Removal of volatile odorous organic compounds over NiAl mixed oxides at low temperature

Recent Advances in the Catalytic Oxidation of Volatile Organic Compounds: A Review Based on Pollutant Sorts and Sources

“…It produces low waste products and does not require the addition of any reagents during the desulfurization processes. [963][964][965] CeO2 is well known as a major catalyst for CH3SH catalytic decomposition. 966 CeO2 nanoparticles were prepared by He et al 967,968 using a convenient microwave-assisted sol-gel method.…”

“…Catalytic abatement is regarded as an effective method for complete removal of CH 3 SH as it is both environmentally friendly and economically feasible. It produces low-waste products and does not require the addition of any reagents during the desulfurization processes. − …”

Enhanced adsorption performance for aromatic sulfur compounds over a hierarchical structured AgX zeolite

“…6,7 Its application is limited by operation at harsher conditions of high temperature (300-350 C) and high hydrogen pressure (2-10 MPa). 8,9 Recently, one particularly effective strategy has been adapted using solid adsorbents to remove organosulfur compounds and its efficiency is closely related to the choice of the adsorbent. Herein, the new task of developing efficient adsorptive desulfurization (ADS) technology has proposed the need for outstanding adsorption efficiency and stability of adsorbents.…”

Oxidative Dehydrogenation of Propane over Ni–Al Mixed Oxides: Effect of the Preparation Methods on the Activity of Surface Ni(II) Species

“…The Ni-Al LDH precursors with Ni:Al molar ratio of 4:1 were prepared by the following three modified coprecipitation methods: constant pH coprecipitation [22], variable pH coprecipitation [16] and urea hydrolysis method [23], in all of which NiCl 2 •6H 2 O (98.0%, Aladdin) and AlCl 3 •6H 2 O (97.0%, Aladdin) were used as metal sources.…”

“…Hence we reasoned that the above doubt could be related to the selection of appropriate preparation methods. Certainly, there are various synthesis routes for LDH precursors, such as coprecipitation [16,22,23], ion-exchange method [24], hydrothermal method [25,26], ultrasound irradiation [27,28] and reconstruction [29,30], etc. It is particularly important to explore a suitable preparation method of Ni-Al LDH precursors to improve the catalytic performance of the Ni-Al MMO catalysts at high temperature.…”
