The surface area of porous materials is a widely-used parameter in catalysis and adsorption. The most-commonly applied model, Brunauer–Emmett–Teller (BET), bases the parameter to the mass of material. Though the model does have its limitations, c

An in situ thermal reactivation of a multi-walled carbon-nanostructure (MWCNT) is feasible with improved performance in the O2-mediated styrene synthesis, also called oxidative dehydrogenation of ethylbenzene (EB). The actual catalyst is the coke dep

Explaining the conversion and selectivity of a heterogeneous catalyst is often done separately. The general rule is that with high temperatures conversion increases but the catalyst becomes less selective to the desired product, as other pathways to

Determining the surface area of porous materials through the Brunauer–Emmett–Teller (BET) model is a common practice. The method is generally applied in commercial software packages, where the assumptions are sometimes accepted by the experimente

The thermal events typically encountered during the reactivation of inorganic catalytic supports have been investigated. For this, two relevant inorganic materials were studied; an amorphous silica and a gamma (γ) alumina. The materials were thermal

The thermal stability of porous sol-gel phosphosilicates was studied by comparing the textural features upon calcination between 400 and 550 degrees C. A significant loss of surface area and pore volume were observed; the first is due to thermal coar

Drastic improvements in styrene yield and selectivity were achieved in the oxidative dehydrogenation of ethylbenzene by staged feeding of O-2. Six isothermal packed bed reactors were used in series with intermediate feeding of O-2, while all EB was f
