Methanol-to-olefin (MTO) conversion is one of the most successful non-petrochemical routes for producing light olefins. Silicoaluminophosphate zeolite SAPO-34 is one of the best industrial catalysts ...
Gels with $CaO-Al_2O_3-SiO_2$ ratios from 1: 1: 3 to 1: 1: 10 were prepared with $SiO_2$ supplied as the 150 Å-sol "Ludox" and reacted under hydro thermal conditions ...
To make stable zeolites—porous inorganic materials used as industrial catalysts—researchers often convert the zeolites’ internal structure, transforming looser phases into more stable, denser forms.
High-strength NaX zeolite microspheres with 75-150 μm particle size (GXU-NaXs) were prepared by the in-situ conversion of geopolymer technology. GXU-NaXs exhibited good dynamic adsorption effect.
A porous crystalline membrane that selectively pulls water molecules out of a gaseous reaction mixture could improve the efficiency of industrial processes such as methanol synthesis (Science 2020, ...
