Sentence examples for decrease the selectivity to from inspiring English sources

Hydrogen transfer reactions are prevalent at high conversions and help to decrease the selectivity to olefins as shown in Fig. 8.

Therefore, untreated catalysts promote selective formation of the symmetrical ketone, acetone, thereby decreasing the selectivity to the cross-ketone.

Increasing the support pore diameter decreases the selectivity to syngas and increases H2O and olefin selectivity.

The addition of small amounts of boron decreased the selectivity to acetonitrile in the whole range of Si/Al ratios studied.

Co3O4 promotes NOx reduction at low temperatures, but decreases the selectivity to NOx reduction especially at high temperatures through promotion of propane oxidation by oxygen.

Moreover, there is a strong dependence of the catalytic performance on the size of the Au particles: Au particles below 3 nm enhance the C2H2 conversion both in the absence and the presence of C2H4, without decreasing the selectivity to C2H4.

When large size of MoO3 crystallites were formed, cracking reaction, i.e., C C bond cleavage, occurred leading to non-selective total oxidation, resulting in decreasing the selectivities to acrolein and acrylonitrile.

The modification of the Fe/ZrO2 catalyst by alkali metal ions except for Li+ significantly decreased the selectivities to CH4 and lower paraffins and increased those to lower olefins and C5+ hydrocarbons, particularly C5+ olefins.

The conversion of cyclohexane decreased, while the selectivity to cyclohexanol and cyclohexanone increased with the increase of the apparent density.

This causes a strong decrease in the selectivity to maleic anhydride.

Opposite to the trend shown by 1-octene, enriching the reactant mixture with n-octane causes a noticeable decrease in the selectivity to styrene (Fig. 6).
