在自制的５００ｍｌ浆态搅拌釜内采用模试鼓泡浆态反应器无载体沉淀Ｆｅ－Ｃｕ－Ｋ催化剂进行了ＦＴ合成动力学研究。在２５０～２８０℃，１．５ＭＰａ，１－２．５ｌ／ｇｃａｔ．ｈ和Ｈ２／ＣＯ＝１．０９（ｍｏｌ）范围内，排除传质效应的条件下，得到了本征动力学数据，实验结果用线性和非线性参数估计方法按照速率常数ｋ、活化能Ｅ和吸附平衡常数Ｋ均为正值，筛选了不同的动力学模型。由烯醇机理推导的动力学模型较好地关联了实验结果，其速率表达式为－ＲＨ２＋ＣＯ＝６．０×１０３ｅｘｐ（７１．０／ＲＴ）ＣＨ２１＋０．３１８ＣＨ２ｏ／Ｃｃｏ它关联实验数据的最大误差在±１１％范围内，活化能７１ｋＪ／ｍｏｌ，落在文献报导的６３～１０９ｋＪ／ｍｏｌ之间。
The kinetics of FT synthesis was investigated in a home-made 500 ml slurry stirred tank using a Fe-Cu-K catalyst supported on a bubble-stripped slurry reactor. At 250 ~ 280 ℃, 1.5MPa, 1-2.5l / gcat. h and H2 / CO = 1.09 (mol). The intrinsic kinetic data were obtained under the condition of eliminating the mass transfer effect. The experimental results were estimated by the linear and nonlinear parameter estimation methods according to the rate constant k, the activation energy E and The adsorption equilibrium constant K was positive, and different kinetic models were screened. The kinetic model deduced from the enol mechanism correlates well with the experimental results. The rate of expression of the kinetic model is -RH2 + CO = 6.0 × 103exp (71.0 / RT) CH21 + 0.318CH2o / Cco. The maximum error associated with the experimental data is in ± 11%, the activation energy is 71kJ / mol, which falls in the range of 63 ~ 109kJ / mol reported in the literature.
