COMPOSITE NANOCRYSTALLINE CATALYST FOR PROPANE CRACKING TO OBTAIN OLEFINS AND METHOD FOR ITS PRODUCTION Russian patent published in 2016 - IPC B01J21/04 B01J21/06 B82B3/00 C01F7/42 

FIELD: petroleum chemistry.

SUBSTANCE: invention relates to petrochemistry. Composite nanocrystalline catalyst for propane cracking to obtain olefins contains nanocrystalline aluminium oxide, modified with titanium oxide or silicon oxide with mass fraction of latter from 0.35 to 5 %. Method of producing composite nanocrystalline catalyst involves obtaining nanofibrous aerogel of aluminium oxide by oxidation of aluminium plate by humid air at room temperature and impregnation of produced carrier with solutions of titanium isopropoxide (IV) or triethoxychlorosilane at increasing temperature from 373 K to 473 K, with further crystallization in stream of hydrogen at increasing temperature from 600 K to 1,200 K or in hydrogen atmosphere at temperature of 1,200 K.

EFFECT: use of catalyst provides high yield of olefins.
