Capillary Structure of Coals

Abstract

A CONFERENCE on the “Ultrafine Structure of Coals and Cokes”¹ was held in London in 1943 ; later, Bangham et al. ² proposed a model for coals in which the capillary system was located between closely compacted spherical ‘micelles’. More recently, in the laboratories of the British Coal Utilisation Research Association, an extensive investigation of the adsorptive properties of some British coals has been carried out, and has led to a new model of the physical structure of coal. This model may be described briefly as follows.
