Hydrotreating is one of the most used process for eliminating impurities in heavy oil
fractions, in which fixed-bed reactor has been used much more extensively. Nevertheless …

Combustion in inert, catalytic and combustible porous media occurs under the influence of a
large range of geometric length scales, thermophysical and thermochemical properties, and …

Over the past two decades percolation theory has been used to explain and model a wide
variety of phenomena that are of industrial and scientific importance. Examples include …

An analysis method, based on percolation theory, was recently proposed for the
determination of the connectivity of porous solids from nitrogen sorption measurements. In …

Heterogeneous catalysis is widely used in chemical, refinery, and pollutioncontrol
processes. For this reason, achieving optimal performance of catalysts is a significant issue …

A versatile pore network model is used to study deactivation by coking in a single catalyst
particle. This approach allows to gain detailed insights into the progression of deactivation …

The purpose of this review is to provide a comprehensive overview of mathematical
procedures that can be used to describe the release of drugs from inert matrix systems. The …

A theoretical model for the enzyme catalysed isomerisation reaction in a packed-bed
reactors made up of microporous particles is discussed. The system is described in terms of …

A fractal pore model is presented. These fractal pores are the constituents of the pore
network of amorphous catalyst particles. The model is constructed in a fundamental and …

Optimization of the three-dimensional pore structure of a hydrodemetallation catalyst is
described. A random network model with different connectivities has been used. The …
