The aim of this work is to address the activation process of a high temperature shift (HTS) catalyst, composed of Fe2O3/Cr2O3/CuO, by analyzing it before activation (HTS-V) and after activation (HTS-A) using complementary ...

Chromium-doped magnetite is the traditional catalyst used in the high temperature shift reaction in industrial processes. This work reports a method for preparing this solid, by heating chromium-doped iron(III)hydroxoacetates ...

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 water gas shift reaction (WGSR) has been extensively used in industrial processes, being a fundamental step for the commercial production of high purity hydrogen over the years. For economical purposes, the reaction ...

Copper and chromium-doped magnetite was prepared to be used as catalysts, in the active phase, in the high temperature shift (HTS) reaction. Samples were produced by heating a mixed hydrate ferric oxyhydroxide (IHA) in the ...

Considerando a busca por tecnologias mais limpas e sustentáveis, o hidrogênio surge como uma das fontes de energia mais práticas e sustentáveis do futuro. Esse combustível é obtido comercialmente pela reforma de gás natural, ...
