Abstract. The paper studies the influence of additives on diesel fuel properties. Methods of improving low-temperature properties of diesel fuel by means of catalytic dewaxing on an industrial scale are considered. The chemistry of catalytic dewaxing process is considered. Process catalysts, their composition, functions and reactions occurring at their use are considered. Material balance of catalytic dewaxing unit is given. Methods of low-temperature properties improvement by introduction of depressor-dispersing additives are considered. Requirements to additives are outlined. The influence of depressor-dispersing additives on physical and chemical properties of diesel fuel is investigated.
