The presence of the catalyst provides selectivity toward kerosene formation even at high temperatures, but also very high temperatures are undesirable in an industrial scale because of the problems of deactivation of the catalyst.
The oxidation of nickel in the air or under humid conditions is a well-known phenomenon, but the reaction proceeds very slowly, because of the deactivation of the surface due to the formation of a thin oxide layer.
Results show that the collision of tip catalysts of growing CNCs to the substrate or other CNCs inhibits the smooth growth of CNCs because of the deactivation of the catalyst.
Because of the deactivation of eIF4E, the association of ATF4 with the MAP1LC3B promoter was inhibited, and autophagy was compromised.
Water tolerance is an important topic for low temperature NH3-SCR, because of the inevitable deactivation of the catalyst in the presence of water.
Catalytic cracking reactions, performed on commercial catalysts, are difficult to follow because of the simultaneous deactivation of the catalyst as consequence of coke deposition on catalyst surfaces during cracking of hydrocarbon molecules.
The widespread utilization and commercialization of hydrodechlorination (HDC) over Pd-based catalysts as a remediation technique has been impeded because of catalyst deactivation problems such as formation of carbonaceous deposits under the reductive environment of HDC.
The continuous catalyst flow rate in the reactor and its renewal are necessary because of catalyst deactivation.
Pd-Cu/ZrO2 was also stable and recyclable, in contrast to Cu/ZrO2, which suffered severe deactivation because of agglomeration of Cu particles during sorbitol hydrogenolysis.
