Abstract
alm tree trimmings represent primary landscaping residue in the United Arab Emirates, making it an easily accessible feedstock for bio-based products generation. This study examines organosolv treatment of the palm fronds as a method of delignification and fractionation of this lignocellulosic biomass. The results revealed that treating palm fronds with ethanol-water mixture at elevated temperature (200oC) results in up to 43% lignin recovery with no catalyst added. This corresponds to production of 13 g lignin per 100 g raw dry biomass. Over 90% glucan was found to be retained in the solid fiber fraction after the treatment, producing cellulose-rich pulp.
