Quantification and key factors in delamination of (Mg1-yNiy)1-xAlx(OH3)x·mH2O
Dispersions of delaminated layered double hydroxides (LDH) contain nanosheets of interest for single particle studies and for preparation of different types of clay mineral-clay mineral or clay mineral–polymer nanocomposites and coatings. Reproducible methods were currently benchmarked, key...
Pressure Swing Adsorption (PSA) for hydrogen purification using UTSA-16 metal-organic framework
Olefin – Paraffin Separation using Calcium-ETS-4
The properties of calcium-modified ETS-4 are studied focusing on olefin–paraffin separation by PSA (Pressure Swing Adsorption), specifically a stream containing CH4/C2H6/C2H4. The effect of activation temperature of Ca-ETS-4 is studied to perform a kinetic separation, with the aim of excluding...
Adsorptive desulfurization of diesel by regenerable nickel based adsorbents
An experimental investigation on a vapor phase adsorptive desulfurization process for diesel is described based on NiMCM-41 and NiY as sulphur selective adsorbents. Under optimized conditions [pressure 4 bar (absolute) and temperature 350 °C] the NiMCM-41 adsorbent could bring down the sulphur...
Development of CO2 sorbents for the SEWGS process using high throughput techniques
The presentation describes the search for new SEWGS sorbents by using high throughput techniques. In total 432 new sorbent formulations have been prepared, partly characterized and more than 300 sorbents have been evaluated under realistic conditions in a three cycle adsorption-desorption test. From...
