In this article, the catalytic activity of bis[2-(p-tolyliminomethyl)phenolato] copper(II) complex was studied, for the first time, in the oxidation of various primary and secondary alcohols to the corresponding aldehydes or ketones. The effect of different solvent was studied in the oxidation of benzyl alcohol and methanol was chosen as the reaction medium. Also the effect of different oxidant...

Experiments of propane and propene steam reforming have been performed over a Pd–Cu/c-Al2O3 catalyst and over a Ni/NiAl2O4 catalyst. Over the palladium-based catalyst, the steam reforming of propene is faster and more selective than steam reforming of propane. Over the Pd catalyst, the steam reforming of propane is likely inhibited by site poisoning. In contrast, over Ni-based catalyst the refo...

The selective propane oxidation catalyst MoVTeNb oxide M1 was investigated by microwave conductivity, synchrotron X-ray photoelectron, soft X-ray absorption and resonant photoelectron spectroscopy under reaction conditions to identify the influence of steam on the electronic bulk and surface properties. Steam significantly increases both the conversion of propane and the selectivity to the targ...

Enzymes of the AlkB and CYP153 families catalyze the first step in the catabolism of medium-chain-length alkanes, selective oxidation of the alkane to the 1-alkanol, and enable their host organisms to utilize alkanes as carbon sources. Small, gaseous alkanes, however, are converted to alkanols by evolutionarily unrelated methane monooxygenases. Propane and butane can be oxidized by CYP enzymes ...

Propylene is an important raw material and extensively used in the petrochemical industry. There has been a continuously growing demand for propylene in recent years around the world1–3. The majority of propylene is produced as a byproduct from processes such as steam cracking of naphtha and fluid catalytic cracking (FCC)4,5. Additional sources of propylene included dehydrogenation of propane, ...

The primary sources and atmospheric chemistry of C2-C5 alkanes were incorporated into the atmospheric chemistry general circulation model EMAC. Model output is compared with new observations from the NOAA/ESRL GMD Cooperative Air Sampling Network. Based on the global coverage of the data, two different anthropogenic emission datasets for C4-C5 alkanes, widely used in the modelling community, ar...
