METHOD OF ACTIVATING METHANE AROMATISATION MOLYBDENUM-ZEOLITE CATALYST

摘要

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.2 dwg, 5 ex
