Abstract

The invention provides an alternative filet composition and methods of preparing and using the composition. The alternative fuel can comprise coal, or another combustible solid, and one or more components selected from a group consisting of sugar solutions, tall oil, black liquor, vegetable oils, animal fats, triglycerides, methyl esters, ethyl esters, crude glycerin by-product and fatty acids.

Claims

exact text as granted — not AI-modified
1 . An alternative fuel comprising one or more combustible solids and one or more liquid hydrocarbon components selected from a group consisting of sugar solutions, tall oil, black liquor, vegetable oils, animal fats, triglycerides, methyl esters, ethyl esters, crude glycerin by-product and fatty acids, provided that when the liquid hydrocarbon component is vegetable oil, the combustible solid is other than a cellulosic powder and further provided that when the combustible solid is coal, the liquid hydrocarbon component is other than sugar solutions. 
     
     
         2 . The alternative fuel of  claim 1  comprising about 0.1 to about 49 weight percent of said liquid hydrocarbon components. 
     
     
         3 . The alternative fuel of  claim 1  wherein the combustible solid is selected from coal, wood chips, coke, and garbage. 
     
     
         4 . The alternative fuel of  claim 3  comprising about 0.1 to about 25 weight percent of said liquid hydrocarbon components. 
     
     
         5 . The alternative fuel of  claim 3  wherein the methyl esters, ethyl esters, crude glycerin by-product and fatty acids are derived from transesterification reactions involving triglycerides. 
     
     
         6 . The alternative fuel of  claim 3  wherein the methyl esters, ethyl esters, crude glycerin by-product and fatty acids are derived from a biodiesel manufacturing process. 
     
     
         7 . The alternative fuel of  claim 3  wherein the combustible solid is coal. 
     
     
         8 . The alternative fuel of  claim 3  wherein the liquid hydrocarbon is a crude glycerin by-product of the biodiesel process comprising about 5 to about 30 weight percent methanol. 
     
     
         9 . The alternative fuel of  claim 8  wherein the crude glycerin by-product comprises about 30 to about 95 weight percent of glycerin. 
     
     
         10 . The alternative fuel of  claim 1  wherein the combustible solid is fatty acid by-product. 
     
     
         11 . The alternative fuel of  claim 10  further comprising about 30 to about 70 weight percent crude glycerin by-product. 
     
     
         12 . The alternative fuel of  claim 10  wherein the solid alternative fuel is heated to increase flowability. 
     
     
         13 . A method of preparing an alternative fuel comprising applying one or more liquid hydrocarbon components selected from a group consisting of sugar solutions, tall oil, black liquor, vegetable oils, animal fats, triglycerides, methyl esters, ethyl esters, crude glycerin by-product and fatty acids to one or more combustible solids, provided that when the liquid hydrocarbon component is vegetable oil, the combustible solid is other than a cellulosic powder and further provided that when the combustible solid is coal, the liquid hydrocarbon component is other than sugar solutions. 
     
     
         14 . The method of  claim 13  wherein about 0.1 to about 49 weight percent of said liquid hydrocarbon components is applied to said combustible solids. 
     
     
         15 . The method of  claim 14  wherein the combustible solids are selected from coal, wood chips, coke and garbage. 
     
     
         16 . The method of  claim 15  wherein about 0.1 to about 25 weight percent of said liquid hydrocarbon components are applied to said combustible solids. 
     
     
         17 . The method of  claim 14  wherein the methyl esters, ethyl esters, crude glycerin by-product and fatty acids are derived from transesterification reactions involving triglycerides. 
     
     
         18 . The method of  claim 14  wherein the methyl esters, ethyl esters, crude glycerin by-product and fatty acids are derived from a biodiesel manufacturing process. 
     
     
         19 . The method of  claim 14  wherein the combustible solid is coal. 
     
     
         20 . The method of  claim 19  wherein the liquid hydrocarbon is a crude glycerin by-product of the biodiesel process comprising between about 5 and about 30 weight percent methanol. 
     
     
         21 . The method of  claim 20  wherein the crude glycerin by-product comprises between about 30 and about 95 weight percent of glycerin. 
     
     
         22 . The method of  claim 13  wherein the combustible solid is a fatty acid by-product. 
     
     
         23 . The method of  claim 22  wherein the alternative fuel further comprises between about 30 and about 70 weight percent crude glycerin by-product. 
     
     
         24 . The method of  claim 22  further comprising the step of heating the alternative fuel to increase its flowability.
