The ability to determine whether a pore size distribution can be fitted to a given set of experimental data is relevant to the development of pore network models of the internal structure of activated carbons and other amorphous adsorbents. A closely

Nitrogen sorption is a commonly used experimental technique for the characterization of solids that are primarily mesoporous. The standard nitrogen adsorption experiment can also detect pores at the lower end of the macropore range, up to perhaps 300

Predicting adsorption over a range of operating conditions and the improvement of the adsorbent itself are two important aspects that arise in the industrial application of adsorption. Both of these aspects can be addressed using molecular simulation

Microporous carbons are typically characterized as a pore size distribution of slit-shaped model pores. Since these characterizations are used to interpret physical properties such as the degree of microporosity, adsorption behaviour, molecular sievi

The critical path analysis (CPA) of Ambegaokar et al. (1971) suggests that transport in random systems with a broad enough distribution of conductances is dominated by a controlling conductance of a critical magnitude. The present short, yet systemat

Adsorption of methane was measured on BPL-6 activated carbon, and simulated using the Grand Canonical Monte Carlo method in 40 slit-shaped pores ranging in width from from 0.63 to 5.72 nm (1.65−15 methane molecular diameters). The simulations were

Smoluchowski's theory for orthokinetic coagulation of spheres is extended to aggregation during precipitation of calcium oxalate monohydrate. Physical models for hydrodynamics and deposition in a binary aggregation event are combined to determine the

A new theory for the prediction of multicomponent adsorption equilibrium in non-crystalline porous solids is presented: the multispace adsorption model (MSAM). This theory allows for the inherent nonuniformity of the adsorbed phase by describing sepa

We present a method for the simulation of catalyst fouling at the particle and reactor levels. At the particle level, diffusion and reaction are described by a continuum model. The accessible pore surface area and the effective diffusivity are obtain

Porous media such as sedimentary rocks and soils are often anisotropic in their resistance to flow of fluids, solutes, heat, and electrical current. Lattice-based calculations of the transport properties of pore networks are of considerable interest,
