摘要
以加工加氢渣油的茂名石化3#重油催化裂化装置的工业数据为基础,针对加氢渣油的特点,提出了以渣油四组分作为划分原料集总基础的催化裂化七集总动力学模型。通过变尺度法(B-F-G-S)和龙格库塔法确定动力学参数,并通过工业实测数据验证,表明该模型具有良好的拟合性和外推性,较好地反映了加氢渣油催化裂化反应规律。
According to the commercial data of 3^# RFCCU processing hydrotreated residuum in Maoming petrochemical company and the character of hydrotreated residuum, the kinetic model with 7 lumps for hydrotreated residuum fluid catalytic cracking based on the four-component of residual was presented. Its reaction rate constants were determined by B-F-G-S and RungeKutta. The verification results by commercial data showed that the model was reliable, fitted well and reflected the reaction rules of hydrotreated residuum fluid catalytic cracking.
