Based on a promising process of biomass to liquid (BTL) fuels, a pilot-scale plant including gasification, direct synthesis of dimethyl ether (DME) and DME to gasoline was developed. The evaluations of the designed facilities and the optimization of the operation parameters for the whole system were carried out. The several running tests demonstrated the feasibility of converting biomass to high octane...
Mesoporous ZSM-5 was synthesized using double-template method and its application in Fischer–Tropsch synthesis (FTS) was studied. By comparison, ZSM-5 and SBA-15 were also prepared. The results demonstrated that the catalysts with bimodal structure and moderate acidity showed higher C5–18 selectivity with relatively lower CH4 selectivity, while higher C5–12 selectivity over Co/ZSM-5 catalyst and higher...
Ni/HZSM-5 catalysts with different Ni contents ranging from 0.76 to 5.05wt.% were prepared by wet impregnation method. The catalysts were characterized by X-ray diffraction (XRD) and N 2 adsorption, diffuse reflectance ultraviolet–visible spectra (UV–vis DRS), X-ray photoelectron spectroscopy (XPS), temperature-programmed desorption of ammonia (NH 3 -TPD) and the Fourier transform...
Cu–La 2 O 3 –ZrO 2 /γ-Al 2 O 3 hybrid catalysts were prepared by four different preparation methods. The catalysts were characterized by N 2 adsorption and desorption, N 2 O adsorption, X-ray diffraction (XRD), temperature programmed reduction (H 2 -TPR), temperature programmed desorption (NH 3 –TPD) and Fourier transform infrared...
