METHOD FOR CATALYTIC PYROLYSIS OF HYDROCARBON MIXTURE C-C INTO LOWER OLEFINS C-C Russian patent published in 2016 - IPC C10G11/02 C10G11/04 B01J23/26 C07C4/06 C07C11/02

Abstract RU 2601864 C1

FIELD: oil and gas industry.

SUBSTANCE: invention relates to petrochemistry, concerns a method for catalytic pyrolysis of a hydrocarbon mixture C₁-C₄ into lower olefins C₂-C₄, which can be used in processes of polymerisation, alkylation and esterification. Method for catalytic pyrolysis of hydrocarbon mixture C₁-C₄ into lower olefins C₂-C₄ is carried out in a flow tubular reactor at temperature 710-830 °C. Novelty is that method is carried out in presence of pyrolytic chromium formed in form of a film coating on surface of aluminosilicate ash microspheres, at pressure close to atmospheric pressure, rate of transmission of gas mixture of 25-100 ml/min, contact time 0.67-17.0 s, values of heterogeneous factor 6.7-5.6·10⁵ cm^-1.

EFFECT: technical result from use of invention is simplification of method due to easier forming of film coating on a carrier, higher safety with high total output of olefins, such as ethylene and propylene, and reduced coke formation.
