Specialized Activated Carbon Derived From Pretreated Biomass
Provided are methods, systems, and compositions for producing activated carbon from lignin residues produced from cellulosic or lignocellulosic biomass after hydrolysis of saccharides. The activated carbon is low in ash and sulfur, high in oxygen content and iodine number.
POROUS CARBON ELECTRODES FOR ENERGY STORAGE APPLICATIONS
The present patent application discloses a method of producing nano-porous carbon, comprising mixing furfuryl alcohol or its fast-polymerizing derivatives with an aluminum-based solid polymerization catalyst, heating the mixture until a solid catalyst-carbon matrix forms, heating again under inert atmosphere and etching the powder to remove the matrix to produce a network of pores in the nano-porous carbon. The application further provides a method for making of fabricating tailor-made nano-porous carbon electrodes.
Highly mesoporous activated carbon
Highly mesoporous activated carbon products are disclosed with mesoporosities characterized by mesopore volumes of 0.7 to 1.0 cubic centimeters per gram or greater. Also disclosed are activated carbon products characterized by a Molasses Number of about 500 to 1000 or greater. Also disclosed are activated carbon products characterized by a Tannin Value of about 100 to 35 or less. The activated carbon products may be further characterized by total pore volumes of at least 0.85 cubic centimeters per gram and BET surface areas of at least about 800 square meters per gram. The activated carbon product may be derived from a renewable feedstock.

VERTICALLY ORIENTED PLASMA REACTOR
A vertically oriented plasma reactor is provided. In another aspect, a plasma reactor includes a vertically elongated vacuum chamber, a wall internally projecting within a middle section of the housing, magnets, electrodes and a radio frequency source. A further aspect employs a workpiece-entry port and an opposite workpiece material-exit port, with one located adjacent a top end and the other adjacent a bottom end of a vertically elongated reactor housing or vacuum chamber. Yet another aspect employs a moving or falling-bed plasma reactor for use in activating biochar material.

Carbon Monoliths and a Process for Producing Same
A carbon monolith and a process of producing same, the process comprising the steps of: (i) mixing a carbonaceous precursor material with an alkali salt to form a first mixture; (ii) extruding the first mixture produced in step (i) into the shape of a monolith; and (iii) carbonizing the monolith produced in step (ii).
Yolk-shell-structured material, anode material, anode, and battery
A yolk-shell-structured material (16, 59, 59a, 74) is disclosed as including a plurality of silicon nano-particles (12, 54, 54a, 62) and a cavity (16, 60, 80, 84) enclosed by a micron-sized shell (18, 72) made of carbon nano-particles (14, 56, 58). The yolk-shell structured material is formed as a micron-sized shell (18) made of carbon nano-particles (14) by (a) providing a micron-sized cornstarch core (10), (b) forming a layer of nano silicon-particle (12) on the cornstarch core (10), (c) forming a micron-sized shell (18) of carbon nano-particles (14) on the layer of nano silicon-particle (12), and (d) removing the cornstarch core (10) by heating.
