    Antioxidants, colour stabilisers, acidity neutralisers

    This section of our catalogue presents special reagents, which are used to preserve marketable and serviceable properties of fuel.


    Few kinds of oil products are stable in contact with atmospheric oxygen. Very unstable boiler and furnace fuels, gasolines with high-octane additives, which, due to the presence of alkenes in their composition are very prone to oxidation. As a result of the reaction with oxygen, especially in the light, the fuel darkens, loses its marketable appearance and its technical qualities are reduced.

    In order to improve the chemical stability of fuel, an antioxidant oil additive — a special additive that works most effectively in petrol and jet fuel — is added.

    At the moment there are many types of antioxidants which work differently: the «simplest» antioxidants simply cut off the chain reaction of free radical formation and «die» themselves, while more modern ones regenerate and react again. Some of them reinforce each other’s action if administered simultaneously. Of course, they are different in nature. Phenols, nitro compounds, quinones, sulphur, nitrogen and phosphorus compounds, as well as their mixtures that exhibit synergistic effects. They are selected according to the conditions of use, and depending on the convenience of one or another product.

    Buying antioxidant fuel is the first thing you should do in order to maintain its marketability and performance. Another name for antioxidants is colour stabilisers. This term is derived from their most visible effect, which is the preservation of the original appearance and transparency of fuel, which many perceive as the most indicative of petroleum product quality.

    Acid neutralizers

    The causes of fuel oxidation have been outlined above. Obviously, the longer it is stored, the more variable its merchantability and performance is. The same reasons, as well as multiple pumping, temperature changes, microbial growth in tanks, lead to increased acidity of fuel, increased corrosion efficiency and formation of tars.

    Special technical measures — lowering temperature, limiting air and light access, acid washing — only help to slow down the oxidation processes, but do not avoid them. Therefore the most effective method of counteracting oxidation is to add neutralizers to lower the acid number and maintain the required pH level.

    An acid neutraliser is added based on the original acid number, and when properly sized, not only helps to restore fuel to its original quality, but also protects engines and tanks from corrosion, and prolongs the storage life of fuel.

    Antioxidants, acid neutralisers and colour stabilisers can be purchased in this section of our catalogue.
