Product Overview
Pitch-based activated carbon fiber is a novel, highly efficient, multifunctional adsorption material made from pitch-based carbon fiber. The material is activated through a special process, resulting in a fiber structure with significantly enhanced adsorption capabilities. Compared to traditional granular activated carbon, pitch-based activated carbon fiber offers a finer diameter, larger specific surface area, more developed microporous structure, and uniform pore distribution. This material exhibits high adsorption capacity, fast adsorption and desorption speeds, and excellent regeneration performance. It can be used stably in acidic and alkaline environments, with outstanding high-temperature resistance, conductivity, and chemical stability.
