Aromatics Production

Benzene Hydrogenation to Cyclohexane (CDHydro®)

The patented CDHydro® process achieves selective hydrogenation of diolefins to amylenes in a catalytic distillation column. The process uses commercially available catalyst in proprietary catalytic distillation structures. 

The unique catalytic distillation column combines reaction and fractionation in a single unit operation. This constant pressure boiling system assures precise temperature control in the catalyst zone. Low reaction temperature and isothermal operation enhance selectivity and minimize yield losses to paraffins.
