...most common process, coal is heated under great pressure to 900° F. As the coal decomposes, it releases oil and gas. Another extraction method, which adds hydrogen to coal that is heated under pressure, will be tested at a small, experimental plant operated by several oil companies in Catlettsburg, Ky. It should be able to convert 600 tons of coal into 1,800 bbl. of oil a day. At a DOE-funded plant in Fort Lewis, Wash., Gulf Oil since 1974 has been testing yet another process called "solvent refined coal," which uses chemicals to remove impurities from...
...street lights last century were powered by coal gas, and during World War II Germany fueled its planes and tanks with coal oil. The conversion involves heating the coal to very high temperatures under high pressure so that it decomposes and gives off oils, carbon monoxide and hydrogen gases, which then have to be passed through a catalyst and cleaned of impurities...
...another reprocessing plant. In Denmark, officials announced they were rethinking their plans for new plant construction, and in Sweden the atomic energy inspection board reported that two nuclear reactors similar to the one at Three Mile Island would have to be retrofitted with systems that would deflate any hydrogen gas bubbles...
...been promptly restored. (Explained one supervisor later: "I thought I completed that.") 2) A light that warned of the water shut-off was not seen for eight minutes because it was blocked by a tag hanging from a switch above it. 3) The first indication of real trouble, a hydrogen explosion during the first few hours of the accident, went unnoticed by federal inspectors even though a recording gauge registered it. The staff of the Nuclear Regulatory Commission later confirmed that such human errors turned what might have been a minor malfunction into a major breakdown...
...admitted that it may have overestimated the seriousness of the large hydrogen bubble that formed in the reactor vessel. Despite that small explosion, investigators now believe there was never any danger of a bigger blast, which could have ruptured the reactor vessel and containment building, spreading deadly radiation. The false alarm was caused by incorrect speculation about free oxygen in the vessel...
