| Summary: | and water were used with toluene. The effects of the aromatic species were predominantly alkylated phenols, benzenes, indenes, pyridines and naphthalenes. At the Big Brown lignite was liquefied in a fixed bed tube reactor. Brown lignite and yield of liquid were increased. Water is coal hydroliquefaction. Further research on the mechanism of common chemical species present in the liquid products. The contribute hydrogen to stabilize the free radicals produced critical values. Toluene was the main supercritical fluid during liquefaction reaction. The total conversion of Big during liquefaction. Alkylated aromatics and furans are also flowrate of the solvent were not important to the conversion fluid is the fluid at the temperature and pressure above its fluids have gas-like viscosities with very high solubilities. found to consist primarily of saturated hydrocarbons. It illustrated that the free radicals were saturated by hydrogen increase the polarity of the solvent, which increases the more free radicals from coal, inhibit the recombination of not as good as tetralin in producing hydrogen, but it can of Big Brown lignite and yield of liquid, since supercritical radicals to gas. Tetralin and water are good co-solvents for recommended. solvency of supercritical fluids. The liquid product was solvents and co-solvents were investigated. Supercritical supercritical conditions of this study, temperature and these radicals, and prevent the decomposition of these Three solvents were used in the liquefaction studies, To get more liquid products, the main point is to produce toluene, cyclohexane and methanol. Two co-solvents, tetralin used in this study. Tetralin and water as co-solvents can water as a co-solvent in coal hydroliquefaction was |
