Alkaline silicon extraction and acid aluminium recovery enable selective, high-purity zeolite precipitation from refractory mineral residues at lower energy.
Using water-soluble ODSO in one aqueous gel forms crystalline zeolite and amorphous binder together, cutting DSO disposal waste and process steps.
Simultaneous ammonium hexafluorosilicate and ammonium hydroxide treatment creates mesoporous zeolites with fewer steps and lower cost.
Clay, silica sol, and sodium salt bind zeolite particles to improve abrasion resistance and flowability during adsorption-tower packing.
This case uses templated delamination of FAU zeolite to combine microporous catalysis with mesoporous access for larger species.
Inorganic salts mediate alkaline leaching to increase mesopore volume while preserving crystallinity and eliminating toxic organic templates.
Titanium atoms bonded to four bridging oxygen atoms enhance catalytic selectivity for naphtha in hydrocracking reactions while maintaining structural stability.
Hierarchically ordered crystalline microporous materials with cubic symmetry enhance diffusion rates through controlled self-assembly.
A continuous zeolite synthesis process uses controlled fluid flow to produce uniform crystals.
