Aromatics hydrocarbons processing

Transalkylation, Ethylbenzene reforming type and Ethylbenzene dealkylation type.

Catalytic dewaxing

Used to improve cold flow properties of diesel fuels and lube oils by selective hydroisomerization/ hydrocracking of normal and slightly branched paraffins.

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.



Zeolites are widely used as catalysts in the refining of crude oil into finished petroleum products.


Zeolites are increasingly finding use in the production of petrochemicals, often replacing environmentally unfriendly catalysts.


Zeolites are being studied extensively as heterogeneous catalysts that can be recovered and recycled with greater ease and lower expense, leading to less waste and fewer byproducts.
