The results of the present paper confirm that propylene formation on x Mo/21V/Nb catalysts is due to the presence of acid sites of weak and moderate strength (Brönsted acid

The spectra of the A-3 fraction (Figure 2), obtained in the third separator the first condition of extraction, had signals identical to the ones described in the literature for the

corresponding to the fourth mass loss event detected by the TG/DTG analysis, the IR spectra of the niobium complex that decomposed at 400° and 600°C show a band corresponding to

The thermodynamic state relations of the mixture are derived from two equations representing the Gibbs free energy in terms of temperature, pressure and concentration for the

In this paper we present the pure-component equilibrium data for adsorption of methane, ethane, and butane on the nanoporous activated carbon material prepared using coconut shell

For this reason, other monoterpenes (alpha-pinene, beta-pinene and camphor) were used as substrates. These compounds were shown to be metabolized by the selected strain,

Abstract - The production of manganese dependent peroxidase (MnP) by Phanerochaete chrysosporium and the level of decolorization of 13 dyes were evaluated using static and

The most common method to date for the enantiomeric resolution of ibuprofen enantiomers and chiral materials in general is high performance liquid chromatography.. For the
