Could on-vehicle CO2 catalysis cut down on global warming? [View all]

This is done over one of several catalysts:

2CO₂ -> 2CO + O₂

Or in English, carbon dioxide dissociates into carbon monoxide and oxygen. Chemical plants that make things from carbon monoxide (a LOT of things are made from it) run the smoke from their heat sources across catalysts, recover the CO and use it in their processes.

Now, here's my idea: since carbon monoxide is a fuel gas, why couldn't they put a catalyzer in the exhaust system of a car and feed the carbon monoxide into the intake manifold?

Because of thermodynamics. jeff47 Dec 2015 #1

So exhaust heat wouldn't be enough to activate a catalyst? jmowreader Dec 2015 #2

Catalysts aren't things that get "activated". jeff47 Dec 2015 #5

I'm not thinking about cutting fuel consumption here jmowreader Dec 2015 #7

If you aren't cutting fuel consumption, you're producing more CO2. jeff47 Dec 2015 #10

I apparently am missing the point. lumberjack_jeff Dec 2015 #3

Of course it does jmowreader Dec 2015 #9

I'd be rather concerned abot CO leaks into the vehicle KamaAina Dec 2015 #6

I thought about that...putting the reactor in the engine compartment would help jmowreader Dec 2015 #8
