Hiawatha coal

The exinites isolated from PSOC-106, 828, and 1103 are relatively rich in sporinite, Table II. For comparison, we examined the resinite isolated from a Hiawatha coal. The exchange datum for this pure maceral, Table III, indicates that it is a significantly less effective agent for the promotion of the exchange reaction than the sporinite-rich macerals isolated from the other samples in spite of the fact that the whole Hiawatha coal is more reactive than the other whole coals.

Similar runs were made under the same conditions using air as the carrier gas. The percent weight loss for the He and air runs are compared in Table IV. The TGA-MS-C results for Hiawatha coal summarized in Figure 5 is an example of the type of effluent to expect from this kind of... 

Figure 15 shows isometric maps of Loveridge and Hiawatha coals and Noonan lignite. Shown on these maps are the mass chromatograms of m/e 191 and 206, and the molecular ions masses corresponding to the C27, C28, C29, C30, and C31 pentacyclic triterpanes. 

Figure 16 is a 30-degree isometric cap of all the data acquired in a py-GC-MS run of a Hiawatha coal sample. This figure serves to give an...

Samples. Two of the coals used 1n this study were obtained from the Penn State Coal Sample Bank, an HVA bituminous coal (PSOC 1103) from the Upper Elkhorn 3 seam in Eastern Kentucky and an HVA bituminous coal (PSOC 828) from the Brazil Block seam in Indiana. A third coal from which vitrinite and fusinite were hand picked was an Illinois No. 2 seam HVC bituminous coal from Northern Illinois. Also, resinite and vitrinite samples were hand picked from a Hiawatha seam bituminous coal from the King 6 mine in Utah. Finally, the alginite sample was obtained from an Ohio No. 5 seam (PSOC-297) coal by 06C (2,5). All of the elemental and petrographic analyses are presented in Table I. The details of the sink-float technique have been reported previously (1). Typically, a 3 micron particle size demineralized coal Ts centrifuged in aqueous CsCl2 solution of the appropriate density with a small amount of surfactant added to disperse the coal particles. The exinites in the float are... 

Hiawatha King 6 whole coal contained 9.5% ash, Illinois No. 2 vitrinite contained 3.1% ash, and Illinois No. 2 demineralized fusinite contained 4.0% ash. All the other samples contained less than 1% ash. 

The hydrogen atom exchange reactions between Tetralin and diphenylmethane and the reduction of the ketones were studied in the presence of a selected group of raw whole coals, demineralized whole coals, and demineralized macerals. The macerals used in this work were obtained from two hvA bituminous coals, one from the Kentucky Upper Elkhorn No. 3 Seam (PSOC-1103) and one from the Ohio Lower Kittaning No. 5 Seam (PSOC-297) two hvB bituminous coals, one from the Indiana No. 1 Block Seam (PSOC-106) and one from the Hiawatha King 6 Mine and two hvC bituminous coals, one from the Illinois No. 2 Seam and one from the Indiana Brazil Block Seam (PSOC-828). 

The CnH2n-i2 shows an increase in relative concentration of naphthalenes going from the Noonan lignite to the Loveridge coal. Cadalene was identified only in the Noonan, Wyodak, and Hiawatha samples. Bendoritas (5) first identified cadalene in three crudes from the Jackson Sands formation in Texas. He suggested naturally occurring cadinene as a possible precursor. 

Figure 11 shows orthogonal maps of only the Noonan, Hiawatha, and Loveridge coals. This map shows the CnH2 -2 components, including the dialkenes or monocyclic alkene-type components which appear to... 

Heavy Oil Preparation and Separation. Hydrogenation of Hiawatha, Utah, coal [C 72.0 H 5.6 N 1.7 S 0.90 O 19.8 dry, ash-free (DAF) %] was performed at a reaction temperature of 510°C and 12.4-MPa hydrogen pressure with ZnCl2 impregnated on the coal as catalyst in an entrained-flow, tubular coil reactor (10). The reaction products were trapped in three reservoirs connected to the reactor in series and were separated according to their condensability. Heavy-oil products collected in the first reservoir, nearest to the reactor, were used in this study.
