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.

Methods and systems for producing an enhanced surface area biochar product

Exemplary apparatus or method implementations for a universal feeder system configured with a transfer screw feeder within a multi-section clamshell pipe permitting access to the feed screw and pipe interior for inspection, maintenance and/or cleaning during production, without disassembly or screw removal. The clamshell screw feeder pipe provides access to the screw by opening or removing the multi-section top portion of the clamshell pipe. The top pipe section is bolted and or hinges to the bottom portion of the clamshell pipe. The number of segmented multiple clamshell top sections depends on the length of the screw. One or more clamshell top sections may be configured with an inspection port. The universal feeder system configured with a transfer screw feeder within a multi-section clamshell pipe transfers feedstock feed from one or more feed vessels to one or more reactor vessel.

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&#xb0; F. Synthesis gas (syngas) exits the gasifier which is coupled to a thermal oxidizer and is combusted at temperatures of 1600-2600&#xb0; 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&#xb0; 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.

Elimination of poly- and perfluoro alkyl substances (PFAS) in a wastewater biosolids gasification process using a thermal oxidizer and hydrated lime injection

A universal feeder system that combines with a fluidized bed gasification reactor for the treatment of multiple diverse feedstocks including sewage sludge, municipal solid waste, wood waste, refuse derived fuels, automotive shredder residue and non-recyclable plastics. The invention thereby also illustrates a method of gasification for multiple and diverse feedstocks using a universal feeder system. The feeder system comprises one or more feed vessels and at least one live bottom dual screw feeder. The feed vessel is rectangular shaped having three vertical sides and an angled side of no less than 60 degrees from the horizontal to facilitate proper flow of feedstock material that have different and/or variable flow properties. The feedstocks are transferred through an open bottom chute to a live bottom dual screw feeder and through another open bottom chute to a transfer screw feeder that conveys feedstock to the fuel feed inlets of a gasifier.

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.
