Abstract
To study the performance and reaction kinetics of direct coal liquefaction for Shenhua Shangwan coal bituminous coal, experiments were carried out in a 0.01 t·d?1 continuous tubular facility using the hydrogenated anthracene and wash oil as solvent and FeOOH as catalyst in the range of residence time 7—110 min, reaction temperature 435—465℃. The results showed that, as the coal pyrolysis and a series of hydrogenation proceed, coal and PAA yields continue to decrease, heavy liquefied product gradually transformed to light liquefied product. When the reaction temperature is 455℃, residence time of 90 min, the coal conversion reached 90.41% (mass) and oil yield 61.28% (mass) respectively, and with the reaction conditions were further harsh, the oil yield will decrease. Based on the reaction characteristics of Shenhua Shangwan coal and its data from experiments, 11 lumps reaction kinetics model was build and BFGS optimization algorithm was adopted to get reaction kinetics parameters. The kinetics model better predicted the reaction behavior of direct coal liquefaction of Shangwan coal in isothermal stage.关键词
