## Chromatographic behaviour of 64 pure hydrocarbons and nitrogen compounds was verified by gel permeation chromatography. It was found that the elution volumes of almost all nitrogen compounds were higher than the elution volumes of aromatic hydrocarbons. This knowledge was used in the separatio

This paper describes the design and use of a tester developed to enable rapid-assessment of the handling characteristics of a coal, which is of importance for the smooth operation of a coal handling plant. The Edinburgh Cohesion Tester is for use of uniaxial unconfined compression of bulk solids. It
