“…Even worse is that, as the reaction temperature increases, the selectivity towards aromatization products increases to a much greater extent than that of the desired olefin products. 7 Therefore, to improve the utilization rate of the C 5 -C 8 fractions and obtain high-value products, it is important to fabricate highefficiency catalysts suitable for C 5 -C 8 fraction dehydrogenation.…”
The K-affected metal–acid site balance of the Pt–K/Al2O3 catalyst is investigated. Increased K content leads to the loss of acid sites and better selectivity. However, it also leads to decreased Pt active sites, reducing the activity.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
