Abstract
A process for producing combustible product from an organic or biomass feedstock, the process comprising: mixing the feedstock with an alkaline material to give an alkaline aqueous mixture; heating the mixture by ohmic heating to a temperature in the range of about 280° C. to about 320° C. and reacting the mixture under subcritical conditions at the said temperature range and a pressure of about 6.6 to about 11.6 MPa (65 bar gauge to about 115 bar gauge); and removing at least some of the water to leave a combustible product, which may be used to form an aqueous slurry, suspension or emulsion and combusted in a suitable engine.

A process for producing a combustible product from an organic or biomass feedstock, the process comprising:
- mixing the feedstock with an alkaline material to give an alkaline aqueous mixture;
- heating the mixture by ohmic heating to a temperature in the range of about 280° C. to about 320° C. and reacting the mixture under subcritical conditions at the said temperature range and a pressure of about 6.6 to about 11.6 MPa (65 bar gauge to about 115 bar gauge);
- and
- removing at least some of the water to leave a combustible product.
A process for producing a liquid fuel from an organic or biomass feedstock, the process comprising:
- mixing the feedstock with an alkaline material to give an alkaline aqueous mixture;
- heating the mixture by ohmic heating to a temperature in the range of about 280° C. to about 320° C. and reacting the mixture under subcritical conditions at the said temperature range and a pressure of about 6.6 to about 11.6 MPa (65 bar gauge to about 115 bar gauge);
- removing at least some of the water to leave a combustible material;
- extracting a liquid hydrocarbon fraction from the combustible material, and combining the extracted hydrocarbon fraction with water to produce an emulsion suitable for use as a liquid fuel.
