This paper presents the general layout and main features of a new method for utilising oil shale: integrated tri-generation system. This new scheme is expected to be more efficient and environment-friendly, as well as a less-costly method, for producing electric power and synthetic (i.e. liquid and gaseous) fuels from oil shale, compared with traditional utilisation methods. By integrating the gasifier, circulating fluidised-bed combustor (CFBC), retort and combined-cycle turbine system in one plant, higher efficiencies can be achieved as well as lower costs of the final products.
