Production of light olefins by catalytic conversion of lignocellulosic biomass with HZSM-5 zeolite impregnated with 6wt.% lanthanum

Production of gasoline fraction from bio-oil under atmospheric conditions by an integrated catalytic transformation process

“…They proved that the feeds with higher H/C ratios favored to increase the yield of light olefins and reduce the coke. Our recent study also shows that light olefins can be selectively produced from bio-oil or biomass over the La-modified zeolites [8,28]. Furthermore, catalytic polymerization of light olefins has been industrially applied in petroleum refineries for producing fuels, and the synthesis fuels using olefins oligomerization could be suitable for utilization as engine fuels due to free of sulfur and other harmful impurities [29e35].…”

Effect of Zn/ZSM-5 and FePO4Catalysts on Cellulose Pyrolysis

“…The zeolite catalysts containing transition metal oxides afford some special catalytic properties, such as olefin aromatization and oxidation-reduction, which the parent zeolite catalysts do not have, by incorporating some transition metal ions such as Ga, La, and Fe into the zeolite framework or channel [23][24][25][26][27][28]. The zeolite catalysts containing transition metal oxides have been widely used in petroleum refinery industry, N 2 O direct decomposition, NO removal, and selective oxidation [26,29].…”

One-pot aqueous phase catalytic conversion of sorbitol to gasoline over nickel catalyst

“…2. The peaks at 2h of 7.9°, 8.7°, 23.0°and 23.9°were attributed to the ZSM-5 zeolite crystal structure [10,38]. For Ni/HZSM-5 catalyst, the ZSM-5 characteristic peak intensity decreased obviously.…”

“…The acid characterization of tested catalysts with NH 3 -TPD gave an estimation of the acid sites amount and strength. The peaks at 423-523 K were assigned to the desorption of NH 3 from the weak acid sites and the peaks at 623-823 K were corresponded to the desorption of NH 3 from the strong acid sites [10,19]. As shown in Fig.…”

“…Biomass is currently the most abundant and inexpensive renewable alternative energy resources [5][6][7][8]. Biomass-derived sugar alcohol sorbitol has been reported as one of the ten platform compounds by the U.S. department of energy (DOE) [9,10]. In addition, it is easily obtained by hydrogenation of glucose or direct degradation/hydrogenation of cellulose, low thermal stability and natural hydrophility due to its high oxygen content with six hydroxyl groups [11,12].…”
