I burn anthracite in my woodburners. You can buy it in pellet form usually called nut coal. It is the hardest coal with the highest carbon content. It burns clean. But it only comes from a small area in Pennsylvania and probably less than 1% of US production.
Bituminous and subbituminous are what are usually burned for producing electricity. They are far more commonly found and therefore cheaper.
Lignite is used for electricity production in the US but at a rate of under 10%.
I remember learning about these in maybe the third grade when learning about dinosaurs and the carboniferous era. I also am familiar because lignite can be found in concrete mixes (I am a concrete contractor) and through my use of wood and coal heat in my house and pole barns.
I went to a Catholic school when that was still a meaningful distinction. When we moved from the city to a more rural setting I changed to public schools. This was in 1976 and I was in 6th grade. They were nearly 2 years behind what I had been doing. I had to go to the HS to take algebra in 7th grade. The kids in my school had no idea what that was. I had been doing story problems since the third grade.

I never learned about that when I was a kid.
