Enhancement in Viscosity of Diesel by Using Chemical Additive

The effects of four different additives for viscosity enhancement of diesel were studied. Two different additive used are namely Ethylene-propylene copolymer, T-818C Copolymer of maleic acid ester, acrylic ester and vinyl acetate, both of these additives were added in different proportion and studies its relative effect on viscosity of base diesel. It is difficult to adjust the small quantity addition of viscosity modifier because of its high viscosity. Hence it was diluted with higher concentration. And then different dilution was made by diluting this mother concentrate. Raise in viscosity of base diesel observed were from 2.6 to 12.8% in case of EPC and 1.95 to 9.76% in case of T-818C Copolymer of maleic acid ester, acrylic ester and vinyl acetate . After each addition of viscosity modifier it s effect on remaining key parameter of diesel were studied.
