主 题：Salicornia bigelovii Bio-oil Hydrodeoxygenation Catalytic upgrading Transportation fuel Reaction mechanism
摘 要：Because of socioeconomic considerations,wide-scale production of biofuel necessitates the utilization of nonedible biomass feedstock that does not compete for land and fresh water *** this regard,Salicornia bigelovii(SB)is the most investigated halophyte *** high oil content in SB seeds has sparked mounting research that aims to utilize SB as an industrial crop in the production of bio-oil,particularly in coastal areas where these plants ***,the oil extracted from the pyrolysis of raw SB seeds is largely dominated by oxygenated fatty acids,most notably 9,12-octadecadienoic acid and 9,17-octadecadienal,typical to that of other *** pyrolysate bio-oil of the raw SB seeds exhibited a relative yield of oxygenated compounds that decreased from 57.05%at 200℃to 9.81%at 500℃,and the relative yield of nitrogenated compounds increased from 4.86%at 200℃to 21.97%at 500℃.To improve the quality of the produced bio-oil,herein we investigated the catalytic hydrodeoxygenation(HDO)of the fragments that were produced from the thermal degradation of SB seeds.A 5%Ni–CeO_(2)catalyst was prepared and characterized by a wide array of methods X-ray diffraction,X-ray photoelectron spectroscopy,temperature programmed reduction,scanning electron microscope,BrunauerEmmett-Teller analysis,and thermogravimetric *** catalytic run was executed between 200 and 500℃in a flow *** deployed catalytic methodology displayed a profound HDO *** 400℃,for instance,the gas chromatography mass spectroscopy(GC–MS)detected loads of paraffin and aromatic compounds exists at appreciable values of 48.0%and 28.5%,*** a total relative yield of 43.2%(at 400℃),C8–C15 species(i.e.,jet fuel fractions)were the most abundant species in the upgraded SB *** release of H_(2),CO,CO_(2),and CH_(4)was analyzed qualitatively and quantitatively using gas chromatography thermal conductivity detector and Fourier infrared spectroscopic *** the Ni
