Abstract: The Aspen Plus software was used to simulate the oil shale comprehensive utilization system built with solid heat carrier technology. Moreover, the income and expense distribution of energy and exergy were calculated and analyzed in detail with the simulation results using the energy and exergy analysis approach, and we mapped the flow charts of energy and exergy in the system to describe the energy distribution and energy loss distribution of each thermal process. The results show that when the oil shale input is 100 kg/s, the irreversible exergy loss in internal retort furnace (ie, the exergy loss in the pyrolysis reaction) is 4743%, which accounts toward the most of the lost exergies in the whole system. It was also observed that 1103% of oil shale fuel chemistry energy is devalued as the pyrolysis product heat energy. In addition, among all the heat losses of the comprehensive utilization system, the heat loss energy grade of the condensing unit contributes the most.
