The reduction rate of A110-2 ammonia catalyst is investigated in a laboratory integal flow reactor during pressure 0.098-6.86MPa, temperature 360 -500℃ and space velocity 7-15 kh-1. Gas reactant is a mixture of hydrogen and nitrogen with more ratio 3:1 obtaned by catalytic ammonia decomposition. Global rate of reduction approached the intrinsic reaction rate, the temperature is an important factor to determine the reduction rate, and the activation energy of reaction is about 85 kJ/mol. Reduction rate will decrease with increasing water vapor in mixture. But this became obvious when extent of reduction is high. During reduction the reaction rate will increase with increasing pressure.

用积分反应器研究了A110—2氨合成催化剂的还原速率。还原用气体系由氨分解制成的氢氮混和气。实验条件为常压~6.86MPa,温度360~500℃,空速0.098~6.86MPah~(-1)和催化剂粒径1.0~3.0mm等。实验结果表明:还原过程属动力学控制,温度是决定还原速率的主要因素,还原反应的活化能约为85kJ/mol;氢氮气中水汽含量增高会降低还原速率,但是只在还原度高时才明显;压力高可使还原速率加快。

The gas-solid reaction aA(g)+bB(s)=cC(g)+dD(s) in a packed bed is theoretically investigated. For the packed bed with uniform particle size, the overall rate of representative-element volume is obtained from that of a single particle. Owing to the presence of inert gas and the compressibility of the gas mixture, the nonlinear convection-reaction-diffusion equations for the gas reactant and gas product, and the nonlinear flow equation for mixed gas are presented. Computation cases are given...

The gas-solid reaction aA(g)+bB(s)=cC(g)+dD(s) in a packed bed is theoretically investigated. For the packed bed with uniform particle size, the overall rate of representative-element volume is obtained from that of a single particle. Owing to the presence of inert gas and the compressibility of the gas mixture, the nonlinear convection-reaction-diffusion equations for the gas reactant and gas product, and the nonlinear flow equation for mixed gas are presented. Computation cases are given numerically by the finite volume method. The results show that the particle size and the reactor length affect considerably the performance of the reactor. Their effects on reaction and conversion can be represented by two dimensionless numbers, Peclet number and Thiele number. The reactor performance can be improved by changing the particle size and the reactor length.`

针对填充床中的气固反应aA(g)+bB(s)=cC(g)+dD(s),在微元体动力学研究的基础上,考虑到气体的压缩性和惰性组分的存在,从渗流力学观点出发,导出了反应气体与产物气体的非线性对流反应扩散方程和混合流体渗流方程,用有效容积法求方程的数值解,通过实例计算,分析了不同条件下的反应转化情况.结果表明,颗粒尺度和反应器长度对反应进程有明显影响,这些影响可以用Thiele数、Peclet数及它们的比值来衡量,适当选取颗粒尺度和反应器长度可以改善反应器性能.
