Tube in Tube

Apeiron’s patent pending tube-in-tube reactor design was successfully applied in homo- and heterogeneous olefin metathesis reactions under continuous flow mode. Our reactor efficiently removed ethylene under vacuum conditions thereby significantly improving the outcome of metathesis reactions.


  • Efficient and continuous removal of ethylene
  • No scale-up effects
  • High mixing rates
  • Efficient temperature control
  • Marginal concentration gradients
