Effect of hydro-thermal treatment on properties of aluminosilicate catalysts in cracking of petroleum fractions

Abstract

1. 1. Hydrothermal treatment of gel during the synthesis of aluminosilicate catalysis increases catalytic activity in cracking of a kerosine-gas oil fraction by 3–7% of gasoline yeild. 2. 2. Aluminosilicate catalysts subjected to hydro-thermal tretment produce less coke and have a higher rate of oxidative recovery, compared with an industrial cracked catalyst containing zeolite. 3. 3. A catalyst obtained from a matrix subjected to hydro-thermal treatment and containing zeolite has a higher gasoline yield (46.4–51.0%) than AShNTs-3 spherical and zeolite-containing industrial aluminosilicate catalysts (39.0–45.4%).
