The characteristics and kinetics of co-pyrolysis of furfural residue with oil shale semi-coke

Abstract

In the present work, the thermogravimetric analysis-Fourier transform infared spectroscopy (TGA-FTIR) system was employed to investigate the co-pyrolysis behavior of oil shale (OS) semi-coke (SC) and furfural residue (FR). Results indicated that the addition of furfural residue improved the pyrolysis characteristics of blends, while synergy behaved differently with the variation of the mixing proportion. Semi-coke could act as a catalyst for the furfural residue pyrolysis and facilitated the release of hydroxyl, but slightly inhibited the release of CO 2 and CH 4 . The optimal blending ratio of oil shale semi-coke to furfural residue was 1:1. Besides, kinetic parameters were calculated using model-free methods, declaring that the sample pyrolysis was a multi-process.

[Retracted] Experiment and Algorithm Research of Coal Direct Liquefaction Residual Oil Pyrolysis and Coking Technology Based on Lumped Kinetic Engineering

“…For example, Colantonio [7] conducted a pyrolysis experiment on a synthetic mixture of packaging plastic residues; Wang [8] conducted pyrolysis experiments on wood and forest residues and studied the carbon dioxide gas kinetics of pyrolysis coke; Wang [9] launched a continuous pyrolysis experiment of biomass coal residues and analyzed the results. Chen [10] studied the copyrolysis characteristics and kinetics of furfural residue and oil shale semicoke. It can be seen that since the development of this technology, its innovation and application research have received the attention of the majority of researchers.…”
