This work presents an example of the design and manufacture capabilities that 3D printing can introduce in ca-talysis. A multi-purpose catalyst, with fast heat and mass transfer and low-pressure drop has been designed andmanufactured by 3D printing. The novelty of the methodology is the combination ...

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...

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...

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 ...

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...
