History of Research, Development and Implementation of Dicyclopentadiene Production in Litvínov

The steam cracker unit at ORLEN Unipetrol is a significant European producer of monomers. Due to heavy feedstocks, the can produce (besides ethylene, propylene and benzene) very valuable hydrocarbons such as dicyclopentadiene. staff (formerly Chemopetrol) has been investigating possibility producing dicyclopentadiene for almost 40 years. As result many years research activities several generations researchers, technology production various quality grades developed realized in plant Litvínov. paper summarizes history on from moment construction Litvínov 1980 when was put into operation 2022. primarily an appreciation all researchers who have involved development this product over it be inspiration further C5 chemistry.
