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… 



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 the

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 on

Selective Propene Synthesis from Ethene without Metathesis on Silica Supported Cobalt Catalyst

Selective chain propagation of ethene to propene (ETP reaction) was made on silica supported cobalt (Co/Si0 2) catalyst. It was suggested that the proper conditions for the chain propagation reaction

Attempt to yield light hydrocarbons including C3 fraction by supplying ethene and syngas on Co/SiO2 catalyst

When a 1:2 gas mixture of CO and H2, namely syngas, was contacted onto Co/SiO2 catalyst at 513 K with low pressure such as 0.2 kg/cm2, G, methanation was preferentially promoted, whereas chain

Selective Dimerization of Ethylene to 1-Butene with a Porous Catalyst

It is reported that a metal–organic framework catalyzes ethylene dimerization with a combination of activity and selectivity for 1-butene that is premier among heterogeneous catalysts.

Homologation of n-alkanes on metal films. A novel aspect of metal—carbene chemistry

A novel highly selective reaction has been discovered in the catalytic conversion of n-alkanes in hydrogen on unsintered tungsten films at 420 K. In addition to hydrocracking, substantial formation

Homologation of ethylene without metathesis on silica supported ruthenium catalyst

A 1:1 mixture of 12C2-C2H4 (H2C=CH2) and 13C2-C2H4 (H213C=13CH2) was contacted on Ru/SiO2at 200oC. Propylene (homologation) was observed without 13C1-C2H4 formation (metathesis reaction). This might

Insights into the Reaction Mechanism of Cyclohexane Oxidation Catalysed by Molybdenum Blue Nanorings

Molybdenum blue (MB), is a polyoxometalate with a nanoring structure comprising Mo5+–O–Mo6+ bridges, which is active for the catalytic oxidation of cyclohexane to cyclohexanol and cyclohexanone.
