Zeolite catalysis is often affected by transport limitations, which significantly influence overall
performance. Introducing wide pores as molecular transport highways can reduce transport …

Nature mimicking implies the design of nanostructured materials, which can be assembled
into a hierarchical structure, thus outperforming the features of the neat components …

Hydrotreating of vacuum residue by ebullated-bed shows tremendous significance due to
more stringent environmental regulations and growing demand for lighter fuels. However …

Regulation of pore hierarchy has been an important subject in the design of industrial
catalysts. Synthesis of alumina without template/additive often results in poor control of …

A multiscale model is developed to describe the coupled flow, diffusion, heat-transfer, and
reaction processes at catalyst pellet and fixed bed reactor levels for heavy paraffin …

In this work, the gas–liquid mass transfer performance of rotating packed bed (RPB) with Al
2 O 3 sphere packing, in term of volumetric liquid-side mass transfer coefficient (k L ae), was …

A clean straightforward laser ablation method in deionized (DI) water is reported for the
synthesis of Molybdenum (Mo) and Nickel (Ni) nanoparticles (NPs). The structural …

In this work, a Random Needles Model is employed to investigate the effects of the
hierarchical pore structures and geometries for the extruded hydrodemetallization (HDM) …

The low effectiveness factor of catalyst pellet caused by high internal diffusion limitation is a
common issue in fixed‐bed reactor. Nevertheless, hierarchical structured catalyst provides a …

The design of hybrid pellet catalysts for dehydrogenation and metathesis of propane to
olefins was investigated. Reaction kinetics and mathematical models of pellet catalysts in a …
