CATALYST, METHOD OF THEREOF PREPARATION AND PROCESS OF ENRICHING MIXTURES OF HYDROCARBON GASES WITH METHANE Russian patent published in 2015 - IPC B01J23/883 B01J23/86 B01J23/78 B01J21/04 C07C1/06 

FIELD: chemistry.

SUBSTANCE: described catalyst for enriching mixtures of hydrocarbon gases with methane, which as a base contains nickel in quantity 25-60 wt %, chromium counted per Cr₂O₃ in quantity 5-35%, aluminium oxide in quantity 5-70% and oxygen-containing compound of magnesium - the residual part. Claimed is method of said catalyst obtaining, which includes mixing oxygen-containing compounds of nickel, chromium, aluminium and magnesium with the following stages of drying, burning, tabletting or moulding. Also described is method of enrichment of mixture of hydrocarbon gases with methane by conversion in presence of oxygen-containing compounds on said catalyst.

EFFECT: increase of catalyst activity, stability in carrying out process of enrichment of mixture of hydrocarbon gases with methane.
