COMPOSITIONAL AND STRUCTURAL STUDIES OF V1SBROKEN RESIDUES

Abstract
Visbroken residues (150°C+) obtained from soaker visbreaking of a short residue under different severity conditions were characterized for structural and compositional details by IR, H-n.m.r, Column Chromatography VPO and other classifical techniques. The variation of these parameters/data with severity of operation measured in the term of conversion (wt % yield of 150°C) were used to explain the reactions occurring and quality of fuel oil produced.
