Характеризация и испытания медьсодержащих катализаторов в процессе дегидрогенизации циклогексанола в циклогексанон

Main characteristics of currently used industrial catalysts and an innovative catalyst MAK-K for dehydrogenation of cyclohexanol were compared. Main attention was paid to comparison of the activity and selectivity of MAK-K and the best catalyst H3-11 (BASF) at 220–270 °C and feed flow rate of 0.6–1.3 h –1 . Similar behaviors were characteristic of both catalysts, the use of MAK-K being preferable at lower temperatures and higher feed flow rates. The MAK-K catalyst manufactured by LLC «NIAP-KATALIZATOR» was tested. The catalyst (1.4 m 3 ) was loaded to a reactor for dehydrogenation of cyclohexanol at Shchekinoazot Co. and employed for more than 2000 h to demonstrate its high activity and selectivity. The catalyst was competitive against all the samples under study.
