Abstract：To study the effect of the height of the draft tube on the loop reactor flow characteristics, the model of a gas-solid circulating fluidized bed in a loop reactor was established based on Euler - Euler method using Energy Minimization Multiscale(EMMS) drag force model with the particle kinetic theory. The appropriate model parameters were determined by comparing the experimental data. The height of draft tubes was studied and optimized using the established model and the effects of changes of the height of the draft tube on the average bed density, mass flow rate and other factors were investigated. Results showed that the gas-solid airlift loop reactor(GSALR) with a 1.4 m high draft tube performed better and an average mass flow rate was higher than that of the original device with a 1.2 m draft tube by 36.17%.
