In this paper, we discuss the effects of catalyst load with respect to carbon powder for several Pt and Pb-based catalysts, using formic acid as a model molecule. The discussion is based on electrochemical tests, a complete ...

The influence of Pt addition (in very low concentrations) to a Ni/(10%)/Al 2O 3 catalyst in its catalytic performance during long-term experiments of dry reforming of methane was studied. The monometallic Pt(0.5%)/Al 2O 3 ...

In this paper, bimetallic PtGa and PtIn catalysts supported on multiwall carbon nanotubes and carbon Vulcan were used to study the hydrogenation of citral (alpha,beta-unsaturated aldehyde) in liquid phase to produce nerol ...

Biodiesel is a liquid fuel obtained from several renewable sources by transesterification reaction of triglycerides. Its development is related to a new tendency: the search for alternatives to petroleum-based energy ...

The need for environmental protection has demanded the searching nontoxic catalysts easily handled and discarded. This work deals with the use of aluminum as a substitute of chromium, in iron- and copper-based catalysts for ...

The reforming of natural gas feedstock in the presence of steam is the main industrial route to produce high purity hydrogen. However, this process also produces carbon oxides which can poison most hydrogenation catalysts ...

The liquid phase citral hydrogenation carried out at 70 °C and atmospheric pressure over Pt and PtSn catalysts supported on both activated carbon powder (C) and felt (ACf), was investigated. It was found that the addition ...

A key step in the preparation of asymmetric heterogeneous catalysts based on silica-supported rhodium and platinum chemically modified with chiral organotins, is the synthesis of optically pure tin derivatives. We report ...
