The critical level content of CH3-groups and hydrogen atoms ratio in the aromatic and interfacial fragments and CH3-groups (aliphatic fragments) is precondition for intense methane formation. This ratio was determined as 4:1. In this case proficient process in the reaction zone is assured. The process is the same as in nano-reactor.
