Laboratory support for H-Coal Project. Phase III. Monthly progress report No. 69, April 1981. [Reactions in preheater]

Technical Report ·
OSTI ID:6434256
The bench-scale run using the 34-foot-long preheater with coal slurry, but without the reactor, has been completed. In the preheater, under thermal reaction, the coal will undergo several stages of reaction. Whitehurst describes these as: (1) dissolution; (2) hydrogen transfer; and (3) hydrogenation. The purpose of this once-through preheater run is to find out how coal dissolves in the coil preheater; i.e., how coal swells in the solvent and disintegrates. Slurry products coming out of the preheater are analyzed by extraction, defining the product compositions as: oil - pentane soluble; asphaltenes - pentane insoluble/toluene soluble; preasphaltenes - toluene insoluble/THF soluble; and IOM - THF insolubles minus ash in the insolubles. An economic evaluation has been completed on phenol recovery from H-Coal liquids using solvent extraction and HRI's Dynaphen Process. The evaluation concludes that there is an incentive to recover phenol from H-Coal liquids. A complete discussion of the evaluation is included in this monthly report.
