The chemical term alkanes, or paraffins, refers to organic compounds that consist of single-bonded carbon and hydrogen atoms, such as methane, ethane, and propane, and several other hydrocarbons. Over the years, alkanes have ...
Olefins are simple compounds of hydrogen and carbon but represent the building blocks of chemistry, and are vital for the synthesis of materials from polymers and plastics to petrochemicals. However, olefin production requires ...
