• CO2 methanation over Ni-Al LDH-derived catalyst with variable Ni/Al ratio 

      Dias, Yan Resing; Pérez Lopez, Oscar William (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 

      Lima, Dirléia dos Santos; Pérez Lopez, Oscar William (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 

      Espindola, Juliana da Silveira; Gilbert, Christopher J.; Pérez Lopez, Oscar William; Trierweiler, Jorge Otávio; Huber, George Willis (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 

      Souza, Guilherme de; Marcilio, Nilson Romeu; Pérez Lopez, Oscar William (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 ...
