摘要
托普索MK-121型甲醇合成催化剂为铜系催化剂,开车前呈氧化态,无活性,必须首先还原成金属铜,才能在反应中起到催化作用。介绍了60万t/a甲醇合成装置工艺流程、MK-121型甲醇合成催化剂的组成,重点讲述了升温及还原过程,通过对比实际化学出水量与理论出水量,观察合成塔进出口氢气浓度与温度变化、过程中存在的测量误差以及水量损失等因素,得出催化剂已被完全还原,为后期装置长、满、优、高效生产奠定了基础。
Topsoe MK-121 type methanol synthesis catalyst is a kind of copper based catalyst. Before driving, it is the oxidation state and no activity, Eso it must be firstly reduced to metallic copper to play the role of catalysis in reaction. The process flow of 60 million tons methanol synthesis device and the composition of MK-121 type methanol synthesis catalyst were introduced, and the temperature rising and the reduction process were mainly described. By comparing the actual chemical effluent volume and the theoretical output, observing the hydrogen concentration and temperature change in the inlet and outlet of the synthetic tower, the existing measurement error and the water quantity and other factors loss in the process, it is concluded that the catalyst has been fully restored, so the later device can realize the long, full, excellent and efficient production.
