Abstract: A Lithium energy storage device comprising a cathode, electrolyte, anode, and substrate. The materials contained in the anode and electrolyte region are electrochemically altered during initial formation and exposed to current cycles to create a lower impedance composite anode. The resulting composite anode bottom is a bi-layer comprising: i. a lithium metal layer and ii. a silicon-based interphase layer. The bi-layer acts as a barrier to inhibit Lithium ions from entering or leaving a Lithium saturated substrate, once the interphase surface is formed and the substrate is saturated with Lithium ions. This prevents cell failure from large volume changes/stresses during charge/discharge cycles and enables a significant decrease in cell impedance to enable better rechargeable cell performance.

Abstract: 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.
Abstract: A process and apparatus for gasification of biomass. Biogenic residue may be supplied to a heating zone to dry the biomass and allow the volatile constituents to escape to generate a pyrolysis gas. The pyrolysis gas is supplied to an oxidation zone and substoichiometrically oxidized to generate a crude gas. The carbonaceous residue generated in the heating zone and the crude gas is partially gasified in a gasification zone. The gasification forms activated carbon and a hot process gas. The activated carbon and the hot process gas are conjointly cooled. The adsorption process during the conjoined cooling has the result that tar from the hot process gas is absorbed on the activated carbon in the cooling zone. A pure gas which is substantially tar-free is obtained. The tar-enriched activated carbon may be at least partly burned for heating the heating zone and/or the gasification zone.
Abstract: A method and design of providing high temperature heat for an endothermic gasifier without combustion includes flowing a stream of a first hydrocarbon gas sequentially through an annular plenum and a cylindrical plenum while heating the gas using electrical resistance immersion heating elements. These heating elements may be heated by three phase electrical power, minimizing the number of electrical leads emerging from the top of the heating elements. This method and design reduces the risk of extremely hot syngas exiting the gasifier damaging downstream fittings.

Abstract: The present disclosure relates to a power production system that is adapted to achieve high efficiency power production with carbon capture when using a solid or liquid hydrocarbon or carbonaceous fuel. More particularly, the solid or liquid fuel first is partially oxidized in a partial oxidation reactor that is configured to provide an output stream that is enriched in methane content. The resulting partially oxidized stream can be cooled, filtered, additionally cooled, and then directed to a combustor of a power production system as the combustion fuel. The partially oxidized stream is combined with a compressed recycle CO2 stream and oxygen. The combustion stream is expanded across a turbine to produce power and passed through a recuperator heat exchanger. The recycle CO2 stream is compressed and passed through the recuperator heat exchanger and optionally the POX heat exchanger in a manner useful to provide increased efficiency to the combined systems.
