In this paper, we propose a new experimental technique, based on X-ray tomography, allowing the analysis of the gas-liquid-solid phase distribution in trickling flow reactors. Tomography refers to the cross-sectional imaging of an object from data collected by illuminating this object from many directions. The experimental set-up allows the scanning of transverse sections of rather large columns: up to 0.8 m diameter and 2 m height can be irradiated. Experiments were carried out both without and with liquid flow. In the absence of liquid, the reconstructed images give a view of the non-uniformity of the solid phase distribution. The images obtained are very complex because they result from the superposition of several distributions with different Spatial scales. We show the existence of a first spatial scale which allows us to separate properties belonging to the individual packing elements from those belonging to the bed scale. When liquid is flowing through the packed bed X-ray scans give a clear picture of the distribution of the liquid phase saturation, despite the very low liquid film thickness. Average values of this liquid phase saturation are determined and confronted with a partial wetting model. [less ▲]

The article reviews the historical development of processes for the gasification of coal, and discusses the principal chemical reactions employed, describing four principal types of gasifier. It proposes a scheme for combined-cycle generation consisting of a gasifier, gas turbine, heat exchanger/steam generator, and steam turbine. The economics of the scheme are discussed, concluding that although the forecast unit cost of generation is not excessive, the time is not yet ripe for the installation in Belgium of such schemes on a large scale [less ▲]
