Reactive Distillation Technology Introduction
Structured catalyst supports are used and applied in gas-liquid reaction systems. These advanced catalyst particles are firmly fixed between two layers of metal wire mesh, forming a unique “sandwich” structure. Each sheet is corrugated, creating flow channels with specific angles and hydraulic diameters. The sandwich layers and flow channels are assembled in opposite directions, resulting in an open cross-flow structural pattern.

Why Choose DODGEN Reactive Distillation
Esterification: Acetate esters (e.g., methyl acetate, ethyl acetate, butyl acetate), acrylate esters (e.g., methyl acrylate, ethyl acrylate, butyl acrylate), phthalate esters, malonate esters, and other diacid esters; FAME (fatty acid methyl esters, biodiesel).
Etherification: Oxygenates (e.g., MTBE, ETBE, TAME); glycol ethers (e.g., ethylene glycol ethyl ether, diethylene glycol butyl ether).
Hydrogenation: Selective hydrogenation of butadiene; hydrogenation of nitroaromatics; hydrogenation of fatty acids.
Process Water Purification: Removal of organic compounds (e.g., formaldehyde) from process water; removal of nitrates from wastewater.
