In recent years, Hg re-emission from the wet scrubber has become a hot topic in the field of Hg abatement since wet scrubber has been considered as an effective way to remove Hg. In this paper, the effects of Cu ions on Hg re-emission were investigated for the first time in the presence of SO32−. The effect of CuCl32− was proved to directly reduce Hg2+ to insoluble Hg0 and to catalytically decompose...
Complex interactions among components in the heterogeneous grinding have an influence on breakage and energy consumption characteristics of components in mixtures if compared with the single breakage. In this paper, a modified Hardgrove mill, with the addition of a power meter, is used to simulate the grinding process of vertical spindle pulverizer. Binary-component mixtures of coal and pyrite, or...
In this paper, the effect of calcination conditions on catalytic cracking of toluene over 3Fe8Ni/PG (PG: palygorskite) was investigated. The experimental parameters including the calcination temperature, time and atmosphere and reaction temperature were evaluated. The catalysts were characterized using X-ray diffraction (XRD), H2 temperature-programmed reduction (TPR), transmission electron microcopy...
In this study, the impact of lubricating oil on the nanostructure, composition, and graphitization of diesel particles is studied experimentally. A 4-cylinder turbocharged light-duty diesel engine was used to generate particle samples. In the analysis, high resolution transmission electron microscopy (HRTEM) and thermogravimetric analysis (TGA) were applied to study the nanostructure and the compositions...
In this work, the droplet burning characteristics of neat benzyl azides, diesel-benzyl azides blends (10%, 30%, 50% of benzyl azides (wt.)) and diesel fuel were investigated under atmospheric pressure. The ambient temperature around the flat-flame burner is about 1123K. The initial droplet temperature is about 300K. The effects of ambient oxygen concentration (14%, 21% and 30%) and initial droplet...
Laser ignition of gaseous fuels leads to improved lean-burn combustion, which is a key technology in reducing engine out emissions for meeting stringent future emission legislations. Hydrogen enriched natural gas (HCNG) promotes lean-burn combustion due to higher flammability limits of constituent hydrogen. HCNG is a promising gaseous fuel for spark ignition (SI) engines prior to development and deployment...
