Abstract

A comparative analysis of the main characteristics of industrial catalysts and the innovative MAK-K catalyst in the dehydrogenation of cyclohexanol was performed. The main attention was paid to a comparison of MAK-K with H3-11 (BASF), which is currently the best catalyst in terms of activity and selectivity in the temperature range 220–270°C at a feedstock space velocity of 0.6–1.3 h^–1. Both catalysts are characterized by close dependences on these parameters; MAK-K is recommended for use at lower temperatures and higher space velocities. The results of the industrial tests of MAK-K (NIAP-KATALIZATOR) loaded in an amount of 1.4 m³ in reactor 2 of the cyclohexanol dehydrogenation shop of Shchekinoazot were also presented. The high level of activity and selectivity of MAK-K was confirmed over the period of operation (more than 2000 h), and this catalyst showed that it is highly competitive in respect of the tested samples, including foreign ones.

环己醇脱氢制环己酮中含铜催化剂的表征与测试

摘要

对工业催化剂和创新型MAK-K催化剂在环己醇脱氢中的主要特性进行了比较分析。主要关注的是将MAK-K与H3-11（BASF）进行比较，H3-11是目前活性和选择性最佳的催化剂，在220-270°C的温度范围内，原料空速为0.6-1.3 h ^–1。两种催化剂的特征均与这些参数密切相关。建议在较低的温度和较高的空速下使用MAK-K。负载量为1.4 m ³的MAK-K（NIAP-KATALIZATOR）的工业测试结果还介绍了Shchekinoazot的环己醇脱氢车间的反应器2中的反应。在整个操作过程中（超过2000小时），证实了MAK-K的高活性和选择性，该催化剂表明，它对包括外来样品在内的测试样品具有很高的竞争力。
