Sentence examples for catalyst ages from inspiring English sources

The comprehensive model is validated over real driving conditions for different catalyst ages.

Since the catalyst ages more slowly in the presence of the higher H2O/H2 conditions, it is concluded that water alone does not account for the deactivation and that there is a deactivation pathway that involves the assistance of CO.

It is seen that the intrusion of Fe, Ni, and Ca does not change significantly as a function of age; however, as the catalyst ages, an accumulation of the metals at or near the surface of the particle occurs.

FCC particles are partially composed of active alumina and zeolite phases that perform the precracking and cracking, respectively.[ 1– 3] As the catalyst ages, the harsh physical and chemical process conditions cause a decline in the overall cracking capability of FCC catalyst particles.

Catalyst ageing in oxidizing conditions increased the formation of N2O.

Kinetic and catalyst aging data were obtained from bench-scale tests.

Catalyst aging and higher temperature reduced the catalyst's ability to adsorb NH3.

Specifically, we investigated the effects of catalyst aging, space velocity and catalyst temperature on the regime transition.

This indicates that the lab-scale catalyst ageing procedure effectively mimics the initial catalyst deactivation observed in the pilot plant.

Catalyst aging is accounted via the update of a single scalar parameter in the model.

It is well-known that during the hydroprocessing of heavy feeds, catalyst aging is counterbalanced by continuously increasing reaction temperature.
