Ethene homologation reaction to give propene (3C2H4 → 2C3H6) was examined on reduced molybdena silica (MoO3/SiO2) catalyst at initial ethene pressure around 14.66 kPa (110 mmHg) and a temperature of 30 °C. In the very first stage of the ethene homologation reaction, induction period was observed as well as previous results reported in the references. During the induction period, ethene dimerization providing 1-butene was preferentially occurred. In addition, it was indicated that isomerization… Expand

One Step Formation of Propene from Ethene or Ethanol through Metathesis on Nickel Ion-loaded Silica
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 theExpand
Reactive intermediates for the ethene homologation reaction on molybdena–silica catalysts
Ethene has been selectively homologated to propene (3CC → 2CC—C) on reduced molybdena–silica at room temperature. The initial homologation activity was enhanced by grafting the methylene species onExpand
Kinetics and catalytic studies of ethene homologation over silica-alumina supported reduced MoO3 catalysts
Abstract Silica-alumina (28.61% Al2O3) supported reduced MoO3 catalysts were found to be most active and selective for ethene homologation at a sufficiently low partial pressure of H2 in theExpand
