Cooperative effects of zeolite mesoporosity and defect sites on the amount and location of coke formation and its consequence in deactivation
TL;DR: In this paper, the mesopore generation and annealing of internal silanols in zeolites were investigated in n-pentane aromatization using model Ga/ZSM-5 catalysts.

IR studies of Fe modified ZSM-5 zeolites of diverse mesopore topologies in the terms of their catalytic performance in NH3-SCR and NH3-SCO processes
Kinga Góra-Marek,Kamila Brylewska,Karolina A. Tarach,Małgorzata Rutkowska,Magdalena Jabłońska,Minkee Choi,Lucjan Chmielarz +6 more
TL;DR: The results of the catalytic studies of the NH3-SCR process showed that the Fe-exchanged ZSM-5 sample prepared by direct synthesis route with amphiphilic organosilanes as a mesopore-directing agents presented the highest catalytic activity in the low temperature range comparing to the other catalyst studied as mentioned in this paper.

Maximizing Biojet Fuel Production from Triglyceride: Importance of the Hydrocracking Catalyst and Separate Deoxygenation/Hydrocracking Steps
TL;DR: In this article, the deoxygenation of triglyceride via hydrotreatment was carried out in a separate reactor prior to the hydrocracking step, which can cause significant imbalance between the metal and acid functions.

Unveiling coke formation mechanism in MFI zeolites during methanol-to-hydrocarbons conversion
Songhyun Lee,Minkee Choi +1 more
TL;DR: In this paper, the amount, composition, chemical nature, and deactivating effects of internal and external cookes were analyzed separately, and it was shown that internal coke is likely to have the polymeric structures of the methylated acenes connected via methylene bridges.

TL;DR: It is shown by on-line ICP-MS that the dissolution be-havior of as-synthesized Pt SACs is significantly different from that of metallic Pt/C, and Pt Sacs is confirmed to be more stable towards Pt dissolution, while significant amounts of sulfur leave the catalyst during oxidation.
