Abstract |
|
In an ideal catalytic contactor, the energy necessary for the reaction would be exclusively delivered to the active sites of the catalyst. This ideal concept is in contrast with conventional operation of catalytic reactors, where heat is generally supplied through the reactor wall and unnecessary heating of the fluid phase, catalyst support and reactor materials occur.
In addition to a better energy efficiency, other benefits of direct catalyst heating include a higher selectivity in series-parallel reactors with a valuable intermediate product, where further (unwanted) reaction would be prevented by the desorption of the product into a comparatively colder fluid stream.
In this talk, the concept of direct catalyst heating will be discussed, together with some of the practical challenges involved. Specific examples will be provided based on alternative heating modes that use microwave (with zeolite and perovskite catalysts), laser (with Au and Pd plasmonic nanoparticles) and magnetic field (with magnetite nanoparticles) sources.
