摘要: 考察了预处理条件对糠醛渣乙二醇液化的影响.结果表明:经过5% NaOH溶液与2.5% H2O2溶液体积比1:1的混合液预处理后,在固液比为1:10(g:g),催化剂用量3%,150 ℃液化90 min后,液化率达到82.0%.通过扫描电子显微镜(SEM),X射线衍射(XRD),红外光谱(FI-IR)以及核磁共振光谱(13C NMR和1H NMR)对预处理前后糠醛渣及液化产物进行分析,结果表明,本预处理方法显著改变了糠醛渣的组成、表面结构,且增强了催化液化的反应活性,十分有利于促进其液化降解过程,液化产物主要为醇、酯、醚等混合物.

Abstract: The effects of pretreatment technology on the liquefaction of furfural residue in ethylene glycol were investigated.The experimental data showed that the liquefaction rate of furfural residues,which was pretreated via using the intermixture of 5% NaOH and 2.5% H2O2 at the ratio of 1:1(mL:mL), could reach 82.0%,under the conditions of 150 ℃ for 90 min with the solid-liquid ratio of 1:10(g:g) and catalyst dosage of 3%, respectively.Meanwhile, the furfural residues before and after the pretreatment as well as the liquefaction products were analyzed and characterized by scanning electron microscopy(SEM), infrared spectra (FT-IR), X-ray diffraction spectrum (XRD),13C NMR,and 1H NMR,respectively.The results showed that the composition and surface structure of furfural residues were changed in pretreatment process.It was beneficial to improve the liquefaction process of furfural residue.And the liquefaction products included alcohols,esters,ethers and so on.

Key words: furfural residu, ethylene glycol, pretreatment, catalytic liquefaction
