FuelMatic™ System Specifications
Input parameters and requirements
The following requirements are necessary for an effective operation of the FuelMatic™ biodiesel production system.
 |
| Input fresh oil |
Customer defined tonnage |
| Amount of Sodium or Potassium Methylate (30% solution in Methanol) |
2% of input oil |
| Amount of Methanol |
13.5% of input oil |
| Amount of Amberlite™ BD10DRY™ |
0.1% of input oil |
|
| *The addition of an oxidation stabiliser to ensure a longer storage ability of the biodiesel as well as the addition of an additive for the winter stability during the winter months have not been considered for this overview. Green Fuels recommends and supplies Cold Flo 350 as a winter additive. |
|
For the quality of the fresh oil, pure rape seed oil used as vehicle fuel is used as basis.
Product parameters
The quality of the produced biodiesel will be in correspondence with the European standard DIN EN 14214 and USA ASTM 6751, if the requirements are met.

Some of the parameters defined in the standard EN 14214 (e.g. CFPP, phosphorus content, oxidation stability) and ASTM 6751 are determined by the type and quality of the input materials used. They can not be influenced by the transesterification process itself. It has to be mentioned that it is not possible to reach the required CFPP value for biodiesel from used vegetable oils and certain types of fresh oil (e.g. palm oil) without prior pre-processing of these oils. Therefore the winter stability of biodiesel from used vegetable oils cannot be assured and may require a post-process and/or additive.
