FIELD: chemical industry.

SUBSTANCE: method for producing hydrogen by thermal cracking of methane with simultaneous synthesis of carbon nanotubes (CNTs) is proposed. During the cracking process, methane and hydrogen are supplied in a molar proportion of 1.15:1 with a total gas consumption not exceeding 26 moles per 100 g of catalyst. When carrying out the process, a catalyst containing 95-99 mol.% magnesium oxide is used, the rest is the metals Co and Mo in a molar ratio of 4:1. The exhaust gases are separated into methane and hydrogen and accumulated in appropriate cylinders for subsequent use. A plant for methane cracking and synthesis of carbon nanotubes is also proposed.

EFFECT: group of inventions allows to ensure a continuous cracking process producing high quality CNTs without formation of carbon dioxide.
