Liquid phase furfural hydrogenation to 2-methyltetrah

摘要:

采用溶胶-凝胶法制备了Cu/Ni超细混合催化剂，并用于糠醛液相加氢制2-甲基四氢呋喃反应。考察了Cu/Ni摩尔比，Na2CO3溶液浓度等催化剂制备条件，以及合成反应中反应压力、反应时间、反应温度等反应条件对糠醛转化率和2-甲基四氢呋喃选择性的影响。结果表明：催化剂制备条件为Cu/Ni摩尔比为5/5，Na2CO3溶液浓度为1.0 mol/l；合成反应条件为反应压力8 MPa，反应时间3.5 h，反应温度180 ℃；产品经气相色谱检测分析，糠醛的转化率为100%，2-甲基四氢呋喃的选择性为64.52%。

Abstract:

The Cu/Ni ultrafine mixed catalyst were prepared by sol-gel technique, the catalysts were applied for liquid phase hydrogenation of furfural to 2-methyltetrahydrofuran. The effects of Cu/Ni molar ratio, concentration of Na2CO3 solution on the properties of the catalyst were investigated, and the effects of reaction pressure, reaction time, reaction temperature on the conversion of furfural and selectivity to 2-methyltetrahydrofuran were studied in detail. The results indicated that catalyst preparation conditions under Cu/Ni molar ratio 5/5, concentration of Na2CO3 solution 1.0mol/l, liquid phase hydrogenation under reaction pressure 8MPa, reaction time 3.5h, reaction temperature 180℃, The conversion of furfural and the selectivity of 2-methyltetrahydrofuran were 100% and 64.52% respectively by GC analysis.
