| Summary: | ABSTRACT
Preparation,.characterization, activation,deactivation,and regenerationtests of CoO-MoO/ZnOand CoOMoO/
ZnO-ActivatedZeolite (AZ) catalysts for the hydrogen production using .steamreforming of alcohols in fusel oil
have been conducted. Both catalysts were prepared by impregnation of Co and Mo onto ZnO or ZnO-AZ powder
then followed by calcination at 400°C for 5 h under N2 stream: The BET method and pyridine adsorption were used
for catalysts characterization. The study of activation, deactivation, and regeneration of catalysts were conducted by
using steam reforming method in the semi flow reactor. The reaction condition were: weight ratio of catalystslfeed =
0.1, temperature: 450°C, duration: 45 min. Thegas product was trapped in a 250 mL vacuumpyrex bottle filled with
50 mL of 4 M NaOH solution and analyzed by GC with TCD system to determine H2existance and HCI titration to
determine C02 produced during the process that was dissolved in NaOH solution. The results showed that CoO-.
MoO/ZnO-AZ catalyst produced higher gas conversion than CoO-MoO/ZnOcatalyst. However, it had short catalyst
lifetime due to its high amount of coke deposited during the process. The regeneration test could enhance the
catalyst activity. The gas product consisted of H2(14.70%)and C02 (24.41%).
Keywords: fusel oil, steam reforming, deactivation, regeneration, hydrogen production.
