| 英文摘要 | To investigate the influence of feedstock oil vaporization characteristics, a multi-phase Eulerian model coupling with the models of EMMS drag and mass transfer, oil droplet vaporization and twelve lumped reaction kinetics were used to simulate a million ton scale industrial FCC riser for predicting complex three-phase flow, reaction and coking behaviors. A coking model was proposed to predict the coking extent. The distribution of concentration and temperature of each phase, reaction component and coking extent were investigated under different droplet sizes of atomized feedstock oil and initial vaporization temperatures. The results show that the simulation can well predict the vaporization, reaction coking and fixed coking. The atomized droplet size and initial vaporization temperature affect the oil droplet vaporization rate and cracking reaction conversion rate through the interphase momentum transfer and vaporization speed. Appropriate droplet size (60 渭m) and initial vaporization temperature (654 K) can improve the yield of light oil, gasoline and liquefied petroleum gas and alleviate the degree of coking. 漏 2022 Chemical Industry Press.
