Abstract
This invention relates to a method and apparatus for gasifying or liquifying coal. In particular, the method comprises reacting a coal with a molten aluminum or aluminum alloy bath. The apparatus includes a reaction vessel for carrying out the reaction, as well as other equipment necessary for capturing and removing the reaction products. Further, the process can be used to cogenerate electricity using the excess heat generated by the process.
Claims12
A method for producing liquefied products from solid coal particles, the method comprising:
- injecting a stream of coal into a molten metal in a reaction vessel at a sufficient distance below the upper surface of the molten metal for mixing the coal into the molten metal;
- reacting the stream of coal with the molten metal to produce a liquefied product;
- separating, by settling, the liquefied product from the molten metal within the reaction vessel;
- removing the liquefied product from the reaction vessel through a lower outlet in the reaction vessel;
- removing reaction gas from the reaction vessel;
- and
- removing particulate matter from the reaction gas using a separator.
