Sound like MAYBE it's a "pre-converter", or "light-off" converter. It takes a while for the main converter to get up to operating temperature, so car makers put a smaller converter as close to the engine as they can, to help heat up the exhaust, and "light-off" the main converter sooner.

Exactly where did you see this term?
Right now it sounds like a "pre-cat", one that deals only with hydrocarbons and carbon monoxide, but not nitric oxide.
A three-way cat would handle all of HC, CO and NO.
