What Role Does Temperature Play in Catalyst Deactivation?
High temperatures can lead to catalyst deactivation through sintering, coking, or poisoning. Sintering involves the agglomeration of catalyst particles, reducing their active surface area. Coking refers to the deposition of carbonaceous materials on the catalyst surface, blocking active sites. Poisoning occurs when impurities bind to the active sites, rendering them inactive. Therefore, maintaining an appropriate temperature is essential to prolong catalyst life.
