The minerals present in lignite were postulated to catalyze the liquefaction. The relative sources of CO was important because it suggested the economics of using a synthesis gas over hydrogen during liquefaction. For the three sulfur compounds, hydrogen is superior to carbon monoxide--water for desulfurization. The CO--H/sub 2/O results were accounted for by the reduction caused by hydrogen from the shift reaction. Since benzoic acid was formed in the reactions of diphenylsulfide and thioanisole only when carbon monoxide was present, it must have been the source of the carboxyl group directly or indirectly. In the diphenylsulfide reductions, carbon monoxide was the source of the methyl group of toluene. The added materials, tetralin, Na/sub 2/CO/sub 3/ and FeS, exhibit the diphenylsulfide and thioanisole reduction conversions and have little net effect on the dibenzothiophene reactions. Tetralin was not behaving as a good hydrogen donor, but rather as an inert divalent of the reducing gases. Less than 5% of the tetralin was converted into naphthalene. 3 tables.
