WV Coal Member Meeting 2024 1240x200 1 1

Libya and H-Coal


 
We earlier reported on the H-Coal Coal-to-Liquid conversion technology, and it's pilot plant reduction to practice in Kentucky.
 
There are more confirming documents, as we told you, and we await any expression of interest before sending them along.
 
But, we found this one piece to be of special intrigue, and we think, upon review of the author's bona fides, you'll understand why.

Abstract

This Paper deals with a comparative study on the use of gel permeation chromatography (g.p.c.) and vapour pressure osmometry (v.p.o.) to obtain molecular weight data for the hexane-soluble fractions of three H-coal liquids. The use of two types of column packing materials, polyvinylacetate and styrene-divinylbenzene copolymer gels, is described. A successful, preparative use of the polyvinylacetate gel to fractionate the hexane-soluble fraction of H-coal liquid, atmospheric still overhead (ASO), has been established. Molecular weight data obtained by v.p.o. for the benzene-soluble fraction and the pyridine-soluble fraction of the three H-coal liquids are reported. Solvent extraction has been utilized also to find the amount of oil, asphaltenes and asphaltols in the three H-coal liquids.
