Abstract: Herein disclosed are apparatus and associated methods related to producing an enhanced surface area biochar product with a desired activation level based on receiving biochar into a processing vessel configured with multiple independently temperature-controlled chambers and counter-flow steam injection, controlling activation levels of the biochar by moving the biochar through the processing vessel and adjusting the temperature of the biochar by injecting steam into at least one temperature-controlled chamber of the processing vessel, recovering volatiles driven off through dehydration using a thermal oxidizer, cooling the biochar to a desired discharge temperature using steam and retention time, and discharging the activated biochar product. The processing vessel may be a calciner, a rotary calciner, or a kiln. Biochar may be heated or cooled to a desired thermochemical processing temperature depending on the temperature of the received biochar. Counter-flow saturated steam may sweep volatile gases to a thermal oxidizer using a vacuum system.

Abstract: An apparatus and methods to eliminate PFAS from wastewater biosolids through fluidized bed gasification. The gasifier decomposes the PFAS in the biosolids at temperatures of 900-1800° F. Synthesis gas (syngas) exits the gasifier which is coupled to a thermal oxidizer and is combusted at temperatures of 1600-2600° F. This decomposes PFAS in the syngas and creates flue gas. Heat can be recovered from the flue gas by cooling the flue gas to temperatures of 400-1200° F. in a heat exchanger that is coupled with the thermal oxidizer. Cooled flue gas is mixed with hydrated lime, enhancing PFAS decomposition, with the spent lime filtered from the cooled flue gas using a filter system that may incorporate catalyst impregnated filter elements. The apparatus and methods thereby eliminate PFAS from wastewater biosolids and control emissions in the resulting flue gas.

Abstract: Apparatus and associated methods relate to cooling hot biochar based on applying cool gas directly to the hot biochar. The gas may be steam comprising water vapor. Biochar may be cooled in a cooling chamber by cool steam injected into a steam loop configured to cool the steam. The biochar cooled with steam may be dried in a drying chamber by dry gas injected from a gas loop. The gas may be hydrocarbon gas. Biochar may be heated in a processing chamber. Heated biochar may be cooled in a cooling chamber by cool hydrocarbon gas injected to the cooling chamber. Biochar in the processing chamber may be heated with heat recovered from cooling. Filtered byproducts and tail gas may be recovered from the cooling chamber. Tail gas may be recycled. Various direct biochar cooling implementations may produce biochar having enhanced carbon content, increased surface area, and a hydrogen stream byproduct.
