Differential thermal analysis of n-long chain alcohols and corresponding alkoxy ethanols

The differential thermal analyses of n-long chain alcohols CH3(CH3)n-1-OH, designated as Cn-OH (n = 16, 18, 20 and 22), and corresponding alkoxy ethanols CH3(CH2)n-1-OCH2CH2OH, designated as Cn-OC2H4OH, have been carried out at a heating rate of 1°C min-1. The differential e.m.f (Δ∨ ) has been plotted against the temperature of the reference material (°C) and the onset of the peak has been taken as the appearance of the polymorphic phase transition or melting of the compound. Heats of transition (ΔH1) and melting or fusion (ΔH1) were computed from the areas under the respective peaks

Visbreaking studies on Aghajari long residue

Visbreaking studies on Aghajari long residue (370 °C+) have been conducted in a continuous bench-scale unit at different severity conditions. The effects of temperature and residence time on the yields and properties of the visbroken distillates and residues have been studied. The kinetics of cracking has been determined to be first order
