Manufacture of cyclohexane from benzene and a hydrogen source containing impurities

   
   

A process for producing cyclohexane by benzene hydrogenation using a hydrogen source that contains impurities, such as carbon monoxide and/or light hydrocarbons, wherein a supported catalyst reduces benzene to cyclohexane and carbon monoxide to methane and water. Alkenes, such as ethylene, are also reduced to their alkane counterparts. Under the disclosed operating conditions, the process proceeds without deactivation of the catalyst, and without the formation of a significant amount of cracking products, such as methylcyclopentane.

Um processo para produzir o cyclohexane pelo hydrogenation do benzene usando uma fonte do hidrogênio que contenha impurezas, tais como hidrocarbonetos do monóxido de carbono e/ou da luz, wherein um catalizador suportado reduz o benzene ao monóxido do cyclohexane e de carbono ao methane e à água. Os alkenes, tais como o etileno, são reduzidos também a suas contrapartes do alkane. Sob as circunstâncias operando-se divulgadas, o processo prosegue sem deactivation do catalizador, e sem a formação de uma quantidade significativa de produtos rachando, tais como o methylcyclopentane.
