Abstract: The present disclosure relates to a process for producing anhydrosugar(s) from lignocellulosic biomass. In particular, the present disclosure relates to a process for producing anhydrosugar(s) from lignocellulosic biomass by pre-treating the lignocellulosic biomass by contacting it to either an acid or an acidic solution to obtain a pretreated lignocellulosic biomass and subjecting the pretreated lignocellulosic biomass to active pyrolysis followed by condensation to obtain the anhydrosugar(s) in high yield. Further, the present disclosure encompasses utilizing the food organic waste, date pits biomass for production of anhydrosugar(s), Levoglucosan in high yield.

Abstract: There is disclosed a highly efficient and economical catalyst for carbon monoxide (CO) oxidation at low temperatures, using a non-noble transition metal composition of copper oxide (CuO), cerium oxide (CeO2), and niobium oxide (Nb2O5). The catalyst, designated as 10CuCeNb, is synthesized via the wet impregnation method and is composed of with 10% CuO—CeO2 supported on Nb2O5. It shows a significantly improved performance with full CO conversion achieved at relatively low temperature of 150° C. It demonstrates high stability over a 12-hour reaction time. The activation energy (Ea) is 23.1 kJ mol?1, supporting low-temperature CO oxidation with minimal energy input. The catalyst's high activity and stability are attributed to the formation of oxygen vacancies and active Lewis acid sites generated from the synergistic interaction between CuO, CeO2, and Nb2O5.

Abstract: There is disclosed a process for debromination of novel brominated flame retardants (NBFRs) through co-pyrolysis with zinc oxide (ZnO) and franklinite (ZnFe2O4) to effectively restrict brominated species emission from NBFRs during thermal degradation. The method addresses environmental concerns by converting tetrabromobisphenol A 2,3-dibromopropyl ether (TBBPA-DBPE) and tetrabromobisphenol A diallyl ether (TBBPA-DAE) into bromine-free hydrocarbons. Utilizing Zn-based metal oxides from electrical arc furnace dust (EAFD), this process transforms them into metal bromides, facilitating selective zinc extraction. Thermogravimetric analysis guides pyrolysis at up to 500° C., revealing ZnO's efficacy in capturing ˜92% of HBr gas and producing minimal brominated compounds (relative area, 0.83%). Phenol emerges as a significant condensable product, while inorganic gases and methane dominates the non-condensable fraction.
