North America.. In the United States, lignite deposits are located in the northern Great Plains and in the Gulf states. Subbituminous coal is found along the Rocky Mountains. The western half of North Dakota has about 74% of the nation s resources, Montana 23%, Texas 2%, and Alabama and South Dakota about 0.5% each. The lignite resources to 914 m represent 28% of the total toimage of all coal deposits in the United States. The lower cost and low sulfur content have contributed to rapid growth in production.

Note All gasifier effluents are based on Illinois No. 6, except the Winkler, which is based on a Texas Lignite, and the Destec, which is based on an Appalachian Bituminous.

Liquid sulfur dioxide was used to separate the liquefaction products from Texas lignite when Tetralin had been used as the hydrogen donor solvent. The large excess of Tetralin present with the lignite liquefaction products did not interfere with the liquid sulfur dioxide separation procedure. The chemical composition of the fractions were similar to that of SRC and SRL.

There are two ashes (KA and EA) on which none of the five PAHs exhibits detectable photoreactivity, and a third ash (IL) on which none of the PAHs examined thus far (excluding BaA) exhibits detect4-able photodecomposition. At the other extreme, all five PAHs undergo appreciable phototransformation when adsorbed on two ashes (TX and AR). In fact, for each, greater photochemical reactivity is observed on the Texas lignite ash than on any other ash (though less reactivity is observed on the TX ash than on alumina, silica, or glass adsorbents).

The sulfur is relatively easy to remove and the nitrogen is relatively difficult to remove. One of my slides showed that the nitrogen content of products from the Wyoming coal is about the same as from Illinois coal or from the lignite from Texas.

I thank all of the authors for their efforts in preparing a preprint for the symposium and in subsequently revising the preprint into chapter form while accommodating the recommendations of the peer reviewers and the editor. Particular thanks are due to Tom Edgar and Bill Kaiser for preparing the overview chapter on Texas lignite (which was not a paper in the symposium) under forced draft with a very tight schedule.

In this paper we review recently published investigations on Texas lignite dealing with the above subjects, summarizing the key results, and make some assessments about its future utilization potential.
