Organic chemists aim to separate alkenes such as ethylene and propene from alkynes before converting them into polymers. The technique has several drawbacks including hydrogenation of alkynes to produce unwanted alkanes, ...
ZSM-5 zeolite plays a vital role in petroleum cracking and refining of petrochemical products due to its microporous structure (0.51-0.56 nm) and tunable solid acid characteristics. Since zeolite micropores limit the mass ...
