FIELD: process engineering.
SUBSTANCE: invention relates to petrochemical and chemical industries, particularly, to production of methane conversion catalyst, method of its production and method of converting methane into aromatic hydrocarbons in nonoxidising conditions. Zeolite catalyst comprises molybdenum in amount of not over 4.0 % by wt as modifying element, carbamide as structure-forming additive, and nano-sized silver powder as second modifying element, said silver powder produced by conductor electrical blasting, at concentration varying from 0.1 to 2.0 wt %. Proposed method allows producing catalyst by dry mixing of zeolite modified by molybdenum with molybdenum content not exceeding 4.0 wt % with second promoting agent, i.e. nano-sized silver powder with its content in produced catalyst varying from 0.1 to 2.0 wt %. Method of methane nonoxidising conversion is performed in the presence of above described catalyst.
EFFECT: higher degree of methane conversion and yield of aromatic hydrocarbons along with catalyst longer life.
