Abstract | ||||
The pyrolysis of Ellajjun (Jordan) oil shale was carried out in a fixed bed retort in temperature range of 360 – 550oC using either nitrogen or nitrogen-steam mixture as sweeping gas. Differences were observed between the total weight loss and product compositions. Pyrolysis under nitrogen-steam mixture gave larger increase in weight loss as pyrolysis temperature increased. The retorted shale oil samples under the influence of either nitrogen or nitrogen-steam were distilled. The gasoline- naphtha and kerosene fractions from simple atmospheric distillation, were increased by 35% and 65% (vol.) respectively while, diesel fraction was decreased by 45% vol. compared with nitrogen pyrolysis. | ||||
