A key catalyst for the partial hydrogenation of benzene to produce cyclohexene, which can also be applied to the partial hydrogenation of other aromatics to produce cycloolefins.
Product Characteristics
Benzene Partial Hydrogenation Catalyst is a precious metal catalyst with ruthenium as the main component. The catalyst has suitable hydrogenation properties and in the presence of the additives zirconium oxide and zinc sulphate, high cyclohexene yields can be obtained.
Item | Unit | value |
Specific activity | g (benzene)/g(catalyst)· h-1 | ≥70.0 |
Conversion rate | % | ≥50.0 |
Selectivity | % | ≥80.0 |
Process conditions
The Benzene Partial Hydrogenation Catalyst is used in the partial hydrogenation of benzene, which is currently the dominant process for the production of cyclohexanone and hence adipic acid and caprolactam. The process schematic is shown below,
Technological Advantages
(1) Catalyst performance excellent
In laboratory small-scale evaluations, the guaranteed conversion rate is 60% and selectivity is 80% (under standard evaluation operating conditions);
In industrial applications, under conditions where stable operation is achievable at a conversion rate of 45% and selectivity of 80% or higher, optimization of operating conditions is expected to achieve a conversion rate of 50% and selectivity of 80% or higher.
(2) Low catalyst consumption
The catalyst consumption for producing one ton of cyclohexanol should not exceed 3g;
(3) More stable performance
The catalyst exhibits rapid and stable start-up and shut-down, with a long turnaround period.
