The principle,factors and the role of various factors of coke formation process of disengager were expounded.

The rigidity of coke was chiefly affected by the ways of oil droplets and catalyst particles accumulating and/or depositing together during coke formation.

In ethylene furnaces,coke formation reduces product yields,increases energy consumption and shortens runlength.
