Production of fuel from chemicals derived from biomass
View Patent ↗Hydrocarbons may be formed from six carbon sugars. This process involves obtaining a quantity of a hexose sugar. The hexose sugar may be derived from biomass. The hexose sugar is reacted to form an alkali metal levulinate, an alkali metal valerate, an alkali metal 5-hydroxy pentanoate, or an alkali metal 5-alkoxy pentanoate. An anolyte is then prepared for use in a electrolytic cell. The anolyte contains the alkali metal levulinate, the alkali metal valerate, the alkali metal 5-hydroxy pentanoate, or the alkali metal 5-alkoxy pentanoate. The anolyte is then decarboxylated. This decarboxylating operates to decarboxylate the alkali metal levulinate, the alkali metal valerate, the alkali metal 5-hydroxy pentanoate, or the alkali metal 5-alkoxy pentanoate to form radicals, wherein the radicals react to form a hydrocarbon fuel compound.
1. An electrolytic cell comprising:
an anolyte compartment;
a catholyte compartment;
a NaSICON membrane that separates the anolyte compartment from the catholyte compartment;
an anolyte is housed within the anolyte compartment, wherein the anolyte comprises a solvent comprising an alcohol and a quantity of sodium levulinate, sodium valerate, sodium 5-hydroxy pentanoate, or sodium 5-alkoxy pentanoate, and wherein the only positive cation in the anolyte compartment is a sodium cation;
a catholyte is housed within the catholyte compartment; and
a voltage supplier configured to decarboxylate the sodium levulinate, the sodium valerate, the sodium 5-hydroxy pentanoate, or the sodium 5-alkoxy pentanoate, wherein the decarboxylation forms radicals that react to form a hydrocarbon fuel compound.
2. The electrolytic cell as claimed in claim 1 , wherein the sodium levulinate, sodium valerate, sodium 5-hydroxy pentanoate, or sodium 5-alkoxy pentanoate comprises sodium valerate, wherein decarboxylation of the sodium valerate produces radicals that react to form octane.
3. The electrolytic cell as claimed in claim 1 , wherein the sodium levulinate, sodium valerate, sodium 5-hydroxy pentanoate, or sodium 5-alkoxy pentanoate comprises sodium levulinate, wherein decarboxylation of the sodium levulinate produces radicals that react to form 2,7-octadione.
4. The electrolytic cell as claimed in claim 1 , wherein the sodium levulinate, sodium valerate, sodium 5-hydroxy pentanoate, or sodium 5-alkoxy pentanoate comprises sodium 5-hydroxy pentanoate, wherein decarboxylation of the sodium 5-hydroxy pentanoate produces radicals that react to form 1,8-hydroxy octane.
5. The electrolytic cell as claimed in claim 1 , wherein the sodium levulinate, sodium valerate, sodium 5-hydroxy pentanoate, or sodium 5-alkoxy pentanoate comprises sodium 5-alkoxy pentanoate, wherein decarboxylation of the sodium 5-alkoxy pentanoate produces radicals that react to form 1,8-dialkoxy octane.
