Effects of toluene on thiophene adsorption over NaY and Ce(IV)Y zeolites

Selective Preparation of trans-Carveol over Ceria Supported Mesoporous Materials MCM-41 and SBA-15

“…This trend of increasing of Brønsted acidity after loading Ce on silicate or alumosilicate materials has been already described previously [22,23]. The amount of weak Lewis acid sites increases in case of loading ceria to mesoporous SBA-15.…”

Synthesis of bimetallic–organic framework Cu/Co-BTC and the improved performance of thiophene adsorption

“…So far, a bunch of adsorbents have been reported for desulfurization, such as metal oxides, 13 active carbon, 14 zeolites, [15][16][17] mesoporous materials 18,19 and metal-organic framework (MOF) materials. [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34] Among them, MOFs are getting more and more interest in adsorption desulfurization in recent years because of the high specic surface areas, highly ordered threedimensional pore structures, and easy modication of pore size and shape.…”

Adsorption desulfurization of model gasoline by metal–organic framework Ni3(BTC)2

“…Various kinds of adsorbents, including zeolites [7][8][9][10][11] , activated alumina [12] , activated carbons [13] , and other mesoporous materials [14,15] have been explored for desulfurization of fuels. Besides some basic characteristics (high specific surface area, large pore volume and suitable pore diameter), the adsorption mechanism involving the adsorbent -sulfur compounds interaction is demonstrated to be the key factor for superior desulfurization capacity.…”

“…Besides some basic characteristics (high specific surface area, large pore volume and suitable pore diameter), the adsorption mechanism involving the adsorbent -sulfur compounds interaction is demonstrated to be the key factor for superior desulfurization capacity. So far, some adsorption mechanisms including π -complexation [8,16] , direct sulfur-metal (S-M) interaction [9,11] , acid-base interaction [17] , Van der Waals' force [18] , as well as hydrogen-bond formation [19] have been reported. Among them, only the first three mechanisms have been proposed to be responsible for the improved desulfurization selectivity.…”
