  • Patent number: 7147679
    Abstract: A method of producing a synthetic fuel by treating fines of bituminous coal with an emulsion of a tall-oil mix, which may include enhancers that either increase the chemical change in the coal or reduce the cost of the synthetic fuel. Enhancers include poly vinyl acetate (PVA) and/or ethyl vinyl acetate (EVA), glycol, lignosulfonate, beet sugar bottoms, corn bottoms, brewery bottoms, vegetable tall oil, vegetable oil, and/or spent frying oil. The emulsion is sprayed into, and reacted with, the coal fines, resulting in a cost effective and industry-usable source of synthetic fuel.
    Type: Grant
    Filed: May 5, 2003
    Date of Patent: December 12, 2006
    Inventors: Paul Donovan, William Tis
  • Publication number: 20040049973
    Abstract: A method of producing a synthetic fuel by treating bituminous coal fines with a tall-oil mix that may include enhancer additives that either increase the chemical change capability of the tall-oil mix or reduce the cost of the tall-oil mix while maintaining the chemical change rate, and/or an additive of tar decanter sludge and light cycle oil. Enhancers include poly vinyl acetate (PVA) and/or ethyl vinyl acetate (EVA), glycol, lignosulfonate, beet sugar bottoms, corn bottoms, brewery bottoms, vegetable tall oil, vegetable oil, and/or spent frying oil. The tall-oil mix is reacted with the coal, resulting in a cost effective and industry-usable source of synthetic fuel. When the enhanced tall-oil mix is reacted with bituminous metallurgical coal, the product is a synthetic fuel.
