FIELD: process engineering.

SUBSTANCE: invention relates to composition intended for producing catalyst carrier, to method of producing said carrier, to catalyst and method of its production, and to method of ethylene oxidation in its presence. Proposed composition comprises the mix of at least one alpha aluminium oxide with mean particle size of about 5 mcm or larger in amount of about 20 wt % to about 40 wt % of total content of aluminium oxide in this composition; at least, one hydrated precursor of alpha aluminium oxide in amount of about 60 wt % to about 80 wt % total content of aluminium oxide in this composition; binder and foaming agent. Invention covers also method of producing catalyst carrier comprising producing above described composition and heating it to convert into porous melted structure, method of producing catalyst comprising deposition of catalytically efficient amount of silver on said catalyst carrier, and catalyst produced as described above. It covers also the method of oxidising ethylene to ethylene oxide comprising gas-phase oxidation of ethylene by molecular oxygen in tubular reactor with stationary layer in the presence of produced catalyst.

EFFECT: higher strength and optimum porosity, high selectivity in ethylene oxidation to ethylene oxide at preset ethylene conversion.
