Abstract
A catalyst includes a platinum coating deposited on a silica support. The support has an average surface area between about 100 m/g and about 120 m/g. The platinum coating is between about 5 wt % and about l5 wt % of the catalyst. The combination of the selected surface area, silica support, and selected amount of platinum coating provides a catalytic activation temperature below 200° C. and avoids the formation of NO.
