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.

A method and system for continuous production of contaminant free and size specific biochar using downdraft gasification of variable quality feedstock. The system and process of the present invention includes the transfer of biochar from a gasifier after gasification to a temperature-controlled cooling screw conveyor, into a drum magnet for ferrous metal removal into multiple diverters to separate and remove ungasified materials and non-ferrous metal contaminants, then transferred into a granulator for grinding and screening the biochar to a pre-selected size. By directly attaching a novel and continuous product treatment process to the biochar stream as it exits the gasifier, the particle size, moisture content, carbon content and yield of a contaminant free biochar product can be narrowly controlled and improved to meet strict product quality specifications required by specialty applications.

A downdraft gasifier and method of gasification with high yield biochar that utilizes a plurality of high throughput, vertically positioned tubes to create a pyrolysis zone, an oxidation zone beneath the pyrolysis zone and a reduction zone beneath the oxidation zone. A rotating and vertically adjustable rotating grate is located beneath the reduction zone of the gasifier. In addition, a drying zone is located above the pyrolysis zone so the heat of the gasifier can be used to dry feedstock before it enters the gasifier. By optimizing the grate height and rpm, feedstock retention time in the drying zone, the drying zone temperature and feedstock moisture content, the result is gasification of biomass with a high yield and continuous biochar production.
