In the search for alternative energy sources, methane is of special interest as a fundamental component of natural gas. The cost of methane is rather low and it is an environmentally safe gas. Methane can be accumulated by microporous fibrous sorbents at supercritical pressure and temperature, i. e., high filling of micropores is achieved, and the adsorbed substance is in a special nanodispersed state. The use of an artificial porous fibrous substance obtained from carbon crystallites as the sorbent is proposed. Among a number of carbon fiber sorbents, preference is given to the porous fibrous material C200 obtained based on viscose fibers. Sorbent fibers were woven from individual threads each several micrometers in diameter. Unlike granular and powdered sorbents, it does not dust, has increased sorption kinetics due to high specific surface area, availability of functional groups, high absorption rate of various substances, and strength.
