LANXESS Introduces New Baynox Stabilizers for Biodiesel

Pennsylvania, USA — Specialty chemicals company LANXESS Corporation has added two new highly concentrated antioxidants to its existing range of biodiesel stabilizers. The new products – Baynox Ultra and Baynox Cargo – were introduced to the U.S. market at the National Biodiesel Conference & Expo January 19 – 22 in Fort Worth, Texas.

Baynox Ultra, a highly active liquid oxidation stabilizer, is an easy-to-use additive that effectively prolongs the shelf life of biodiesel, especially for soybean and sunflower methyl esters. It contains a balanced blend of highly active antioxidants and a chelating agent dissolved in a “green” solvent. With an active content of more than 40 percent, Baynox Ultra is typically added in a concentration of 200 to 500 ppm to the biodiesel. Since the stabilizer does not crystallize, it can be used reliably at temperatures as low as 20 degrees Fahrenheit (°F).
Baynox Cargo is a ready-to-use solution of the established Baynox antioxidant in an organic solvent, which has been developed as an oxidation stabilizer for the treatment of biodiesel cargos. It has an active content of more than 35 percent. The solution has a low viscosity and a flash point above 140°F for easy handling. It remains liquid even at 20 degrees Fahrenheit (°F).

Tony Mazzarella, NAFTA Business Manager, explains: “The highly concentrated antioxidants Baynox Ultra and Baynox Cargo ensure that the biofuel obtained from natural raw material remains stable and can be used for longer. Otherwise, the fuel's unsaturated fatty acid structures can easily oxidize in contact with atmospheric oxygen. Heat, light and pressure make the oil rancid within a short time.”
The consequences of such oxidation are a degradation of the biodiesel into short-chained fatty acids and the formation of insoluble polymers (gums), which can cause damage to the engine and the injection system. LANXESS' Baynox range is continually being adapted to the rapid developments in the automotive industry and includes increasingly high-performance products. The pressures in diesel engines are continually rising, as are the injector temperatures. On the other hand, tolerances for manufacturers of biodiesel are getting smaller and smaller and the specifications ever narrower. “With Baynox Ultra, our customers will be ideally equipped to meet the demands of modern fuels made by the automotive industry,” says Mazzarella.

Studies by Wood-Mackenzie (June 2014) and Hart Energy (November 2014) predict significant growth for biodiesel in the U.S. and Asia in the next 10 years, as well as steady demand in Europe – currently the largest biodiesel market. This is being driven by various legal regulations in the different regions, such as the introduction of greenhouse gas limits and an increase in the proportion of biogenic substances in diesel fuels.
