Gas-solid phase reaction The invention relates to a process and reactor for the quasi-continuous performance of a chemical reaction on the surface of a fixed reactant in a gas/solid phase reaction. In particular, the invention relates to a thermal process and a ... M Roeb,C Sattler,R Kl...
The gas- solid two-phase flows of the precalciner were simulated by different multiphase models, such as mixture model, the Eulerian model, including mixture and dispersed, and discrete phase model (DPM). The results of the different multiphase models were analyzed and compared, showing the ratio...
The gas/liquid phase turns into three-phase flow system (gas-liquid-solid) in the pipeline as hydrates form continuously and begin to deposit on the pipe wall. At low temperature and high-pressure conditions, hydrate particles will therefore exist in the liquid film and the liquid droplet as ...

Employing 1 H and 2 H gas phase NMR the kinetics of simple catalytic model reactions is studied. Employing 2 H-NMR solid state NMR spectroscopy, the interaction of the metal surface with the substrate is characterized and kinetic data, which characterize the mobility of the deuterium on the ...
Delivery devices for delivering solid precursor compounds in the vapor phase to reactors are provided. Such devices include a precursor composition of a solid precursor compound with a layer of packing material disposed thereon. Also pro... DV Shenai-Khatkhate,Timmons, Michael L,Marsman, Charles ...
Mass spectrometry is a powerful technique for the structural and functional characterization of biomolecules. However, it remains challenging to accurately gauge the gas-phase structure of biomolecular ions and assess to what extent native-like structure
shock wave; gas–solid two-phase flow; drag force; annular vortex; entrainment effect1. Introduction The gas–solid two-phase flow resulting from interactions between a shock wave and solid particles is highly complex and difficult to observe experimentally [1,2]. However, workable knowledge ...
There were however no published experimental data at the time to validate their calculations. The effect of particle size on solid- as well as gas-phase motions in vertical and horizontal two-phase flows has been extensively studied in the literature. With the aid of a laser-Doppler velocimeter...
