In the work presented here, the feasibility study of the methanol production from pure CO₂ and H₂ has been conducted. This study focused on investigation of the previous kinetic models used for methanol synthesis by hydrogenation process at different processing conditions such as: pressure, temperature, catalyst loading and molar ratio of H₂ to CO₂ to select the best one. The results showed that, the combined rate expression containing both CO and CO₂ hydrogenation terms would result in the better yield. Besides, it was found that the reactor containing recycle mood ensures a higher efficiency up to 65% methanol yield at the range of (200–250 °C) and 50 bar. The kinetic model based on CO and CO₂ hydrogenation along with the proposed configuration showed the reasonable methanol yield in a practical methanol plant as much as 41%.

在这里介绍的工作中，进行了从纯 CO ₂和 H ₂生产甲醇的可行性研究。本研究的重点是研究以前用于通过加氢工艺合成甲醇的动力学模型，例如：压力、温度、催化剂负载和 H ₂与 CO _{2 的}摩尔比，以选择最佳模型。结果表明，包含CO和CO ₂加氢项的组合速率表达式将导致更好的产率。此外，发现包含循环模式的反应器可确保在 (200–250 °C) 和 50 bar 范围内实现高达 65% 的甲醇产率的更高效率。基于 CO 和 CO ₂的动力学模型 加氢以及建议的配置表明，在实际甲醇工厂中，合理的甲醇产率高达 41%。
