Hydrodeoxygenation of m-cresol over gallium-modified beta zeolite catalysts
Ga-modified H-Beta (Ga/HBEA) zeolites were evaluated and compared to other Ga-containing catalysts supported on SiO2 and ZSM-5 (MFI) for the hydrodeoxygenation of m-cresol, a model compound representative of lignin-derived phenolics. The products include toluene, benzene, xylene, light hydrocarbons, as well as phenol and other oxygenated compounds. The appearance of bicyclic compounds suggests ...
متن کاملEffects of Dealumination and Desilication of Beta Zeolite on Catalytic Performance in n-Hexane Cracking
Catalytic cracking of n-hexane to selectively produce propylene on Beta zeolite was carried out. The H-Beta (HB) (Si/Al = 77) zeolite showed higher catalytic stability and propylene selectivity than the Al-rich HB (Si/Al = 12), due to its smaller number of acid sites, especially Lewis acid sites (LAS). However, catalytic stability and propylene selectivity in high n-hexane conversions were stil...
متن کاملNitrate Removal from Aqueous Solution by Using Modified Clinoptilolite Zeolite
Background & Aims of the Study: Nitrate is one of the most important pollutants that its reduced form, nitrite, can cause serious problems for human health and environment. Adsorption with cheap sorbents such as Zeolite is the best way for removal of this pollutant. So this study aimed to apply modified Clinoptilolite Zeolite for nitrate removal. Materials & Methods...

متن کاملSynthesis of Cumene by Transalkylation over Modified Beta Zeolite: a Kinetic Study
In the present study, transalkylation of 1,4-diispropylbenzene (DIPB) with benzene in the presence of modified beta zeolite was performed to produce cumene in a fixed bed reactor. Beta zeolite was exchanged with cerium in order to modify its catalytic activity. Activity of the modified catalyst was evaluated in the range of temperature 493K–593K, space time 4.2 kg h/kmol–9.03 kg h/k mol and ben...
