Evaluation of thermal pyrolysis characteristics and kinetic parameters of cellulose extracted from date waste using natural deep eutectic solvent
Natural deep eutectic solvent (NADES) composed of choline chloride and formic acid was used to fractionate date waste into lignin and cellulose streams. NADES treatment increased the cellulose content from 44 wt% in raw waste (RW) to 72 wt% in extracted cellulose fibers (CFs). Scanning electron…

Advances in dry reforming of methane to syn gas production: MOF-derived materials as efficient catalysts
Dry reforming of methane (DRM) is an attractive route for the simultaneous valorization of two greenhouse gases, CH4 and CO2, into syngas (H2/CO), a key intermediate for fuels and value-added chemicals. However, the practical application of DRM remains limited by catalyst deactivation, mainly…
