Phase transitions in middle-distillate waxes: effect of a pour-point depressant additive

The phase transition temperatures and energies of petroleum waxes derived from Bombay High middle distillate were determined. The effects of iso- and cycloparaffins and aromatics, individually and collectively, on these parameters were investigated. The influence of a commercial pour-point depressan...

Summary:The phase transition temperatures and energies of petroleum waxes derived from Bombay High middle distillate were determined. The effects of iso- and cycloparaffins and aromatics, individually and collectively, on these parameters were investigated. The influence of a commercial pour-point depressant additive and its concentration on the same parameters were also studied. The mechanism of pour-point depression is discussed in terms of changes in these parameters.
