Pulsation fluidized bed (PFB) has indisputable advantages for the dry coal beneficiation process. Due to the interaction mechanism between pulsation gas flow and particles is not clear, the regulation of the parameters is still based on empirical method. In this study, the oscillation characteristics of PFB in relation to pressure fluctuations and ...

In this study, a micro fluidized bed reactor analyzer (MFBRA) was adopted to test the isothermal reaction characteristics of tar catalytic reforming by char and thermal cracking by quartz sand from 1023 to 1223 K. The behaviors of tar conversion, the evolution of gaseous products generation, and the corresponding reaction kinetics were comprehensiv...

We present a visualized measurement of the transient Marangoni effect occurring in interfacial mass transfer processes by using a planner laser-induced fluorescence (PLIF) technique. Since acidity increased remarkably and linearly the fluorescent intensity of Rhodamine B, the concentration distribution of acidic solute inside a drop was obtained by...
The impaction of a single fly ash particle with a powdery layer consisting of uniform fine particles is numerically studied by means of the discrete element method. The influences of the incident velocity and the packed particle size on the microstructure of the powdery layer as well as the impact crater are systematically investigated. It is found...

Weak n-type characteristics or poor p-type characteristics are limiting the applications of binary semiconductors based on ambipolar field-effect transistors (FETs). In this work, a ternary alloy of In0.2Ga0.8As nanowires (NWs) is successfully prepared using a Ni catalyst during a typical solid-source chemical-vapor-deposition process to balance th...
Metallic hydride clusters have greater importance due to its unique physicomechanical properties. For solid-state hydrogen storage, (HfH2)(n) clusters has been considered a promising candidate because of high hydrogen capacity, low cost and larger interacting affinity between atoms. The structural and electronic properties of (HfH2)(n), clusters ar...
