Measure time-at-temperature data in the catalyst system on the catalyst ageing bench following the SBC.

Measure time-at-temperature data in the catalyst system on the catalyst ageing bench following the SBC.

This application discloses a process for catalytically dewaxing a feedstock whereby the aging of the dewaxing catalyst is miminized.

By altering the catalyst, ever higher operation temperatures are required thus having an adverse effect on the quality of the product.

1,1 This value adjusts the catalyst ageing time to account for deterioration from sources other than thermal ageing of the catalyst.

The invention relates to a method for determining the light-off temperature of a catalytic converter on a motor vehicle.

Said method makes it possible to determine the aging condition of the catalytic converter.

Measure time-at-temperature data in the catalyst system on the catalyst ageing bench following the SBC.

Surprisingly it has been shown that the aging of the oxidation catalyst (2) can be delayed when the same is divided into at least two separate catalysts and the separation between them is 2 to 30mm.

The hydrotreating catalyst helps prevent aging of the dewaxing catalyst and maintains lubricant oil product yield at a target pour point over a wide temperature range.

Measure time-at-temperature data in the catalyst system on the catalyst ageing bench following the SBC.

The modules include a test conditions module, a testing module, a monitoring module, and a catalyst aging module.
