Abstract Coal-water fuel is a promising substitution of conventional fossil fuels for the countries, where clean energy sources like wind, solar, etc. cannot cover energy demand. However, this fuel has a lot of specifics for preparation, transportation, and combustion. Issues with coal-water fuel combustion can be solved with the use of fuel activation. The catalytic activation of the coal-water fuel produced from coal of different metamorphic stages with the help of titanium dioxide nanoparticl...

Abstract Investigation of the release behaviors of alkali and alkaline earth metals is necessary to understand the mechanisms of ash-related problems such as fouling, slagging, and corrosion when burning fuel with high alkali contents. Using a 2-D circulating fluidized bed (CFB) combustion model combined with a sodium migration model, sodium transformation was predicted in a 30 kW CFB combustor. Simulation results from the 2-D model are in agreement with those from the 3-D model and experiments....

Abstract Trace elements (TE) occur in natural and waste wood in a broad variety at considerable concentrations. Those TEs end up in different ash fractions (bottom-, fine-, and fly ashes) after combustion in furnaces at heat and power plants (HPP). The ash fractions differ significantly in TE concentrations and are therefore of variable quality. On the one hand they can be a matter of cost intensive disposal due to their toxicity. On the other hand they are a resource of valuable elements demand...

Abstract The direct conversion of bamboo to aromatics was investigated over Zn and/or Ga modified zeolite catalysts under a methane environment. Aromatics are the main liquid products from bamboo conversion on a batch reactor. The reaction over Zn-Ga/ZSM5(30) gives 19.2 wt% yield of aromatics with 55.6% selectivity towards BTEX (benzene, toluene, ethylbenzene, and xylene) at 400 °C. Zn loading promotes the deoxygenation of oxygenated intermediates from bamboo decomposition and favors the formati...

Abstract Currently, alternative energy sources such as hydrogen and alcohol are increasingly used in IC engines. There is a gap in the literature of both experimental and numerical studies considering hydrogen addition in a high compression ratio engine (using methanol/hydrogen, ethanol/hydrogen and methane/hydrogen blends). Therefore, in this study, the combustion and emission performance analysis of methanol, ethanol and methane with different hydrogen volume ratios were carried out. The resul...

Abstract Based on high-temperature and low-oxygen diffusion clean combustion technology, a novel-type of heat flue in a coke oven was designed in this paper. By changing the internal structure of the flue and the supply mode of the combustion-supporting gas, fuel zoning and diffusion combustion in the heat flue are achieved. The combustion temperature in the flue and the formation of thermal NOx are greatly reduced. The flow, temperature and NOx concentration fields inside the flue are studied t...

Abstract A zeolite X synthesized from waste fly ashes from the energy sector was used as support in the preparation of Ni-catalysts for CO2 methanation. The catalysts were characterized by XRD, H2-TPR, CO2-TPD and low-temperature nitrogen sorption techniques. At 450 °C CO2 conversions of around 50% were obtained, which are slightly under the range of conversions previously reported for similar Ni-catalysts prepared using commercial zeolites. The non-complete reduction of the Ni-phase, as a conse...

Abstract Five MFI-type zeolite catalysts, which were aluminosilicate ZSM-5 (Z5), gallium-substituted silicalite-1 (Ga-S1), mesoporous ZSM-5 (MZ5), gallium-substituted mesoporous silicalite-1 (Ga-MS1) and gallium-substituted mesoporous ZSM-5 (Ga-MZ5), were hydrothermally synthesized with combined using of TPAOH and TPOAC as micropore and mesopore structure-directing agents respectively, followed by the application in the catalytic upgrading of volatiles from low-rank coal fast pyrolysis. The obta...

The combustion characteristics of mixed municipal solid waste (MMSW) play a vital role in dictating the efficiency of the incineration process. At present, few studies have been reported on combustion characteristics of three components MMSW and the establishment of a corresponding comprehensive kinetic model of single component waste. In the present study, based on the law of mass action and Badzioch's relation, the mathematical expressions for describing the thermogravimetric (TG) curves and t...

Abstract This study developed a platform for determination of the predictive index for outbursts by simulating the field working face of coal roadway and a system for determining briquetting pressures of coal briquettes. Taking a predictive index called the 'initial gas emission from a borehole' (IGEB) as an example, this research carried out the test for measuring this index in the laboratory and determined its critical value for outburst risk in the 31,011 working face in Xinyuan Coal Mine, Sh...
