CuH-ZSM-5 as hydrocarbon trap under cold start conditions.
Cold start tests are carried out to evaluate the performance of copper-exchanged zeolites as hydrocarbon traps under simulated gasoline car exhaust gases, paying special attention to the role of copper in the performance of these zeolites. It is concluded that the partial substitution of the protons in the parent H-ZSM-5 zeolite is highly beneficial for hydrocarbon trapping due to the formation...
متن کاملA hierarchical Fe/ZSM-5 zeolite with superior catalytic performance for benzene hydroxylation to phenolw
Phenol is an important industrial intermediate for the production of various chemicals such as bisphenol A, phenolic resins, caprolactam, alkylphenols and adipic acid. The cumene hydroperoxide process is the currently used industrial method to produce phenol. Its environmentally stressing aspects have spurred research to replace this process with more benign approaches such as the direct oxidat...
متن کاملA hierarchical Fe/ZSM-5 zeolite with superior catalytic performance for benzene hydroxylation to phenol.
We report the one-step synthesis of a highly active hierarchical Fe/ZSM-5 zeolite catalyst with a strongly improved lifetime in the selective hydroxylation of benzene to phenol with nitrous oxide; compared to the best Fe/ZSM-5 catalyst, the turnover number after 24 h on stream is almost four times higher.
متن کاملOrganosilane with gemini-type structure as the mesoporogen for synthesis of hierarchical porous ZSM-5 zeolite
A new kind of organosilane (1,6-bis (diethyl(3-trimethoxysilylpropyl)ammonium) hexane bromide) with a geminitype structure was prepared and used as a mesoporogen for the synthesis of hierarchical porous ZSM-5 zeolite. There are two quaternary ammonium centers along with double hydrolysable -RSi(OMe)3 fragments in the organosilane, which results in a strong interaction between this mesoporogen a...
متن کاملRole of Lewis acid sites of ZSM-5 zeolite on gaseous ozone abatement
In this work, chemical interactions between ozone and zeolite surface active sites are studied in order to propose a process for gaseous ozone removal. Synthetic ZSM-5 zeolites with three different Si/Al2 ratios and similar specific surface areas and microporous volumes were used in this study. Zeolite samples were characterised using Fourier Transform InfraRed spectroscopy (FTIR) and pyridine ...
