Abstract
The objective of this research is to investigate the performance of catalytic combustion of hydrogen by using Pt/Al O in different weight loading catalyst ranged from 0.06 to 0.2 gram in assisting the catalytic combustion of methane experimentally. 1 wt% and 3 wt% platinum catalyst used to determine the performance of catalytic combustion of hydrogen. The platinum supported with alumina to increase the area of platinum to faster the reaction and to reduce cost. The behavior of hydrogen has been studied accordingly based on their auto ignition in room temperature and atmospheric pressure when contact with platinum with air in the range of lower and upper flammability limits. Sets of range from 72% to 97% fuel to air ratio were used for the experiment. Different weight loading of catalyst and catalyst weight percent of Pt in alumina gave various performances and the effect of air/fuel ratio was observed as well to get the best result. The catalytic combustion of hydrogen was a complete combustion and could reach up to 450°C. The experiment held in vertical single bed reactor whereby the exit temperature of catalytic combustion of hydrogen was recorded for performance comparison. The best performance was hydrogen flow rate set to 772.8 ccm and air set to 272.16 ccm with 1wt% Pt and weight loading 0.1gram which gave temperature of 459°C because the effect of larger surface reaction.
