Three-Phase Gas-Liquid-Solid-Catalyzed Reactions

2 Three-Phase (Gas-Liquid-Solid-Catalyzed) Reactions 

TABLE 8.1 Industrially Important Reactions Carried Out in Venturi Loop Reactors with Relative Merits Over Stirred Reactors 

Hydrogenation of -nitro benzoic acid to -amino benzoic acid 

Enhanced yield of cyclohexylamine Yield increased from 81% in conventional stirred reactor to 93.5% (please refer to Section 8.13, Worked Examples for Design of Venturi Loop Reactor Hydrogenation of Aniline to Cyclohexylamine) Relatively short time of 4h at a lower pressure of 2.5 MPa. Unreacted sugar as low as 0.03% Catalyst consumption reduced by 80% as compared to conventional stirred reactor 

Batch time simultaneously reduced by 100% without any change in product quality.
