    Abstract

    Cloud point measurements are presented for additives in two test diesel blends and jet fuel. Additive functionalities studied include diesters, esters, ketones, ethers, and alkanes. Diesters, as a class, create liquid-liquid immiscibility and a cloud point higher than that of either the base fuel or the pure diester. Esters decrease the cloud point of diesels fuels, as do most ketones. Ethers and alkanes, respectively, decrease the cloud point even more. These results are consistent with the precipitation of a component of the petroleum fuel, rather than an additive, and the decrease in cloud point is due to a dilution effect. For some ketones, a different effect is observed. Based on the pure component melting temperature of the ketone, the compounds studied cause decreases or increases. Long chain ester components were also tested. These additives have higher cetane numbers than other potential fuel components, and are more desirable as a diesel fuel component. Ketones and ethers of similar lengths were also tested, and have the same behaviors as described above. The behavior of potential fuel additives seems to be more related to the oxygen containing functional group rather than extent of branching or size. Experimental results are interpreted with thermodynamic models using modified surrogates. This is an abstract of a paper presented at the 2012 AIChE Spring Meeting and 8th Global Congress on Process Safety (Houston, TX 4/1-5/2012).
