Abstract

Factors influencing the pyrolysis of Yaojie oil shale, such as pyro­lysis temperature, residence time, heating rate and particle size, were investigated. Pyrolysate yield was influenced most of all by pyrolysis tem­perature and residence time, followed by heating rate and particle size. Pyro­lysis temperature and residence time had a great effect on the composi­tion of retorting gas, while the influence of heating rate and particle size was less significant, corresponding to a change of oil yield of only 0.6% and 0.5%, respectively. The oil and gas yields were less affected when the oil shale sample was pressed into balls. The oil shale ball with a bentonite content of 6% was optimal.
