    摘要: Algae-derived synthetic coal and filtrates. The invention described herein provides an algae-derived synthetic coal product and filtrates and process for preparing the same using an improved hydrothermal carbonization process. The synthetic coal product is similar to natural bituminous coal in terms of percent carbon content and energy equivalency while at the same time containing relatively low levels of sulfur and contaminant heavy metals. Unlike natural coal and other fossil fuels, because the carbon of the biomass is formed through photosynthesis, carbon dioxide formed during combustion is a “carbon neutral” event with little or no “new” carbon dioxide being added to the earth's atmosphere. The algae-derived filtrates contain useful constituents.

    摘要: The invention herein describe a novel process for producing a novel synthetic coal product from fermentation residues, such as, the waste materials from fermentation based ethanol production. The fermentation residue is subject to a hydrothermal carbonization process in an aqueous solution at a temperature and at a pressure sufficient to form a synthetic coal solid and a liquid component. This process does not require drying of the fermentation residue which provides for a more energy efficient method of processing thereof. The synthetic coal solid has a high heat content combustive material. The liquid component has nutrient value so that it can be recycled thereby permitting the sustainable recycling of such nutrients and the water in which those nutrients are dissolved.
