Quantification and key factors in delamination of (Mg1-yNiy)1-xAlx(OH3)x·mH2O

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1364108

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 paramete...

Olefin – Paraffin Separation using Calcium-ETS-4

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1163020

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 paraf...

Adsorptive desulfurization of diesel by regenerable nickel based adsorbents

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1038131

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 conce...

Development of CO2 sorbents for the SEWGS process using high throughput techniques

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+912209

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...

Utilization of CO2 via Catalysis in Ionic Liquids

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1272455

Carbon dioxide, CO2, is a molecule of intense current interest, as it is the primary chemical motor leading to the calamity of climate change. CO2 is also a viable, sustainable, yet challenging C1 feedstock, and the preferred reagent over other C1 sources such as phosgene, COCl2, and CO. Fundamental...
