     Influence of compact density,amount of diluent and Nitrogen pressure on the synthesis processing and synthesis conversion rate was studied. Results showed that the TiN fabricated by SHS consisted of TiN and Ti solid solution,purity TiN can be achieved by control of synthesis processing parameters. The major parameters that contrlled the conversion rate include the contact area and transportation velocity of Nitrogen gas toward reaction zone.
     采用自蔓延高温合成法(SHS)制备了TiN陶瓷粉末,研究了压坯密度,稀降剂掺加及氮气分压对合成过程和合成转化率的影响.结果表明:采用SHS法制备的TiN是由TiN及少量Ti的固溶体构成的,通过改变工艺参数,可以得到高纯度的TiN.影响TiN转化率的关键因素是Ti粉与氮气的有效接触面积和氮气向反应区的转输速度.

The macro-kinetics of the Fischer-Tropsch synthesis reaction are studied in an internally recycled reactor (CSTR) over a commercial, precipitated Fe/Mn/K catalyst. Kinetic data are obtained for 1.47 ̄4.04H2/CO feed gas over a temperature range of 265 ̄315℃, a pressure range of 1.03 ̄2. 60MPa, and a space velocity range of 331 ̄811h(-1). The kinetic model which fitted the experimental data well is the same as that of the intrinsic kinetics, i. e., -RH2(+∞)=aP(CO)PH2/P(CO)+bPH(H2O),where a is the kinetic contant for...

The macro-kinetics of the Fischer-Tropsch synthesis reaction are studied in an internally recycled reactor (CSTR) over a commercial, precipitated Fe/Mn/K catalyst. Kinetic data are obtained for 1.47 ̄4.04H2/CO feed gas over a temperature range of 265 ̄315℃, a pressure range of 1.03 ̄2. 60MPa, and a space velocity range of 331 ̄811h(-1). The kinetic model which fitted the experimental data well is the same as that of the intrinsic kinetics, i. e., -RH2(+∞)=aP(CO)PH2/P(CO)+bPH(H2O),where a is the kinetic contant for the rate-determining step and b is a function of temperature only. This model may be derived by assumpting that the rate-determining step is the hydrogenation of adsorbed CO, according to the enol mechanism. It is found that the H2/CO usage ratio is probably independent of synthesis conversion and total pressure, and the catalyst shows high water-gas-shift activity.

在内循环无梯度反应器中研究了工业颗粒沉淀Fe/Mn/K催化剂的F-T合成宏观反应动力学。其温度变化范围为265~315℃、压力1.03~2.60MPa、原料气H2/CO比1.47~4.04、空速331~811h(-1)。在此研究范围内观察到水对反应的抑制作用,但无CO2的抑制作用。宏观动力学模型较好地拟合了实验数据且具有与本征动力学模型相同的形式。合成气利用比是原料气氢碳比和温度的函数,而与转化率及总压无关。
