Ni/Al2 O3 and Ni–Cr/Al2O3 catalysts prepared with melt salts of Ni and Al (Al/Ni=0.5) were studied by magnetic measurements, electron microscopy and catalytic properties. An increase in the catalytic activity and stability ...

The water gas shift reaction (WGSR) is recognized as an important step in the production of high pure hydrogen for several applications in the chemical and petroleum industries, as well as in fuel cells and mobile vehicles. ...

Chromium and potassium-doped iron oxides are widely used as industrial catalysts in the dehydrogenation of ethylbenzene to produce styrene. They have several advantages but deactivate with time, because of the loss of ...

The high-temperature shift (HTS) reaction is an important step in industrial processes and gas purification. Although the catalyst shows a stable performance, the search for non-toxic systems is much needed, especially due ...

Propene is used as a raw material for thermoplastic resins, adhesives and acrylic derivatives, being obtained mainly by steam cracking naphtha and natural gas. However, the oxidative dehydrogenation of propane reaction ...

Hexavalent chromium (Cr(vi)) is an noxious and highly toxic heavy metal that presents a serious threat to human health if present even in low concentrations in drinking water. Photocatalytic reduction of Cr(vi) to its less ...

Most promising catalysts for synthesising unsaturated fatty alcohols are based on group 8 metals with a promoter like tin, because the process can be carried out in moderate conditions, and these metals are less toxic than ...

A desidrogenação catalítica do etilbenzeno em presença de vapor d´água é, sem dúvida, a principal via de produção de estireno, um produto de alto valor comercial, amplamente utilizado na manufatura de borrachas e vários ...
