FIELD: petroleum chemistry.
SUBSTANCE: invention relates to petrochemistry. Nanocrystalline catalyst for cracking propane in order to obtain olefins is a nanocrystalline form of aerogel of aluminium oxide. Method of producing nanocrystalline catalyst for cracking propane in order to obtain olefins involves amalgam oxidation with further crystallisation of nanofibrous aluminium oxide in a stream of hydrogen at temperature starting from 600 K and each hour of raising temperature by 50° and reaching temperature of 1,200 K, which is maintained for 10 hours or in a hydrogen atmosphere for 5 hours.
EFFECT: use of catalyst provides high yield of olefins.
