Some clean coal research going on in Japan. The Ashless Coal (Hyper-Coal, HPC) caught my interest. Up to 70% yield from Bituminous coal with less than 200ppm ash content. That's 0.02%!!! Burn a ton and make less than 1/2lb ash.

They actually built a "benchscale unit" that does 0.1Tons/day and tested various Bituminous coal types. There's production ramp/scaling that show 5000Tons/day production. This is targeted for industrial use but I see no reason why it couldn't be made for consumer/home use. Imagine a coal stove, boiler or furnace without an ashpan? How long before the treehuggers kill this one?

Being the pessimist, I'm sure thats assuming no bone or impurities. I can't imagine a fire hot enough to turn that stuff to vapor. I bet theres ALOT of fly ash. :shock:

Edit: the slide show says the "Insoluble Coal" IE: Fly-ash, insoluable matter are seperated in the process. So I am assuming what come out, AFTER the impurities and ash is removed, is THEN ash-free.

The way I read it... Bituminous is subjected to a solvent/heating process which yields:

  1. Hyper-Coal (200ppm ash content)
  2. Insoluble Coal (usable but with much higher ash content than the initial Bituminous)
  3. Solvent (recoverable)
I would think the Hyper-Coal will burn almost completely clean and would be easy to ignite... No?

I would agree with that statement.
