Multicomponent Ni-CeO2 nanocatalysts for syngas production from CO2/CH4 mixtures
(Elsevier, 2018)
The dry reforming of methane with CO2 is a common route to transform CO2/CH4 mixtures into added value syngas. Ni based catalysts are highly active for this goal but suffer from deactivation, as such promoters need to be ...

Phosphate-type supports for the design of WGS catalysts
(Elsevier, 2018)
The importance of water availability during the WGS reaction has been extensively reported. Thus, the search of new supports able to interact with the water molecule is of great importance. In this work, a series of ...

Influence of the preparation method in the metal-support interaction and reducibility of Ni-Mg-Al based catalysts for methane steam reforming
(Elsevier, 2019)
Ni-Mg-Al based catalysts were prepared using different preparation methods (impregnation, impregnation-coprecipitation and coprecipitation) and tested in steam reforming of methane. The differences observed in catalytic ...

Tailoring structured WGS catalysts: Impact of multilayered concept on the water surface interactions
(Elsevier, 2018)
A novel multilayer approach for designing structured WGS catalyst is employed in this study as a response to the lack of new strategies in the literature. The approach proposes the use of two successive layers with ...

Colombian metallurgical coke as catalysts support of the direct coal liquefaction
(Elsevier, 2019)
A Colombian metallurgical coke was modified in its surface chemistry and was used as support of iron sulfide catalysts for direct coal liquefaction. The modification was made by treatments with diluted oxygen and HNO3 at ...
