Dealuminated Beta Zeolite Modified by Alkaline Earth Metals

Karolina Chalupka, Renata Sadek, Laetitia Valentin, Yannick Millot, Christophe Calers, Magdalena Nowosielska, Jacek Rynkowski, Stanislaw Dzwigaj

Alkaline Earth metals (Mg, Sr, and Ca) were incorporated into the dealuminated mesoporous beta zeolite (DeAlBeta) by the two-step postsynthesis method. Physicochemical properties of both unmodified and alkaline Earth metal-modified DeAlBeta zeolite were characterized by XRD, DR UV-vis, FTIR, TPD of…

CO 2 methanation over LDH derived NiMgAl and NiMgAlFe oxides: Improving activity at lower temperatures via an ultrasound-assisted preparation

Michel Obeid, Christophe Poupin, Madona Labaki, Samer Aouad, Sharad Gupta, Haingomalala Lucette Tidahy, Aida Younis, Ferdaous Ben Romdhane, Eric Gaigneaux, Josefine Schnee, Edmond Abi-Aad, François Delattre

Within the idea to catalyze CO 2 methanation NiMgAl and NiMgAlFe oxides were synthesized by the layered double hydroxide route using co-precipitation and ultrasound-assisted co-precipitation. MgAl and MgAlFe oxides-supported Ni materials prepared by the impregnation method were used as references.…
