Abstract
The chemical structure of product oils and recycle solvents derived from the solvent-recycle liquefaction experiment of Taiheiyo coal was studied by means of “molecular-ion-spectrum method” utilizing FI mass spectrometry. Hydrogenated anthracene oil, used as a starting solvent, is mainly composed of aromatic hydrocarbons of two to four rings. Hydrogen donating compounds contained in the hydrogenated anthracene oil, such as dihydrophenanthrene, tetrahydropyrene, hydrogenated acridines etc., were quickly dehydrogenated in the early stage of recycling. Acidic oil, saturate oil and polar oil were integrated in the recycle solvent by each recycle run, but their compositions did not show a marked change with recycling.
