METHOD FOR FLUID CATALYTIC CRACKING OF HEAVY OIL

Title:

METHOD FOR FLUID CATALYTIC CRACKING OF HEAVY OIL

Document Type and Number:

WIPO Patent Application WO/2015/182329

Kind Code:

A1

Abstract:

A method for the fluid catalytic cracking of a heavy oil, the method being for obtaining light olefins such as propylene and butene in high yield by subjecting a heavy oil to fluid catalytic cracking at a high temperature for a short contact time, characterized in that a catalyst containing 12-24 mass% shape-selective zeolite is brought into contact with the heavy oil under such conditions that the reaction zone outlet temperature is 580-630°C, the catalyst/oil ratio is 15-40 by weight, and the hydrocarbon residence time in the reaction zone is 0.1-1.0 second, thereby obtaining a product of cracking which has a value of secondary cracking activity ((C2 olefin concentration)/(C4 olefin concentration)) in the range of 0.30-0.55.
