  • Can rapeseed be used as a feedstock for biodiesel?
  • For more information on the journal statistics, click here . Multiple requests from the same IP address are counted as one view. Rapeseeds are desirable as feedstock for manufacturing biodiesel due to their high production capacity and oil yield.
  • How is rapeseed biodiesel produced?
  • Rapeseed biodiesel production is energy intensive and inefficient on a commercial scale. Raw seeds must be collected in the agricultural phase and then dried and stored prior to extraction, which may be accomplished physically through pressing or chemically through conditioning, solvent extraction, and distillation.
  • Does ball milling rapeseed produce methyl esters?
  • Ball milling rapeseeds prior to refluxing with the rapeseed oil produced methyl esters, suggesting that the rapeseed shells contain a mechanophore that is only activated by the collisions within the ball mill, and milling time affects the activation and, therefore, the final product of transesterification.
  • How much energy does rapeseed consume?
  • Energy Consumption Based on the 2013 study completed by Rajaeifar et al., a typical process for the production of biodiesel from 1 hectare of rapeseed consumes approximately 28,100 MJ, separated into four steps of agricultural crop production: transportation, oil pressing, transesterification, and, finally, biodiesel.
  • What is the kinematic viscosity of rapeseed oil?
  • 3.4. Viscosity The rapeseed oil was found to have a kinematic viscosity of 42 cST, and biodiesel produced from the high-energy ball mill had a kinematic viscosity of 18 cST. ASTM standards require kinematic viscosity to be in the range of 1.9 to 6.0 cST.
  • Does rapeseed have a metal center?
  • However, an initial hypothesis is that the molecule has a metal center, as all previously discovered mechanocatalysts have consisted of metal centers, including but not limited to cobalt, copper, iridium, iron, and nickel, and rapeseed has been found to contain trace amounts of metals such as nickel, iron, and copper [ 32, 33 ].
