Solid fuels (derived so/id fuels) 97lO1705 Concentration and extraction of inclole in coke production Zaretskii. M. I. cr ul. K&s K/tint., 1996, (7), 17-20. (In Russian) This paper presents a two-stage process for indole concentration from absorption oil in coke production. It allows the production of indole and mcthylindoles at lower cost than in the production of indole alone. 97101706 Effect of reaction conditions on molten-caustic leaching of oil-sand coke residues Ityokumhul, M. T. and Kasperski, K. L. Trrrt1s. sot. Mir1 . . Mercrll., Exph.. 1995. (Puh. lYY6). 298, 205-209iSection 3. In this paper. the effect of reaction conditions on the desulfurization of oilsand coke residues is detailed. The variables investigated were temperature. reaction time, heat-transfer resistance and mode of caustic soda addition The results show that oil-sand coke desulfurization increases with temperature. reaction time and heat-transfer rate. In an oxidative environment. coke combustion during molten-caustic leaching commences at temperatures ahove 500ยฐC. The mode of caustic addition has no effect on coke desulfurization. 97101707 Effects of preheating and highly heat-conductive brick on coke quality Fukuda. K. and Arima. T. /+o~~. Anrllr. lnf. fittshurgh Cm/ Cmf., 1995, 12. 887-802. A study of the effect of preheated coal charging method on the coke quality, especially the coke size. 97101706 Improving quality monitoring of coal and its products Onishchenko. A. M. and Ciorlov, Y. I. Kohs Khim.. 1996. (7), 5-8. (In Russian) The authors consider the improvement in the accuracy of online monitoring of coking coal and coke by increasing the types of signals and parameters used. The one-dimensional distribution of the signals according to the seventh type from the set of Pearson continuous distributions is considered from this viewpoint.
