FIELD: chemistry.
SUBSTANCE: invention relates to catalysts, used for obtaining element sulphur in Claus process. Claimed catalyst of obtaining element sulphur in Claus process represents mixture χ-, γ-Al2O3 and X-ray amorphous phase of aluminium oxide in the following ratio: χ-Al2O3 and X-ray amorphous phase 65-99.9 wt % and γ-Al2O3 0.1-35, wt %. Volume of mesopores with diameter from 3 to 10 nm in catalyst constitutes 0.12-0.35 cm3/g, and ratio of volume of mesopores with diameter 3-10 nm to volume of ultramacropores with diameter more than 1000 nm is less than or equals 5. Invention also relates to method of preparing said catalyst and method of carrying out Claus process with its application.
EFFECT: application of claimed catalyst makes it possible to increase efficiency of Claus process.
