Renewable diesel or conventional biodiesel – what is the difference?
Many drivers and boat owners are still often unaware that the law requires a biocomponent to be added to diesel fuel today and sometimes have doubts about the use of biodiesel and how well it can tolerate being stored over an extended period.
Conventional biodiesel (FAME, RME, esters) can encourage water to collect in fuel and also acts as a more attractive medium for microbial growth than hydrocarbon-based fuel. If these types of problems develop, fuel tanks need to be cleaned and, in some cases, use of an antibacterial compound can also be called for. Long-term use of additives or a failure to clean tanks can prolong problems.
The diesel fuel and heating oil sold by Neste Oil does not contain any conventional biodiesel, however, only premium-quality NExBTL renewable diesel, a hydrotreated vegetable oil or animal fat (HVO).
Hydrotreating is a catalytic process widely used in oil refining and takes place at high pressure and high temperatures. The hydrocarbon molecules produced from the crude oil or renewable oil and fat treated using this process are so similar that they cannot be distinguished from each other using conventional means.
Neste Oil produces premium-quality NExBTL renewable diesel from a range of different types of vegetable oil, waste, and residues. Neste Pro Diesel contains NExBTL and is the world's only diesel fuel to comply with the WWFC category 5 specification, the strictest to be drawn up as part of the Worldwide Fuel Charter by automotive manufacturers.
Using Neste Pro Diesel can reduce fuel consumption by as much as 5%, depending on people's driving style and local conditions. It also improves engine performance and reduces vehicle emissions, such as nitrogen oxides, particulates, and hydrocarbons.
