โœฆ Synopsis

Nonisothermal rate measurements for the evolution of Hz, CH4, C2 hydrocarbons and C3 hydrocarbons during the pyrolysis of Colorado oil shale have been analysed using the recent kinetic theory of Antony and Howard AIChE J. 1976, 22, 625. This analysis yields a simple set of rate expressions, which can be used for modelling kerogen pyrolysis under typical retort heating conditions. A stoichiometric representation of kerogen pyrolysis is also developed, These results are then used to derive a simple mechanistic picture of oil shale pyrolysis between 25 and 900ยฐC.

The rate of evolution of CH4, CO, CO2, Hz, C2 hydrocarbons, and C3 hydrocarbons during pyrolysis of Colorado oil shale between 25 and 900ยฐC is reported. All experiments were performed nonisothermally using linear heating rates varying from 0.5 to 4.0ยฐC min-'. Hydrogen is the major noncondensable ga
