| Popis: | The effects of the gas flow rate in the reactors and the boiling point range of the feed solvent on conversion in brown coal liquefaction were investigated in the presence of iron-sulfur catalyst, using a continuous reactor system. An increase in the gas flow rate (GFR) markedly increased the distillate yield and the distillate/H 2 consumption ratio, converting effectively the heavier fraction derived from the coal. A light feed solvent provided a higher distillate yield than a heavy feed solvent at the same GFR. These results are explained by greater vaporization of lighter solvent fraction to concentrate the heavy fraction and hence to prolong the actual residence time of the latter fraction in the reactor. Analysis of the product and liquid sampled directly from the reactor proved that heavier components were left in the reactor at higher GFR. |
