Plasmochemical hydrogenation of coal is a new process of direct production of acetylene and alkenes in the gaseous phase, in contrast to traditional processes of coal hydrogenation (liquefaction). Propanebutane mixture (50% C 3 H 8 +50% C 4 H 10), 200 t −1, is used as a hydrogenating agent instead of hydrogen, 2000 t −1.
