Technology Converting Coal to Liquid Fuels

Universities in South Africa are generally renowned for research rather than innovation. But the University of the Witwatersrand in Johannesburg made waves when they developed a technology to convert coal to liquid fuels and electricity. The pilot plant has been running successfully in China since 2008.

If I'm not mistaken, the largest input to make this happen is heat. When converting coal to syn-fuel 2/3rds of the coal goes into making the heat and 1/3 toward the fuel itself. If the heat input came from high-temperature nuclear, the entire process would be an order of magnitude more efficient and cleaner.

This would be a good time to start putting these into practice in South Africa

I remember hearing about germany doing something similar in ww2 as it was lacking enough fuel for its wars

Hoi4 Axis players

The Germans of WW2 had to use it.

And where / how do you get the syngas?

Now imagine countries which have a low GDP using the coal the naturally have to turn into gasoline which doesn't even need to be refined as it's a pure molecular form, to then use it for themselves to become self sufficient but also be able to sell it on a global scale to then begin to sustain the national economy by using a chemical process which also helps the environment as it continues the natural food chain of auto trophic producers absorbing the harmful carbon dioxide emissions and thus, we just saved the world from climate change. Yes Harvard, I'd take the scholarship now please.

Use the carbon dioxide to produce a starchy plant. Make alcohol. Vacuum distill that. Use the fuel to run generators. Why the vacuum? It takes far less energy to separate the alcohol from the water. Conservatively you only need 80% to burn. Also what about vertical farming. Plants love CO2.

Could you share the p&Id for this skid.

Very interesting, I will contact you in regard to this work, Dan

I have a question: can we use ammonia to totally replace the carbon chains? Or even dimethyloaether? P.S. Carbon dioxide is good! It is plant food and fossil fuels made the planet greener !!!

Dry ice, turbine, genarator? A dash of water.

The reason why South Africa went this route was because of the oil embargos and economic sanctions placed on South Africa during its Apartheid Era. This video was done in 2010. Fast forward to 2019 and the world is slowly moving toward electrification of transit (electric vehicles - electrek.co, electricauto.org) powered by renewables (wind and solar). US policy makers were talking about this back in the late 70's after the OPEC and Iranian oil embargos. Today coal is on the way out and there is a surplus of oil on the market. Peak oil production may reverse this but the practical solution would be greater use of fracked shale oil, tar sands and deep water reserves (mind you all of these are environmentally problematic and capital intensive). Biofuels (diesel from algae, ethanol from waste products) currently do not have the economies of scale to replace conventional oil. This solution was undertaken under emergency and under duress. Germany in the waning days of WWII and South Africa under Apartheid.

Germans doing it since 2WW. Hahaha)
-
yes i love liquid fuels!!!!!!!!!!!!!!!!
-
South africa was first to do this not Germany
