Catalytic evaluation of small-pore molecular sieves with different framework topologies for the synthesis of methylamines

Adsorptive characterization of porous solids: Error analysis guides the way

“…Second MOF is the fully microporous UiO-66 [18], which also gained significant attention because of excellent stability and interesting properties [19][20][21][22]. Sigma-1, a microporous zeolite and member of the DDR structural topology, known for its high separation performance in membrane and adsorptive processes, http incorporates aluminium into the framework, making the material also suitable for catalysis [23][24][25]. c-Alumina is chosen as representative for mesoporous metal-oxide supports, which are used frequently in heterogeneous catalysis [26][27][28].…”

Unexpected crystal growth modifier effect of glucosamine as additive in the synthesis of SAPO-35

“…The cages are accessible through eight-ring windows with dimensions 3.6x4.8 Å that generate channels in two directions [13]. This material is used as adsorbent or catalyst in different processes and reactions [20,37,38].…”

Shape-selective synthesis of methylamines over the RRO zeolite Al-RUB-41

“…Chabazite, a small pore zeolite containing cages with 8-membered windows, was previously introduced as a selective amination catalyst [12]. Chabazite proved indeed highly shape selective and produced only small amounts of TMA, with MMA and DMA as the principal amination products.…”

“…A large body of further work focused on the shape-selective properties of small pore zeolites containing typically cages that can be accessed via 8-membered ring pore windows [12][13][14][15][16][17][18][19]. Active and selective amination catalysts are for instance H-Rho, H-chabazite, and H-levyne zeolites.…”
