Gas phase thermal and oxidative dehydrogenation of ethane and propane are explored experimentally and mikrokinetically. Kinetic data for the elementary reactions postulated were adopted from the literature. The results show that oxygen plays a domina

Oxidative dehydrogenation of ethane to ethylene was studied using variously prepared Li/Dy/Mg/Cl mixed metal oxides as catalysts. The catalytic performance was found to be strongly dependant on the method of preparation and the LiCl content of the so

The incorporation of heteroatoms like N in activated carbons is of interest to modify the surface chemistry of the materials and, then, to improve their behavior as catalyst or catalyst support. In this work, N-containing activated carbon fibers have

The high quality COLSYS/COLNEW collocation software package is widely used for the numerical solution of boundary value ODEs (BVODEs), often through interfaces to computing environments such as Scilab, R, and Python. The continuous collocation soluti

Hydrodynamic cavitation was shown to be a powerful tool for the synthesis of nanostructured catalysts, ceramics, and piezoelectrics in high phase purities. The macro-, micro-, and nano- properties of solid-state materials could be controlled through

The sputtering rates of iron films and various steels exposed to argon–hydrogen pulsed-DC glow discharges in a commercial plasma-assisted chemical vapour deposition plant have been studied experimentally. The sputtering rate of iron was obtained fr

A mixed oxide catalyst containing Mo, V, and W was used for the partial oxidation of methanol. The relation between the structure and the degree of reduction of this mixed oxide catalyst and its catalytic performance was investigated by scanning elec

Pt black was exposed to n>-hexane/H2 mixtures between 483 and 663 K followed by O2 and H2 treatments at 603 K. XP and UP spectra were measured without exposing the samples to air. 20–30% carbon accumulated after hydrocarbon exposures. O2 removed mo

Fullerene blacks with 0.7–4.5 at% of nitrogen incorporated into their carbon framework were produced by feeding N 2 gas into the center of a carbon arc through a hollow graphite electrode. The formation of toluene-soluble fullerenes is effectively
