Latest Patents

Fexer holds a patent for a method for the production of a carbon fiber precursor. This method involves extracting coal tar pitch at elevated temperatures and pressures using a mixture of a supercritical gas and an entraining agent. The process aims to obtain a solution free of quinoline-insoluble components. By lowering the pressure and/or raising the temperature, Fexer’s method recovers fractions that can be treated under specific conditions to produce isotropic pitch with a high mesophase content. This isotropic pitch can then be used to create high-quality carbon fibers.
