Thermal dissolution (TD) of coal and hydro-liquefaction of the thermal dissolution soluble fraction (TDSF) with a high activity catalyst is one of effective high efficient hydro-liquefaction of coal techniques. In this study, a Chinese Shenfu (SF) sub-bituminous coal was thermally dissolved, and the TDSF obtained was further hydro-liquefied with Ni–Mo-S/Al2O3 catalyst. Based on the hydro-liquefaction...
As the fast depletion of coal resources, exploring the value-added utilization approaches of low rank coals or their components and, in parallel, promoting the conversion of sustainable resources (such as biomass) into useful chemicals are critical issues facing human society. In this work, we used humic acids (HAs), an abundant material in nature (mainly derived from low rank coals), and the transition...
To obtain ultra-deep hydrodesulfurization (HDS) on the fluid catalytic cracking (FCC) gasoline and diesel, a novel catalyst has been prepared by an arc discharge method. This nickel yttrium (Ni–Y) bi-metallic catalyst is attached on single-walled carbon nanotubes (SWCNTs) and it shows higher HDS activities than that of mono-metal catalyst. Our results demonstrate that the content of SWCNTs has important...
Experiments on combustion of methane, methanol, and ethanol in packed bed combustors were performed with the ZSM-5 zeolite supported nanometer-sized Pt as the catalyst. Methane combustion was investigated in the combustors in which the lengths of catalyst beds were 40, 20, and 10mm, respectively. The stabilization and conversion rate of methane combustion were both the highest in the combustor with...
The electrochemical hydrogenation of coal on NiB, polyvinylpyrrolidone (PVP) bond NiB and PVP-NiB/SiO 2 amorphous alloy catalysts was systematically investigated in the alkaline electrolyte. The catalysts were prepared by Watanabe method using borohydride reduction. Structural properties of the catalysts were characterized using XRD, IR, ICP, BET, TEM and XPS techniques. The activity of the...
