CaO／MgO／γ-Al2O3固体碱催化棕榈油制备生物柴油工艺条件优化
Process optimization for preparing biodiesel f rom plam oil with CaO/MgO/γ-Al2 O3 solid base catalyst
摘要
Abstract
Supported CaO/MgO/γ-Al2 O3 solid base catalysts were prepared by using impreg-nation method .The optimal preparation conditions of catalyst which has good catalytic effect were defined as follows :the molar ratio of Ca to Mg is 4∶1 ,calcinated at 750 ℃ for 12 h ,and mass ratio of CaO to γ-Al2 O3 is 18% .It was used to catalyze methyl esterification of palm oil . The results showed that the highest yield was 95 .3% when the molar ratio of methanol to oil was 7∶1 with addition 3 .5% (wt% )CaO/MgO/γ-Al2O3 of oil and reacted at 60 ℃ for 2 h .关键词
