Converting carbon dioxide into chemicals

Degasified coal? Bitumen? Will we have to turn to these at the cost of global warming?

Converting carbon dioxide into chemicals

Post by Cycloloco »

I have previously said chemists can make hydrocarbons from carbon dioxide. See

Now there is a bit of easily accessible evidence.

On 27th July 2006 the Royal Society of Chemistry held a one-day workshop on making chemicals from CO2. It was fully subscribed and I didn't get in but the summary on their website gives a lot of info. There are 8 PDF files, some of general interest and some of detailed chemistry. See

I can see a time when smaller coal/biomass-fired power stations have their CO2 effluent used for chemicals with surplus heat from the power station used as process heat. Not to be added to current sites like Drax but on smaller stations on existing brownfield sites.

This will not deal with all CO2 effluent or loss of fossil oil but it could become a useful supply of hydrocarbons.

That depends on where the energy comes from to do it. The conversion to HCs will not be 100% energy efficient, and all ways we have of burning HCs are not 100% efficient, so it represents a drain of energy. If the energy used to run the process was "waste" heat, then maybe it would be useful, but if it's high-grade heat, or electricity, then it represents a new inefficient way to power our cars for a year or two longer. :)
