Phase equilibrium in coal liquefaction processes

Phase equilibrium in coal liquefaction processes. Final report. Chao, K. C. (Sch. Chem. Eng., Purdue Univ., Lafayette, IN, USA). Report, EPRI-AP-3450; Order No. TI84920508. 206 pp. Avail. RRC, Box 50490, Palo Alto, CA 94303 From: Energy Res. Abstr. 1984, 9(21), Abstr. No. 42594 (English) 1984. DOCUMENT TYPE: Report CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Section cross-reference(s): 69 Gas-liq. equil. data were detd. in simulation of coal liquefaction process conditions in mixts. of light gases and heavy hydrocarbons. The mixt. systems newly investigated are: CH4 [74-82-8]-9,10-dihydrophenanthrene [776-35-2]; H-CH4-1-methylnaphthalene [90-12-0]; H-CO2-Tetralin [119-64-2], H-CO2-1-methylnaphthalene; H-CO2-quinoline [91-22-5]; N-Tetralin, -n-hexadecane [544-76-3], -1-methylnaphthalene, -quinoline, and -m-cresol [108-39-4]. Correlations for the solubilities of CH4 and CO2 were developed from the data based on the use of soly. parameters. Two equations of state are developed for the description of both the gas soly. and the vaporization of the heavy oil. The Chain-of-Rotators (COR) equation of state explicitly accounts for the rotational mol. motion contribution to the pressure of a fluid. The Cubic-Chain-of-Rotators (CCOR) equation is obtained upon simplifying the COR equation. Interaction consts. in the CCOR equation were detd. for the light gases with the heavy hydrocarbons based on data from this project, and the consts. are correlated. Equil. flash vaporization was exptl. detd. for 3 coal liqs. and for their mixts. with H. The data are correlated with the CCOR equation of state.

The relative effectiveness of aromatic solvents in the liquefaction of brown coal and bituminous coal

The relative effectiveness of aromatic solvents in the liquefaction of brown coal and bituminous coal. Kamiya, Y.; Nagae, S.; Yao, T. (Fac. Eng., Univ. Tokyo, Tokyo 113, Japan). Proc. - Int. Conf. Coal Sci., 184-7. Cent. Conf. Manage.: Pittsburgh, Pa. (English) 1983. CODEN: 53NIA5. DOCUMENT TYPE: Conference CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Section cross-reference(s): 25 The reactivities of H-donor solvents used in coal liquefaction were evaluated in ref. to Tetralin (I) [119-64-2], a std. donor solvent. The activity of strong H-donor solvents increased in the following order: I < 1,2,3,4,5,6,7,8-octahydroanthracene [1079-71-6] < 1,2,3,4-tetrahydro-6-naphthol [1125-78-6] < 1,2,3,4-tetrahydroquinoline [635-46-1] < n9,10-dihydrophenanthrene (II) [776-35-2] < 9,10-dihydroanthracene (III) [613-31-0]. Solvents weaker than I include acenaphthene [83-32-9], Decalin [91-17-8], 1-methylnaphthalene [90-12-0], pyrene [129-00-0], indan [496-11-7], and fluorene [86-73-7]. II and III were ~12 times as reactive as I in coal liquefaction but ~4 times as reactive toward free radicals (produced the in-situ thermal cracking of PhCH2OPh [946-80-5] and PhCH2CO2CH2Ph [102-16-9]).
