Catalyst Deactivation and Regeneration, decrease as time increases under otherwise steady state conditions. Such changes are seldom known in homogeneous reactions in which catalytic surfaces are not involved. From the point of view of experimental observation, such changes may or may not be correlated with the kinetic variables of importcognizant 发表于 2025-3-23 15:43:24

Metal Catalysed Skeletal Reactions of Hydrocarbons,emonstrate the reaction mechanisms and to correlate the changes of activity and selectivity with changes in electronic properties or changes in geometry of the metal aggregates. In spite of their great importance in petrochemistry, the mechanisms of hydrocarbons reactions on metal catalysts are muchDEI 发表于 2025-3-24 02:10:24
Dispersed Metal Catalysts,rol and gas purification, and in alternative fuel production. Bulk metal catalysts, . powders, reactor coatings or honeycomb structures, pose severe drawbacks in terms of catalyst efficiency (activity per weight of active component) and are therefore costly. In addition such catalysts show low therm允许 发表于 2025-3-24 02:48:33

Catalyst Deactivation and Regeneration,ance for the main reaction such as concentration or temperature since as will be seen they may be the result of parallel, independent chemical processes, or they may be associated with the chemical behavior of the reactants or products of the main reaction, or they may be the result of some degradation of the catalytic surface.
