Characterization of various zinc oxide catalysts and their activity in the dehydration-dehydrogenation of isobutanol [PDF]

Journal of the Serbian Chemical Society, 2008
Mono and bifunctional zinc oxide catalysts were prepared to study their activity in the catalytic conversion of isobutanol. The prepared catalysts were characterized by X-ray diffraction analysis and nitrogen adsorption measurements.

Enhanced light olefins production via n-pentane cracking using modified MFI catalysts

Heliyon, 2022
n-pentane catalytic cracking was studied over a series of MFI zeolites with varying SiO2/Al2O3 ratios (30, 80, 280, 500, and 1500) using a fixed-bed reactor operated at temperature 550–650 °C.

Hydrogen Integration in Petroleum Refining

Chemical Engineering Transactions, 2012
There is a worldwide trend towards the production of cleaner gasoline and diesel. Legislation is placing increasingly tight limits on the sulphur content of fuels. There is also a worldwide trend towards processing heavier crude oils This requires increased levels of hydroprocessing, which places increased demands on hydrogen supply in refineries.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
