Hydrocarbon conversion catalysts suffer from deactivation by deposition or formation of
carbon deposits. Carbon deposit formation is thermodynamically favored above 350° C …

Solid catalysts are the workhorses that convert feedstock molecules into fuels, chemicals
and materials. Solid catalysts are highly complex, porous, multi-elemental and often …

Simultaneous catalytic elimination of NO and N2O from exhausts is an ideal solution for
nitric or adipic acid plants. Herein, Fe-based zeolite catalysts were applied for the NH3–NO …

Solid catalysts are complex, multi-component materials with large interparticle
heterogeneities that hamper statistically relevant in-depth catalyst characterization. Here we …

A combination of X-ray ptychography and X-ray fluorescence tomography (XRF) has been
used to study the fragmentation behavior of an individual Ziegler–Natta catalyst particle,∼ …

Porous materials are outstanding catalysts in various reactions using confinement and
shape selectivity effects. Unsurprisingly, extensive research has been conducted on …

The performance of functional materials is either driven or limited by nanoscopic
heterogeneities distributed throughout the material's volume. To better our understanding of …

Ni contamination from crude oil in the fluid catalytic cracking (FCC) process is one of the
primary sources of catalyst deactivation, thereby promoting dehydrogenation–hydrogenation …

Ziegler-type catalysts are the grand old workhorse of the polyolefin industry, yet their
hierarchically complex nature complicates polymerization activity–catalyst structure …

Cyclone separators, which have an important role in the recovery of catalysts, constituted
one of the aims of the study. In the work to be done, the pressure drop occurring during the …
