Silicoaluminophosphate molecular sieves as potential catalysts for hydroisomerization of alkanes and alkenes

Effect of silicon precursor on silicon incorporation in SAPO-11 and their catalytic performance for hydroisomerization of n -octane on Pt-based catalysts

“…Therefore, many scientists focused on the research of the effective hydroisomerization catalysts [3][4][5][6][7][8][9][10] . Among these catalysts, SAPO-11 based catalyst is one of the promising catalysts in hydroisomerization of n -alkanes because it has moderate acidity and appropriate pore structure [11] . SAPO-11 is formed by silicon incorporation into the framework of AlPO-11, leading to the formation of acid sites.…”

Recent Advances in the Preparation and Applications of Organo‐functionalized Porous Materials

“…Porous materials are solid materials with a defined porosity and are naturally available or can be synthesized through simple self‐assembly of structure‐directing agents (SDA) and the required precursors using hydrothermal or solvothermal or ionothermal approaches. Typically, a material is called as porous if its internal pores are accessible for gas molecules or, in some cases, for liquids or solids . Depending on the nature of the pores, the textural parameters, and the adsorption properties of these materials will be changed.…”

Effect of preparation method on the bimetallic NiCu/SAPO-11 catalysts for the hydroisomerization of n-octane

“…SAPO-11 with AEL topology has one-dimensional ten-membered ring channels. Due to the suitable pore structure and moderate acidity, SAPO-11 is considered as a potential materials for the hydroisomerization of n -alkanes [10] . Noble metals, such as platinum and palladium, are usually applied as the metal site [11][12][13][14][15] .…”

“…The hydroisomerization catalyst, as a bifunctional catalyst, has both metal and acid sites. The dehydrogenation/hydrogenation of the alkane proceeds on the metal sites, and the isomerization and cracking proceed on the acid sites [10,22] . Besides, the hydrogenolysis of the alkane can be catalyzed by the metal sites.…”
