传统的CO净化技术会造成变换气H_2的损失,为此本文提出通过在CO_2吸附塔出口段加入水气变换催化剂用于合成气CO的深度净化。首先证明了复合系统净化CO的热力学可行性,之后探索不同运行工况对CO净化性能的影响,最后进行了十循环连续测试。结果表明在真实合成气工况下(400℃,2 MPa,5.17%CO,20.8%CO_2,51.8%H_2,20.7%H_2O,1.60%Ar)复合系统具有较好的CO净化性能,其吸附剂利用率τ_(10),τ_(50),τ_(200)依次为0.090~0.337.0.417~0.723,0.699~0.810。
The traditional CO purification technology will result in the loss of H 2 gas. Therefore, this paper proposes to use deepwater gas shift catalyst in the outlet of CO 2 adsorption tower for the deep purification of CO. First of all, the thermodynamic feasibility of purifying CO with composite system was proved. Then, the effect of different operating conditions on the purification performance of CO was explored. Finally, a ten-cycle continuous test was carried out. The results show that the composite system has better CO purification performance under the condition of real syngas (400 ℃, 2 MPa, 5.17% CO, 20.8% CO 2, 51.8% H 2, 20.7% H 2 O and 1.60% Ar) The rates τ_ (10), τ_ (50) and τ_ (200) are 0.090 ~ 0.337.0.417 ~ 0.723 and 0.699 ~ 0.810, respectively.
