SDD/ SLD series catalysts are suited for use in the following applications:

  1. conventional diesel fuels dewaxing to deep dewaxing (Artic grade production) in 1st and 2nd stage applications,
  2. in combination with high pressure hydrocracking or mild hydrocracking catalyst package,
  3. in mild hydrocracker bottoms pour point reduction for storage and transportation and
  4. to produce lubes of exceptional quality.


Aromatics hydrocarbons processing

Transalkylation, Ethylbenzene reforming type and Ethylbenzene dealkylation type.

Paraffin isomerization

Paraffin Isomerization catalysts are utilized to increase the octane number and reduce the benzene content of hydrocarbon streams used in gasoline blending. The reaction takes place over a fixed bed of catalyst under mild temperature and pressure.
