To utilize the coal direct liquefaction residue (DLR) and improve the tar yield and quality, experimental studies on co-pyrolysis of lignite and DLR were conducted with a fixed-bed reactor under atmospheric pressure in high purity nitrogen. In-situ micro-Raman experiments, Soxhlet extraction, scanning electron microscope, and X-ray energy spectra analysis were also performed to explore the interaction...
Through the reaction of methane reforming with CO 2 , the influence of calcination temperature on the NiO/MgO catalyst prepared by impregnation was investigated. Results indicated that the NiO/MgO catalyst torrefied at 800°C displayed stronger interactions between metal and support, and also exhibited higher activity. In order to provide further insight into the adsorption and hydrogenated...
The direct synthesis of gasoline-range iso-paraffins from synthesis gas (CO+H 2 , syngas) via modified Fischer–Tropsch (FT) reaction was investigated in the slurry phase reaction system, the contact state of hybrid catalyst components and the composition of hybrid catalyst were optimized in this reaction system. The results show that the FT reaction and the in situ hydroconversion of its products...
Catalytic performance of several bifunctional cobalt-based catalysts in slurry-phase Fischer–Tropsch synthesis has been investigated at 1MPa and 230°C. The catalysts were prepared according to the conventional impregnation method using SiO 2 , Al 2 O 3 , montmorillonite (K10 ® ), and various zeolites (USY, ZSM-5 and MCM-22) as a support. When an acidic support was applied,...
