在CIM-6油脂氢化催化剂及其相关技术的基础上,研制成功CIM-7脂肪酸氢化催化剂和CIM-8脂肪酸甲酯氢化催化剂.又在相同条件下对十八碳烯酸加氢,同Pricat 9932-6(Unichema International),KE-FS40(Sud-Chemic Ag.),G-53-1(U.C.I.)催化剂对比,考察了CIM-7的催化性能;当温度、压力、搅拌、时间相同,改变催化剂质量分数对不同酸值的棕榈油甲酯加氢,同SD-250(吉野Co.)催化剂对比,考察了CIM-8的催化性能.结果表明:(1)产品硬脂酸的碘值(g I2/100 g)分别为0.76(CIM-7)、0.85(Pricat 9932-6),1.04(KE-FS40),1.28(G-53-1),即催化活性和抗酸性CIM-7＞Pricat 9932-6＞KE-FS40＞G-53-1.(2)当原料酸值为1.1 mg KOH/g、w(催化剂)=0.20%时,产品氢化棕榈油甲酯碘值(g I2/100 g)为1.12(CIM-8),24.07(SN-250);当原料酸值为0.03 mg KOH/g,w(催化剂)=0.076%时,产品碘值为1.90(CIM-8),12.18(SN-250),即催化活性和抗酸性CIM-8＞＞SN-250.3.产物中w(镍)=38.5×10-6(CIM-7),41.2×10-6(Pricat 9932-6),48.7×10-6(KE-SF40),57.4×10-6(G-53-1);1.18×10-6(CIM-8),1.83×10-6(SN-250),即催化剂的镍流失量CIM-7＜Pricat 9932-6＜KE-FS40＜G-53-1;CIM-8＜SN-250.
