DEVELOPMENT OF MULTIFUNCTIONAL ADDITIVES BASED ON VEGETAL OILS FOR HIGH QUALITY DIESEL AND BIODIESEL FUELS
Multi-scale and/or multi-disciplinary approach to process-product innovation

Keywords: multifunctional additives, vegetable oil, lubricity, detergent-dispersant
The increasing qualitative requirements of the fuels of modern Diesel engines can be satisfied by applying environmental friendly blending components of high energy content and additive-packages having high performance level. The fatty acid methyl esters and/or their derivatives are able to replace a part of the diesel fuels and/or their additives (for example: lubricity improvers). From the aspects of environmental protection the use of esters synthesized on vegetable oil base gives advantages for this high quality Diesel fuel.
The aim of our experimental work was to produce vegetable oil-based multifunctional additives which have not only lubricity improver effect applying in fuel but other necessary properties can be achieved, too. Beside, our object was to use raw materials originated from partly renewable source meeting the biodegradability requirements. During our research work intermediates were produced with the use of polyisobutylene, maleic anhydride and rape-oil methyl ester by radically initiated method. These intermediates were used to acylate polyethylene polyamines. Beside the lubricity improving effect the analytical and efficiency tests of the final products showed identical or even better detergent-dispersant properties compared to the traditional PIB-succinimides. These synthesized additives also provided other functional effects such as corrosion inhibiting and antifriction effects.
