A facile approach for fabricating highly active ZrCeZnO in combination with SAPO-34 for the conversion of syngas into light olefins

Light olefin synthesis from a diversity of renewable and fossil feedstocks: state-of the-art and outlook

“…For example, in the CO 2 hydrogenation reaction, co-feeding with CO is known to significantly reduce the rate of RWGS, because of Le Chatelier's principle. 393…”

“…For example, in the CO 2 hydrogenation reaction, co-feeding with CO is known to significantly reduce the rate of RWGS, because of Le Chatelier's principle. 393 Fig. 30d shows the selectivity-conversion dependence based on the previously published data for CO 2 hydrogenation.…”

MgO/CaO Nanocomposite Facilitates Economical Production of d-Fructose and d-Allulose Using Glucose and Its Response Prediction Using a DNN Model

“…An equimolar ratio of MgO to the CaO nanocomposite was prepared by following the coprecipitation method, as described elsewhere . Briefly, 20 mL of 0.1 M MgSO 4 and 20 mL of 0.1 M Ca­(OH) 2 were mixed together and stirred continuously for 10 min to obtain a homogenous suspension of Ca and Mg salts at 1:1 M ratio.…”

“…An equimolar ratio of MgO to the CaO nanocomposite was prepared by following the coprecipitation method, as described elsewhere. 25 Briefly, 20 mL of 0.1 M MgSO 4 and 20 mL of 0.1 M Ca(OH) 2 were mixed together and stirred continuously for 10 min to obtain a homogenous suspension of Ca and Mg salts at 1:1 M ratio. To this solution, 10 mL of 2.0 M NaOH was dropwise added and allowed to react for 30 min at 60 °C, followed by aging at room temperature (RT, 27 °C) overnight.…”

On the reaction mechanism of MnOx/SAPO-34 bifunctional catalysts for the conversion of syngas to light olefins

“…Most of oxides contained Zn: ZnO, 11 ZnCrOx, 8,[12][13][14][15][16][17][18][19] ZnZrOx, 10,20,21 ZnAlOx, [22][23][24] Zrpromoted ZnAlOx, 25 La-doped ZnAlOx, 26 Zn spinels, 27 ZnCeZrOx. [28][29][30][31] Alternatively, MnOx, 32 MnGaOx, 33,34 or ZrInOx, 35 was used. The zeotype corresponded most of the time to microsized) or to mesoporous M-SAPO, 8,11,32 hierarchical SAPO-34, 21 nanosized SAPO-34, 12,25 SAPO-18, 13,18 SAPO-35, 18 various SAPOs, 24 AlPO-18, 36 SSZ-13, 17,20 .…”
