摘要
采用所研制的ＦＳ－９０型Ｃｕ－Ｃｒ／Ａｌ２Ｏ３催化剂进行糠醛加氢合成２－甲基呋喃。研究了反应温度、压力、空速、氢／醛摩尔比对２－甲基呋喃收率的影响。２－甲基呋喃收率达９６．６％，经６００ｈ寿命试验，２－甲基呋喃收率在９０％以上，与常用的Ｃｕ－Ａｌ合金催化剂相比具有收率高、稳定、寿命长的特点。电镜测试结果表明，催化剂表面呈层状分布，有助于活性组份在层状结构上分布均匀；活性组份颗粒粒径呈窄分布，有助于提高选择性、稳定性和产品收率。
methyl furan(2 MF)was synthesized from furfural by hydrogenation using Cu Cr/Al 2O 3 catalyst FS 90(the ratio of copper to chromium is 7∶3).The effects of reaction temperature,pressure,space velocity,molar ratio of hydrogen/furfural were studied.The yield of 2 MF is 96 6%,and after 600 h,the yield is still above 90%.Compared with the conventional Cu Al alloy catalyst,FS 90 catalyst has such characteristics as higher yield and better stability.SEM study indicates that improvements in selectivity and stability are due to the even distribution of the particles of active components which are of a narrow size distribution.
