Abstract

Pyrolysis experiments have been conducted on Goynuk oil shale in a Heinze retort at atmospheric pressure using static, nitrogen and steam atmospheres and in a fixed-bed reactor using hydrogen pressures up to 150 bar (hydropyrolysis). As well as high pressure hydrogen, the use of steam as a sweep gas increased oil yields considerably. Moreover, for both regimes, the composition of the tars confirmed that hydrocracking reactions had occurred to a significantly greater extent than in the static and nitrogen atmospheres.
