| Popis: | Catalytic conversion of Camelina Sativa oil to biodiesel through both conventional heating and microwave radiation was investigated. Three different types of catalysts: homogeneous catalysts (NaOH and KOH), heterogeneous metal oxide catalysts (BaO and SrO), and sol−gel derived catalysts (BaCl2/AA and SrCl2/AA) were evaluated for their efficacy in biodiesel production. The following conditions were obtained for the catalysts based on the maximum biodiesel yield: potassium hydroxide/methanol to oil ratio of 1:9, catalyst concentration of 1% (w/w), and reaction time of 60 s; sodium hydroxide/methanol to oil ratio of 1:9, catalyst concentration of 0.5 wt %, and reaction time of 60 s; barium oxide/methanol to oil ratio of 1:9, catalyst concentration of 1.5% (w/w), and reaction time of 4 min; strontium oxide/methanol to oil ratio of 1:9, catalyst concentration of 2 wt %, and reaction time of 4 min. In the case of sol−gel derived catalysts, different catalyst loading rates in the range of 1−10 mmol/g were evalua... |
