Platinum catalyst (1% loading) on alumina support was prepared by incipient wetness method. A solution of tetraamine platinum (II) nitrate was added to the dry support (alumina) to make dough and then converted into pellets. The pellets were dried in an air oven at 120�C for 24hr, followed by calcination in air in a tube furnace at 500�C for 2hr. The catalyst was characterized by pulse chemisorption (Micromeritics, Chemisorb 2705) equipment to determine % dispersion of Pt on alumina support. The dispersion of platinum was 28%. Hydrogen TPD data showed continuous TCD signals indicating evolution of hydrogen gas at higher temperature range (500-900�C). The preparation of the platinum catalyst in silica support, characterization and activity studies are being conducted. The comparative data on three catalysts (Pt, Pd and Ru) will be presented .
