Estudio de la dinámica sedimentaria de la Laguna costera del Sur de Túnez (Túnez, Mar Mediterráneo)
La laguna sur de Túnez, una laguna costera mediterránea poco profunda, se sometió a importantes trabajos de restauración durante el período 1998-2001, lo que ha llevado a cambios estructurales y funcionales de este ecosistema costero.

Desulfurization in the FCC riser is achieved by modifying zeolite catalysts with La3+ ions, promoting H2S formation from thiophenic compounds while suppressing secondary reactions. This approach enhances gasoline quality by increasing selectivity for H2S and enabling efficient condensation and alkylation, supporting cleaner fuel production and ...

Abstract This paper presents a novel technology for converting glycerol, a byproduct of the biodiesel industry, into glycerol carbonate, a high‐value bioproduct. The effect of calcination temperature on the synthesis of quaternary Cu‐Ni‐Mg‐Al catalysts (MMO‐Cu15Ni15‐Tz) and their application in the transesterification reaction was investigated ...

Catalysts with varying palladium (Pd) loading supported on activated carbon were assessed for their effectiveness in the oxidative condensation of furfural. Furan‐2‐acrolein was the primary product, depending on the palladium content. Reusability tests showed a decline in the yield of furan‐2‐acrolein.

The electronic modulation of Nb‐doped Co3O4 catalyst showcases enhanced activity and extended stability for OER in both alkaline (1M KOH) and acidic (0.5M H2SO4) electrolytes. The higher activity emanated from the synergistic effect between the Nb5+ dopant and Co3O4.
