Photohydrogenation of Aerocolloidal Coal Dust. Final Report,January 1, 1976--May 15, 1977.

摘要

A photo-reactor capable of generating approximately 10exp 13hydrogen atoms/cc has been designed and partially tested in the temperature range 25exp 0 C to 250exp 0 C. Photoproduced hydrogen atoms yielded virtually no volatile products from Illinois No. 6coal, -50/+38micrometers in size,at ambient temperatures but considerable C sub 2 - C sub 8hydrocarbons near 200exp 0 C. Pittsburgh HiSeam and Utah-Emery coal gave similar results but sub-bituminous Wyoming-Wyodak was unreactive. Progress in studying the hydrogen atom -coal dust interaction by T.O.F. mass spectrometry is described. The T.O.F. mass spectrometer has been interfaced with the gas chromatographs for photo-product identification and is ready for use. Ancillary research on solvent extractive quenching of flash-heated coal is reported and slurry-stability implications are discussed. Two appended reports have been entered individually into EDB and ERA. (ERA citation 03:038795)
