| 英文摘要 | In the present study, thermal decomposition behaviors and kinetics for fast pyrolysis of acid/alkali pretreated waste cassava residues were investigated. The results demonstrated that chemical pretreatments apparently loosened the compact structure of cassava residue and benefited to the sufficient contact with acid/alkali sites. Acid/alkali pretreatments enriched the product varieties and had remarkable influence on the adjustment of product formation. Particularly, the pyrolysis behavior obviously shifted to low-temperature zones for pretreated samples. Low heating rate significantly promoted the formation of anhydrosugars with 27% levoglucosan produced, while elevating heating rate contributed to furfural production. Some oxygenated-chemicals, such as acetic acid, hydroxyacetone and 4-hydroxydihydrofuran-2(3H)-one, were apparently formed in the presence of alkali metal. Noticeably, the generation of most gaseous products was restrained for those acid-impregnated cassava residues. Moreover, kinetic study suggested that the apparent activation energy for waste cassava residue pyrolysis was significantly lowered, further verifying the positive role of chemical pretreatments.
