Sentence examples for diffusion of the catalyst from inspiring English sources

To prevent diffusion of the catalyst, hydrogen chloride is added in the gas flow [36].

This lifetime enhancement occurs because the refractory metal inhibits the surface diffusion of the catalyst metals, slowing the Ostwald ripening of the catalytic particles and allowing them to grow CNTs for greater times, resulting in longer CNTs.

The mechanical compression forces applied to the pretreated material could cause deterioration of the wood matrix and thus influence the extent of diffusion of the catalyst during impregnation, as well as the heat transfer to the woody material [ 23, 26].

The new model is verified through comparison with the conventional differential tubular model using the fast reaction kinetics of the steam methane reforming process and neglected mass diffusion limitation of the catalyst.

This is likely because of the diffusion of the copper catalyst incorporated in the growth of the Si nanowires.

It acts as an electrode that provides the electrical contact for the CNTs, and it also forms a protective barrier layer against diffusion of the Ni catalyst and formation of NiSix.

The copper substrates were coated with nitride and oxide amorphous ceramic barrier coatings in order to prevent diffusion of the iron catalyst during growth.

By tuning the porosity of SiO2 shells (using C18TMS agent) and with the introduction of an appropriate amount of Cs dopant (via pre-deposition as well as post-impregnation), the diffusion efficiency of the catalysts and the surface property of Fe cores can be modified for better performance.

Modifying additions in amounts of 1 10 wt.% change the effective charge and redox properties of supported silver, the metal dispersivity and its surface diffusion, surface acidity of the catalyst and degree of coking in the process of oxidation of methanol to formaldehyde.

On the contrary, soluble redox catalysts can not only increase the reaction rate of Li2O2 formation but also avoid electrode passivation since the fast diffusion of the soluble redox catalyst would displace the formation of Li2O2 at a sufficient distance from the electrode surface.

Low yields can be attributed to the diffusion of reactant, catalyst, and product through the diaphragm of the divided cell.
