Ultra Low Sulphur Diesel (ULSD)
Used for all diesel engined vehicles intended for use on the public highway.
Diesel in general is any fuel used in diesel engines. The most common is a specific fractional distillate of petroleum fuel oil, but alternatives that are not derived from petroleum, such as biodiesel, biomass to liquid (BTL) or gas to liquid (GTL) diesel, are increasingly being developed and adopted. To distinguish these types, petroleum-derived diesel is increasingly called petrodiesel. Ultra-low sulfur diesel (ULSD) is a standard for defining diesel fuel with substantially lowered sulfur contents. As of 2007, almost every diesel fuel available in America and Europe is the ULSD type. In the UK, diesel is commonly abbreviated DERV, standing for Diesel Engined Road Vehicle (fuel).
Bio blend diesel consists of a uniform mixture of two diesel fuels:
- A mineral distillate (95% by volume) of ULSD
- A vegetable distillate (5% by volume) of Bio-diesel
Bio-diesel is considered as environmentally favourable’. Plants in their growth utilise the carbon dioxide in the atmosphere to synthesise biomass. The oil is extracted from biomass and later ‘burnt in diesel engines’ A by-product of this combustion is carbon dioxide. The process of incorporation and subsequent release is ‘regarded’ as a closed cycle i.e. what is taken from the atmosphere is returned from the atmosphere. There is no increase in the carbon dioxide burden on the environment.
The blend (95/5) meets the latest requirements of the relevant British and European specification BS EN 590.
The blend confers desirable performance related properties to the fuel such as; smoke control and reduced particulates.
