TECHNOLOGY FOCUS - BIOLOGY - Preferred Components: The biomass comprises starch, cellulose, hemicellulose, lignin and/or lignocellulose. The biomass has a dry matter content of at least 85 (preferably at least 95) wt.%. The biomass comprises at least one type of annual plant. The biomass is a hemp or a biomass mixture comprising hemp.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: The method further comprises another step (c) fractionated distillation of the fuel produced in (b). The step (a) is performed by chemical decomposition of the biomass in a solvent of: supercritical water, a superacid, hydrazine, ammonia and/or amine; and dry and pressurized ammonia, supercritical water, a dry and pressurized amine, or a dry and pressurized hydrazine. The step (b) is performed by reacting the first solution with a reducing agent of hydrogen sulfide, white phosphorus, hydrazine or a hydride containing silane. The step (a) is performed by chemical decomposition of the biomass in dry and pressurized ammonia or supercritical ammonia and the step (b) is performed by reacting the first solution with a reducing agent, which is sodium, potassium, calcium in dissolved and/or melted form or sodium hydride, potassium hydride and calcium hydride. The average temperature for performance of (a) and (b) is below 220 degrees C, preferably below 190 degrees C. The undesirable substances are removed before or in (a) and/or (b). The undesirable substances are removed before or in (a) comprises molecules containing nitrogen and/or sulfur. The fuel is fractionated out from (c) is bioequivalents to diesel, an Otto fuel and/or a jet fuel, which are equivalents with reference to a combustion point of view. The fuel is fractionated out from (c) comprises at least 95 wt.% of 2,2,4-trimethylpentane. Preferred Components: The hydride containing silane is diethyl silane or n-butyl silane. The chemical intermediate compound is at least one of: glucose, maltose and/or cellobiose; and p-coumaryl alcohol, coniferyl alcohol and/or sinapyl alcohol. The hydrocarbon produced in (b) is at least one of an alkane and/or alkene. The at least one phenol or other alcohol, having from 6-20 carbon atoms, is produced in (a) as the optional target chemical. The at least one hydrocarbon produced in (b) are at least one of an alkane or alkene having 8 carbon atoms. The fuel is produced in (b) comprises at least 90 (preferably at least 95) wt.% of at least one alkane having 8 carbon atoms. EXAMPLE - None given.
