The plug flow reactor (PFR) setup is aimed at performing steam cracking experiments (feed ranges from ethane to light naphtha) for conversion into light olefins. Gaseous hydrocarbons are fed directly to reactor, operated around 750°C and 1-2 bar pressure. The central part of the reactor holds a coupon, which is fitted to a kanthal wire and centered in the crystal reactor, with the heating elements mounted in a circle configuration to achieve the desired reactor temperature in a uniform way. Products from this setup are analyzed using two gas chromatography (GC) devices. Hydrocarbons with carbon number less than 4, are identified and quantified by refinery gas analyzer, whereas hydrocarbons with higher carbon number are identified and quantified via GC with FID (flame ionization detector).
