The invention belongs to the field of environmental protection, and particularly relates to a combustion desulphurization product for furfural residue. The invention provides a combustion desulphurization agent for the furfural residue, which comprises one or various components selected from magnesium oxide/magnesium nitrate/magnesium carbonate, barium oxide/barium carbonate/nitrate barium, and alumina/aluminum nitrate. According to the combustion desulphurization agent, raw materials of the desulphurization agent are inorganic minerals with wide sources and available materials; the waste residue after desulphurization reaction is discharged in the form of solid state, so as to be easy to conduct post processing, and reduce the atmospheric environment pollution; meanwhile, compared with the conventional desulphurization agent, the material property is more stable, safe, and environment-friendly, the selection for types of desulphurization agents is more various, the desulphurization effect is more optimized, and the desulphurization rate can reach 65%-85%. Therefore, combustion desulphurization agent has better socioeconomic performance.
