Hydrogen was evolved as hydrogen sulphide when coal-derived solvents for liquefaction were heated with sulphur (dehydrogenation method) and their naphthene contents were quantified by titration and 13C n.m.r. analysis to estimate the amount of transferable hydrogen from hydroaromatics present in the

The work reported here represents initial attempts to develop a complete kinetic and mechanistic understanding of the reaction chemistry of H,S under coal liquefaction conditions, using both model systems and coal. Hydrogen sulphide was found to promotejcatalyse the transfer of hydrogen from tetrali
The roles of the vehicle and gaseous hydrogen during short contact time liquefaction (SCTL) in microreactors were examined by using a number of synthetic vehicles. The importance of vehicles during SCTL was evaluated on their ability to convert coal to tetrahydrofuran (THF)-soluble products. Reactio
A series of experiments has been carried out to study the way in which preparation conditions of coal digests influence filtration rate. It was shown that a relation exists between cake resistivity and digestion temperature and time, and therefore good control over digestion conditions is important
