Hierarchical Auto-Ignition and Structure-Reactivity Trends of C2–C4 1-Alkenes

open access: yesEnergies, 2021
Ignition delay times of small alkenes are a valuable constraint for the refinement of the core kinetic mechanism of hydrocarbons used in representing combustion properties of real fuels. Moreover, the chemical reactivity comparison of those small alkenes

One Step Formation of Propene from Ethene or Ethanol through Metathesis on Nickel Ion-loaded Silica

open access: yesMolecules, 2011
Increased propene production is presently one of the most significant objectives in petroleum chemistry. Especially the one-step conversion of ethene to propene (ETP reaction, 3C2H4 ® 2C3H6) is the most desired process.
