摘要：本文对 C30 1及 C30 2两种不同催化剂条件下机械搅拌反应器内液相法甲醇合成过程进行了模拟。模拟中考虑了气液之间的传质过程及催化剂气固相本征反应动力学。主要模拟条件 :温度 483K～ 5 2 8K,压力 2 .0 MPa～ 6 .0 MPa,原料气中 CO浓度 0 .0 6～ 0 .45。模拟结果表明 :在 C30 1与 C30 2催化剂条件下 ,甲醇生成总体速率的模拟计算值与实测值相吻合 ,平均偏差分别为 7.98%和 11.92 %。可以认为 。
A model, including both mass transfer of gas-liquid and gas-phase intrinsic kinetics, of a mechanically agitated slurry reactor was established for the three-phase methanol synthesis process at the conditions of the temperature ranging from 483K to 528K and the pressure ranging from 2.0MPa to 6.0MPa and CO content raging from of the global rates 0.06 to 0.45 with two different kinds of catalyst. For C301 and C302 catalyst, the simulated results were in good agreement with the experimental results, and average absolute relative deviations between the calculated values and the experimental values of methanol yield were 7.98% and 11.92%, respectively. It can be concluded that the intrinsic kinetic model developed in gas-phase methanol synthesis is applicable and reliable for the engineering design and analysis of liquid-phase methanol synthesis processes.
