Well little one, Secunda CTL is a type of technology that helps make fuel out of things like coal or oil. Do you remember what fuel is? It's what we put in cars, trucks and airplanes to make them go.
So, with this technology, we take something called a feedstock, which is usually coal or oil, and then we heat it up really hot with something called gas. This process is called gasification.
Once we heat up the feedstock, it turns into something called synthesis gas or syngas for short. This syngas is then cleaned up and processed further to make different fuels like diesel, gasoline or even jet fuel.
The really cool thing about Secunda CTL is that it's a way to turn something that we already have a lot of, like coal or oil, into something else that we can use. And, since there's a lot of coal and oil in the world, this technology can be really helpful in making sure we always have enough fuel for the things we need to do.
