摘要
考察了草酸盐胶体共沉淀法超细Ｃｕ／ＺｎＯ／Ａｌ２Ｏ３合成甲醇催化剂的催化性能，并在相同条件下与国外的ＩＣＩ－５１－３合成甲醇催化剂作了比较。结果表明，在２．０ＭＰａ、２３０℃、空速６０００ｈ－１条件下，超细催化剂的甲醇时空产率为０．４９ｇ／（ｇｈ），高于ＩＣＩ－５１－３催化剂；同时对催化剂进行了表征。
Activity of an ultrafine Cu/ZnO/Al 2O 3 catalyst prepared by gel oxalate coprecipitation (GOCP) is evaluated at different temperatures and space velocities for methanol synthesis.The results show that the space time yield of methanol reaches 0 49g/g cat·h by using the ultrafine catalyst at 2 0 MPa,6000 h -1 and 230℃,higher than that by using overseas ICI 51 3 and BASF catalysts in the same reactor under the same reaction conditions.The XRD and TEM results show that they are different in structure.
