摘要

Abstract

There are great interests to capture the CO

to control the greenhouse gas emission. Amine absorption of CO

is being taken as an effective way to capture CO

in industry. However

the amine absorption of CO

is cost-ineffective due to great energy consumption and solution consumption. In order to reduce the capture cost

catalyst fluidization is proposed here to intensify the mass transfer and heat transfer. Catalyst fluidization with field synergy and DFT model is developed by incorporating the effects of catalyst reaction kinetics

drag force and multi-field into the mass transfer

heat transfer

fluid flow and catalyst collision. Experiments with an improved distributor are performed well to validate the model. The reaction kinetics is determined by the DFT simulation and experiment. The mass transfer coefficient in the fluidized reactor is identified as 17% higher than the conventional packed reactor. With the field synergy of catalyst fluidization

the energy consumption for CO

desorption is reduced by 9%. Stepwise operation and inclination reactor are used to improve catalyst fluidization process.
