Sentence examples for the catalyst where from inspiring English sources
"That was the catalyst where everything clicked".
It was shown that optimum selectivity with the maximal isomer yield was obtained for the catalyst where calcination and Pt acid decomposition were hold simultaneously at high temperature.
Therefore, for the zoned sample, C3H6 was oxidized closer to the inlet portion of the catalyst, where a higher density of Pt was located, leaving the rest of the catalyst available for NO oxidation.
The flowrate does affect the reaction time, and an over-accelerated methanol injection rate will definitely lead to a rapid coking of the catalyst, where the ideal thermodynamics could be achieved when all the chemicals in the MTH system (catalysts are not included) are converted into the cokes.
A growth model basing on the HRTEM characterization and thermodynamic analysis is suggested in which the CNT nucleates and grows on the active surface area of the catalyst where S accumulates in the form of an FeS Fe eutectic, and the S distribution on the catalyst particle surface determines the number of CNT layers.
The latter, for example, is a key factor for the catalytic performance of the FCC catalyst because pore clogging through coke formation or metal deposition can seriously hinder feedstock molecule diffusion into the catalyst, where the heavy hydrocarbon fractions are cracked.
Their structure properties and dehydrogenation behaviors were also evaluated and compared with the catalysts where commercial mesoporous Al2O3 used as supports.
Pt loading was also observed to influence the pore volume and aromatization activity of the catalysts, where the catalyst exhibited decrease in pore volume above 0.4 wt.% Pt loading.
In the case of the Ni Cr-oxide aNi Cr-oxidelytic system, hydrogen forms over the former candlyst iNTKropane oxidation, migrates through the gas phase to the latter catalytic where NOx isystemvated withydrogenrmation oformsrate structures which interact with the said hydrover giving the products oformeroverall reacatalyst2 and H2O.
This was not the case for the Pd/Ce0.75Zr0.25O2 catalyst, where both NO and ethanol adsorb and decompose on the partially reduced mixed oxide surface.
The Ru complex worked as a relay to transport the holes formed on the CdS surface to the RuO2 catalyst where water oxidation takes place.
