Development of an active, selective and durable water-gas shift catalyst for use in membrane reactors
(Elsevier Science, 2016-01)
Rh(0.6%)/La2O3 and Rh(0.6%)/La2O3(27 wt%)·SiO2 were assayed for the WGS reaction at 673 K and 1 atm. They were both more active than industrial Cr-Fe based catalysts. Rh(0.6%)/La2O3 was the most active but it progressively ...

A Constituição Federal do Brasil determina que o incentivo ao desenvolvimento tecnológico é política indispensável ao desenvolvimento nacional. O objetivo deste estudo é explicar relações entre os investimentos em Pesquisa ...
The Distribution of Base Metals and Platinum-Group Elements in Magnetitite and Its Host Rocks in the Rio Jacaré Intrusion, Northeastern Brazil
(Brasil, 2005)
Anomalously high Pt and Pd values have been found in three magnetite bodies in the Rio Jacaré intrusion of northeastern Brazil. The intrusion hosting these magnetite bodies consists predominantly of pyroxenite and gabbro. ...
Raman studies of Rh and Pt on La2O3 catalysts used in a membrane reactor for hydrogen production
(Elsevier Science, 2004-05)
Rh and Pt catalysts supported on lanthanum oxide were prepared by wet impregnation. The solids were used in a Pd-Ag membrane reactor to produce hydrogen through the carbon dioxide reforming of methane. The effect of the ...
