A Waste Gasification Plant In a Truck

Posted January 20, 2009 8:38 AM

From Slashdot:

There are plenty of waste-to-energy plants around the US, but most of them simply burn the waste, dumping carbon dioxide into the atmosphere. Gasification technology, by contrast, converts nearly all of the waste into gases like hydrogen and carbon monoxide that can be used to run generators and furnaces. The problem is that most gasification facilities are factory-sized. Now a startup outside Boston has built a combination shredder-dryer-pelletizer-gasifier that fits into 30-by-8-by-8-foot shipping container.

Cool thing!

But "carbon monoxide" is used to run generators? I must have missed something along the way. I thought CO was a waste that was not-so-friendly because it poisons people when they breathe it. The loose negative charge bonds to blood oxygen and causes asphyxiation eventually.

How is it used in generators? Or is it furnaces? I didn't think CO was very flammable.

I think it (CO) is used in furnaces to create a reducing atmosphere. I, like you, am not sure of the flammability except I think it was used in the early century for lighting and was called Water Gas. Anyway, I don't know how this would help with Global Warming since it, CO, has a propensity to bond with available O2, as you mentioned by leaching it from any local human or, I assume, the air. What do you have then? CO2 the BIG culprit in "Global Warming".

The oxidation of CO into CO2 releases heat and is a half reaction. In short CO is a flammable gas which is another risk factor apart from the toxicity when it is created by spontaneous combustion of coal or biomass.
