Catalytic production of biodiesel from corn oil by metal-mixed oxides
The present study investigates the transesterification of corn oil with methanol over two oxides of MgO and ZnO at 65 ͦC and 1 atm. These two catalysts have been prepared via a conventional co-precipitation process. As for MgO, the corresponding mixed metal nitrate solution has been mixed and heated at the presence of urea. ZnO has also been synthesized by co-precipitation of metal acetate at th...

متن کاملInfluence of corn oil recovery on life-cycle greenhouse gas emissions of corn ethanol and corn oil biodiesel
BACKGROUND Corn oil recovery and conversion to biodiesel has been widely adopted at corn ethanol plants recently. The US EPA has projected 2.6 billion liters of biodiesel will be produced from corn oil in 2022. Corn oil biodiesel may qualify for federal renewable identification number (RIN) credits under the Renewable Fuel Standard, as well as for low greenhouse gas (GHG) emission intensity cre...
متن کاملProduction and evaluation of biodiesel and bioethanol from high oil corn using three processing routes.
Six Korea high oil (KHO) corn varieties varying in germ and endosperm size and oil content (4-21%, wet basis) were subjected to three sequential combinations of milling (M), germ separation (S), fermentation (F), and in situ transesterification (T) to produce bioethanol and biodiesel. Production parameters including saccharification, bioethanol yield, biodiesel yield and composition, and conver...
متن کاملOptimization of formic acid hydrolysis of corn cob in xylose production
−Dilute acid pretreatment of lignocellulosic material is one of the significant steps in a biorefinery. We used response surface methodology to determine the important factors of formic acid concentration (2%-6% wt%), treatment time (30-150 min), reaction temperature (120-160 oC), and liquid to solid ratio (3-11 mL/g) on dilute acid hydrolysis of corn cob to produce xylose. A xylose yield of 81...
