Anthropomorphic global warming? Heh. Anyway, catalytic converters don't interact with global warming at all.

Catalytic converters don't have any effect on CO2, if anything they make it worse by requiring stoichiometric mixture instead of lean. The purpose of catalytic converters is to reduce smog. Airplanes, in principle, spend most of their time flying at altitude and over rural areas where smog is not a factor.

By far the biggest reason not to have one is that leaded gas fouls catalytic converters and so with typical avgas they would quickly just turn to heavy, expensive junk. I suppose if you guaranteed to only ever run mogas you could consider it, but still you would just be adding weight, cost and complexity for very little actual benefit.

Subject: [FlyRotary] Catalyst in an aircraft application

Good afternoon all,

In this day and age of EPA, pollution control, green earth, etc., I wondered about the viability of an exhaust catalyst in an aircraft application. Are there any reasons not to use a catalytic converter in this capacity? Weight? Exhaust restrictions? Other?

Many thanks and looking forward to your feedback.

Best regards,
Chris

How about all of the above, and additionally expense! Some people really don't care what they spend on their plane, I do! The engineer in me also begs me to ask if the alteration of hydrocarbon to another chemical in the atmosphere is really helpful AT ALL. Most "environmentalists" are ignorant idiots and the sooner we start listening to real scientists as opposed to paid "advocates" I'll feel a lot better about it. Anthropomorphic global warming is BS, get over it. Sorry for the rant.
