BUBBLE REACTOR OF CYCLOHEXANE OXIDATION Russian patent published in 2012 - IPC B01J10/00 

FIELD: process engineering.

SUBSTANCE: invention relates to reactors intended for liquid-phase bubble oxidation of cyclohexane by air oxygen at one of the main stages of caprolactam production in production of polyamide plastic materials. Proposed reactor comprises device to feed and distribute air with two plates connected with faces of through branch pipes that make branch pipe space, and holes to feed air from branch pipe space into reactor. Branch pipes or lower plate feature variable vertical section. Air feed holes are arranged on said section arranged on branch pipe lower parts or device lower plate. Axes of holes doe not cross walls of branch pipes.

EFFECT: higher safety.
