概要:

This thesis proposes a new technology-catalytic decarboxylation of waste cooking oil over MgO-based catalyst that overcomes the high quality biodiesel (HiBD) production. The supported MgO catalysts were successfully prepared by incipient we … tness impregnation method and tested in an agitated reactor at 430℃ under helium. The effect of support material (γ-Al₂O₃, SiO₂, ZrO₂ and AC) on MgO based catalyst was investigated. All catalysts can convert triglycerides into hydrocarbons in diesel range via two parallel pathway: decarboxylation or subsequent cracking reaction. The effect of the addition of CaO and ZrO₂ on MgO supported on SiO₂ and AC was also studied. The addition of CaO and ZrO₂ significantly improved the catalyst activity and stability which gave lower acid values in comparison to the monometallic supported MgO. The addition of CaO lead to the formation of increased lighter hydrocarbons, whereas the addition of ZrO₂ was found to increase the yield in diesel fraction. 続きを見る
