Abstract

The potential of four aromatic additives namely benzene, toluene, xylene, phenol and admixture of the four known as BTXP mixture on the physico-chemical enhancement properties of premium motor spirit (PMS), dual purpose kero (DPK) and automotive gas oil (AGO) has been investigated in this work at varying ratios. Additives to distillate volume ratios of 10:90, 20:80,30:70 and 40:60 were used. The results show that as the volumes of additives in the 100ml mixture increase the densities, flash points, boiling points and viscosities of the distillates increase. Also as the volumes of additives in the 100ml mixture increase, the degree API, thermal conductivities, specific heat capacities and heat capacities decrease. It is note worthy that the degree of influence is dependent on the different levels of additives added. The best additive to volume ratio of 10:90 was obtained for all the fractions. Xylene was adjudged as the best additive that can be used to obtain the best quality distillates.
