Sentence examples for accelerated deactivation from inspiring English sources
In this present work, accelerated deactivation of hydrotreating catalysts was studied.
However, the effect of carbonaceous deposition during accelerated deactivation tests might have been overestimated compared with that during practical hydrotreating.
Furthermore, while the increased catalyst temperatures result in an accelerated deactivation of the unstable catalysts (Pt,Ir), heat integration leads to a complete compensation of this acceleration.
The model can qualitatively describe coke and metal deposition profiles found in hydroprocessing catalyst pellets, and the accelerated deactivation observed near the end of the catalyst life.
They showed high HDS, hydrogenation and hydrodenitrogenation activities in co-HDT of the mixed SRGO/SO feedstock as well as catalyst stability against to accelerated deactivation.
It was possible to determine MMOC of an ARDS catalyst system within 45 50 days by accelerated deactivation test using a high metal feed (e.g., Boscan crude).
Both KCNE1 mutations significantly accelerate deactivation at all voltages compared to wild type KCNE1.
Here we demonstrate that V287R increased the steepness of the steady state activation curve and slowed activation while accelerating deactivation kinetics.
Alanine substitution at L532 produced little perturbation of activation or inactivation [45], whereas substitution with tryptophan (a bulkier hydrophobic residue) has been reported to accelerate deactivation rate, but to have comparatively little effect on activation rate [44].
Thus Mal suppressed ICl on transition to negative voltages, accelerating deactivation and reducing the magnitude of the current, but the effect on current amplitude was evident primarily at the upper end of the phyisological range of Mal concentrations.
A certain amount of axial dispersion is found to actually improve the performance of the reactors in some cases due to the "washing out" of the hot spots which cause accelerated catalyst deactivation.
