| Popis: | Catalytic hydroliquefactions (HL) of two coals (Freyming, France and Point of Ayr, United Kingdom) and their macerals were studied in a microautoclave in the presence of an H-donor solvent (tetralin). The main results of the study were related to (i) a comparison between the behaviours of such coals or macerals in the HL process; the two raw coals showed the same total conversion, and similar wt% of oil, asphaltene and preasphaltene fractions, (ii) the contribution of each maceral to the global coal liquid; the additive effect was checked, but no synergetic effect was found (using HL and the present type of liquid phase analysis) for a'synthetic coal'. Raw coals, vitrite and exinite had the same total conversion, whereas that for fusite was much lower, and (iii) a detailed identification of some individual compounds or of series of homologous compounds; this was made for oil fractions |
