Sustainable Conversion of Lignocellulose to High

2018/8/6The carbon net negative conversion of biochar, the byproduct of pyrolysis bio-oil production from biomass, to very high-purity (99.95%), highly crystalline flake graphite that is essentially indistinguishable from high-grade commercial Li-ion grade graphite, is reported. The flake size of the graphite is determined by the physical dimensions of the metal particles imbedded in the biochar

Effect of electrode material on electrical discharge

Abstract In this study the effect of electrode material was studied to avoid resulting residual stresses, the surface roughness and cracks resulted during Electrical Discharge Machining (EDM). Two types of EDM electrode materials were chosen, Dura graphite 11 and Poco graphite EDMC-3. Two grades of tool steels are chosen as test materials, DIN 1.2080 and DIN 1.2379. Different machining methods

Extrusion of graphite bodies

For finer graphite rolled sheets (e.g. EDM graphite) a slower drying step, for example 16 hours at 45 C. and 16 hours at 65 C., may be required to reduce the risk of blistering. [The finer graphite means finer porosity and this slows the escape of volatiles during the heat treatment].

Fabrication of Electrically Conductive, Fluid Impermeable Direct Methanol Fuel Cell (DMFC) Graphite

cost of production [1]. Graphite has been the standard material of choice for bipolar plates due to its high electrical conductivity and low mass. However, machining fine features such as flow channels and fuel manifolds on graphite plates is expensive since graphite
