Synthetic Fuel Production Method

US Patent:
6558442, May 6, 2003
Filed:
Aug 24, 2001
Appl. No.:
09/939229
Inventors:
Paul Donovan - Parsonsfield ME
William Tis - Verona PA
Assignee:
Entac, Inc. - Parsonfield ME
International Classification:
C10L 902
US Classification:
44620, 44628, 44542, 44545
Abstract:
A process of making coal fines into a commercially viable fuel product using tall oil and tall oil pitch emulsions. The tall oil based emulsions are sprayed into, and reacted with, the coal fines, resulting in a cost effective and industry-usable source of synthetic fuel.

Synthetic Fuel Production Method

US Patent:
7147679, Dec 12, 2006
Filed:
May 5, 2003
Appl. No.:
10/429343
Inventors:
Paul Donovan - Parsonsfield ME, US
William Tis - Verona PA, US
International Classification:
C10L 5/00
US Classification:
44620, 44564, 44579, 44607, 44628
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.

Synthetic Fuel Production Method

US Patent:
2004004, Mar 18, 2004
Filed:
Sep 11, 2003
Appl. No.:
10/660259
Inventors:
Paul Donovan - Parsonsfield ME, US
William Tis - Verona PA, US
International Classification:
C10L005/44, C10L005/14, C10L005/00
US Classification:
044/500000, 044/573000
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.
