Abstract
The present disclosure describes compositions (bio-carbon materials) and methods of making compositions that comprise a binder (such as a phenolic binder which may comprise cardanol) and charcoal, preferably in a powder form. The composition may also include an accelerator/catalyst. The binder, charcoal powder, and accelerator may be mixed together, formed (pressurized, rolled, or extruded) and then cured. The resulting composition may be used as a metallurgical reducing agent, processed into anodes for use in the metallurgical industry, used in the construction industry for example as an ingredient in concrete, and as a fuel for cooking.
Claims14
A bio-carbon material having a compression strength of at least 5 MPa according to the ASTM C39/C39M method comprising:
- a charcoal;
- and
- one or more binders;
- wherein said one or more binders comprise a phenolic resin;
- wherein said phenolic resin is a polymer consisting of one or more phenols and an accelerator and/or catalyst;
- wherein said one or more phenols consists essentially of at least one of a cardol, a cardanol, or a combination of both thereof, each derived from cashew nut shell liquid;
- wherein said accelerator and/or catalyst is present in an amount of 0.1 to 15% by weight of the binder;
- and
- wherein said bio-carbon material is 50 to 90% by weight said charcoal.
