      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 ...
