| dc.description.abstract | Lignocellulosic biomass has a great potential for biofuel and fine chemical productions. This study focused on the effective conversion of the lignocellulosic biomasses, particularly sugarcane bagasse to the most valuable aromatic hydrocarbon called Para-xylene via two-step acid-catalyzed hydrolysis, dehydration, hydrogenation, and Diels-Alder cycloaddition reaction steps. Para-xylene is one of the most important aromatic hydrocarbons, which is used for the production of purified polyethylene terephthalate (PET), in which it is used for the production of world plastics. So, the production of fine chemicals from biomass helps to reduce the dependence of the imported oils as well as used to improve the overall economic and sustainability of the world. In this study, the effect of operating variables on the Diels-Alder cycloaddition reaction between the biomass-derived furan and the suitable dienophile, which is called Maleic anhydride, was investigated and optimized using the most reactive and selective Lewis acid catalyst (AlCl 3 ). In the Diels Alder cycloaddition reaction, the effects of reactant molar ratio, catalyst loading and reaction time on the conversion of DMF and the yield of dimethyl benzoic acid was investigated and optimized using Design expert®7 software. As the result, 41.4% conversion of DMF and 64.6% yield of dimethyl benzoic acid were obtained at the optimum values of the operating variables such as molar ratio of the reactant, catalyst loading and reaction time. And also, the effects of acid concentration and reaction time on the dehydration of dimethyl benzoic acid to Para-xylene were investigated, and 70.36% conversion of dimethyl benzoic acid and 49.66% yield of Para-xylene were obtained. In addition to this, the final product (Para-xylene) was analyzed using FTIR and GC-MS. As the result, the FTIR result is the same with the standard functional group of 1,4-dimethyl benzene, and 30.88% composition of Para-xylene were obtained using GC-MS. | en_US |
