成果简介	NOVELTY - Additive composition comprises 60-90 wt.% aliphatic alcohol with (4-20C), 0.5-5 wt.% w/w of fatty acid based lubricity improver with (14-20C), 0.5-5 wt.% w/w of polyetheramine based polydispersant with (12-24C), where the diesel fuel is an ultra-low sulphur diesel fuel and where the lubricity improver is selected from ester based lubricity improver compatible with diesel. USE - Additive composition for solubilizing lower alcohols in diesel fuel. ADVANTAGE - The additive composition enhances the dispersability of alkanol in hydrocarbon matrix up to 50% v/v with improved blend stability at low temperature, water tolerance and corrosion protection. Besides the stability of alcohol-diesel blends, the additive composition doped diesel fuel shows improvement in critical properties including cetane no., lubricity and storage stability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: 1. a method for producing the additive composition, which involves blending of alcohols (4-20C) preferably 8-12C in specific ratios at ambient temperature in a range of 25-35℃ with stirring, adding fatty acid based lubricity improver to the blend of alcohols, adding polymeric dispersant preferably polyetheramine (polyEA) having ~1000 MW with 12-24C to the mixture of alcohols and fatty acid with continuous stirring; and 2. a fuel blend comprising diesel fuel, aliphatic alcohols (4-16C), and additive composition, where fuel blend comprises 60 to 90% v/v of the diesel fuel, 5 to 40% v/v of the alcohol (1-4C) and up to 40% v/v of the additive composition.
