FIELD: chemistry.
SUBSTANCE: at the first step, the catalyst is heated in a hydrogen stream to temperature of 675…725°C and held at said temperature for 1…4 hours; at the second step, the catalyst is cooled to temperature not higher than 50°C and held at said temperature in a medium of an inert gas for 0.5…3 hours; at the third step, the catalyst is reheated in a hydrogen stream to temperature of the first step and held at said temperature for 0.5…2 hours.
EFFECT: catalyst activation enables to carry out the process of converting methane to aromatic hydrocarbons with high efficiency and achieve high output of aromatic hydrocarbons.
