| Interesting read. I had two questions. First, does this technology offer a means for extended processing of coal deposits that were previously mined, but where low yeilds left large amounts of material unmined and/or unprocessed. Second, I am not sure about the meaning of the reference "dry coal". It implies some sort of ore improvement process that "upgrades" the raw material to a higher fuel quality. Presumably, this is done by using the technology to remove moisture (water) bearing hydrocarbon content or oils from the ore and them reclaiming them in liquid form. The statement about cleaner fuel implies that this same process has some sort of purification effect on the oils obtained in this manner.
One other observation regarding your comment after the quote. True, the CO(2) is still present, but the process appears to remove coal impurities in a localized manner that would make filtering and capture of impurities somewhat more practical and affordable.
