摘要：

The thermal behavior of Longkou oil shale semi-coke, furfural residue and their blends was researched in this paper. The experiment was carried out using TG-FTIR to research the combustion mechanism, under different heating rate (10, 20, 40 and 80 degrees C/min) and simulation of air condition (80% nitrogen: 20% oxygen). The oil shale semi-coke was blended with furfural residue in proportions from 20% to 100%. Two following factors were studied: heating rate and mixing ratio. The combustion behavior of semi-coke can be promoted furfural residue. And the synergistic effect was calculated by means of interaction coefficient f and the Relative Error of Mean Square root. The combustion of two samples can be divided into two stages, and three stages of co-combustion. Synergy occurred in every stage. At the same time, the co-combustion kinetics parameters were calculated by the Coats-Redfern method. The activation energy of the mixtures first decreased and then increased with the degree of reaction. (C) 2017 Elsevier Ltd. All rights reserved.
