Abstract

A method for producing an improved carbon foam electrically powered heating element from coal is disclosed. The method pulverizes coal into a fine coal powder; blends the fine coal powder with at least one additive to form a coal mixture; foams the coal mixture under an inert gas; pyroprocesses the coal mixture under an inert gas to form a carbon foam heating element having a resistivity in the range of about 0.01 to about 100 ohm-cm. Electrically conductive power connections resistively heat the carbon foam heating element. All steps are performed at atmospheric pressure. A device produced by these steps is also disclosed. Also disclosed is a method for producing and using a carbon foam composite tool from coal.

Abstract

An improved method to manufacture carbon foam at atmospheric pressure which eliminates the need to utilize an autoclave or similar device to pressurize the product during manufacture. Low viscosity liquid and offgas emerging during the heating steps escapes from the heating container through perforations. The method can further perform the step of adding at least one of a particulate pore stabilizer and an active polymer particulate to the starting material to form an admixture in the bed. A carbon foam, pore stabilized carbon foam, and polymer particulate modified carbon foam prepared at atmospheric pressure by these methods is also taught.
