle to form pellets of activated carbon is suitable
for use in a 3:4 ratio, because after the reactivation process with three variations
of the time is 1 hour, 3 hours and 6 hours , the form of activated carbon pellets
remained stable.
The ability of hydrogen adsorption on activated carbon pellet form is known
through testing using the volumetric method with a variation of isothermal
temperature-50C and 350C and pressures up to 4 MPa respectively to granular
activated carbon (as received), pellets reactivation 1 hour , pellets reactivation 3
hours and pellets reactivation 6 hours. Adsorption isotherms data obtained is the
data capacity of hydrogen absorption on any form of activated carbon and on any
variation of pressure and isoterms temperature , then plotted in the graph the
relationship of pressure and absorption capacity.
From the research results obtained that the absorption capacity (adsorption)
activated carbon pellets better than the granular activated carbon, it is because
after the reactivation there is increasing of the content of carbon (C) element and
reduction of the impurities elements in the pellets activated carbon. Maximum
capacity of hydrogen adsorption on activated carbon pellets occur with
reactivation of 3 hours is0.0027261kg / kg at a temperature -50C and the pressure
is3899.54kPa, while for the reactivation of activated carbon pellets 6 hours is
0.0020384kg / kg at a temperature -5oC and the pressure is 3897,501 kPa. For
reactivation of activated carbon pellets for 1 hour is 0.0016873kg / kg at a
temperature -5oC and the pressure is 3854,83 kPa and for granular activated
carbon (as received) is 0.0014779kg / kg of activated carbon at a temperature of-
5oC and the pressure is 3869,19 kPa.
