CO2 methanation over Ni-Al LDH-derived catalyst with variable Ni/Al ratio
(2023) [Artigo de periódico]CO2 methanation is a promising technology to recycle CO2 into useful chemicals, fuels, and energy, avoiding its emissions in the atmosphere, as well as for the purification of H2 streams containing CO2. In this work, Ni-Al ... -
Conversão catalítica do etanol sobre catalisadores suportados em ZSM-5
(2018) [Artigo de periódico]O petróleo, fonte de energia não renovável, é a principal matéria-prima usada na produção de derivados como combustíveis, lubrificantes e petroquímicos básicos. Neste contexto o etanol, uma matéria-prima renovável, torna-se ... -
Conversion of furan over gallium and zinc promoted ZSM-5 : the effect of metal and acid sites
(2020) [Artigo de periódico]The addition of gallium or zinc to ZSM-5 increases the aromatic selectivity and decreases the olefin selectivity for furan conversion. Both the benzene and naphthalenes selectivities increase with small amounts of gallium ... -
Dry reforming of methane at moderate temperatures over modified Co-Al Co-precipitated catalysts
(2014) [Artigo de periódico]M-Co-Al (M = Ca, La, Li or Mg) materials were synthesised by co-precipitation and investigated for dry reforming of methane. Thermogravimetry, temperature-programmed oxidation, reduction and CO2 desorption, specific area ... -
A new non-complex synthesis of NiO nanofoams for hydrogen storage applications
(2023) [Artigo de periódico]The use of nanofoams is beneficial for a wide range of applications ranging from catalysis to plasmonics. The present communication reports on the non-complex synthesis of NiO nanofoams and their use for hydrogen storage ... -
Removal of reactive red 120 on Fe-hydrotalcite : isotherms study
(2019) [Artigo de periódico]HDL-MgFe is a Hydrotalcite that represent a compound lamellar double hydroxide. It was prepared through the continuous co-preparation method. The solid was characterized by surface area measurements, X-ray diffraction and ...
