Pyrolysis Kinetics of Oil Shale From Northern Songliao Basin in China

Abstract

Pyrolysis experiments on northern Songliao basin oil shale were carried out by Rock-Eval analyzer at five different heating rates of 10, 15, 20, 25 and 30 °C/min. Pyrolysis characteristics of oil shale were investigated at different heating rates. Kinetic parameters of oil shale pyrolysis were determined by using Friedman procedure and global first-order kinetics. From Friedman procedure, it is concluded that most reactions occur with the activation energy of 165-545 kJ/mol. The linear relationship between activation energy and logarithm of frequency factor was obtained. The values of activation energy and frequency factor, deduced from the first-order equation case, are used to predict pyrolysis time. It is found that pyrolysis time is correlating with pyrolysis temperature.

Pyrolysis of Oil Shale Mixed With Low-Density Polyethylene

“…Oil shale is the second largest solid fossil fuel resource after coal in the world [1]. China is one of the many countries with large oil shale deposits, which are estimated at 6×10 11 tonnes [2] and are mainly located in Fushun, Northeast China [3]. So far, the only known major source of fossil energy fuel in China is oil shale, whose utilization as a substitute for petroleum is of crucial importance for state's development.…”
