Abstract
This paper present results of the thermal hydrothermal and catalytic cracking of heavy residues. In this investigation. ethyl acetate was used as deasphalting agent because it allows the elimination of both resins and asphaltenes from the oil in only one step. This improves the deasphalted oil Quality as coke pressures and basic nitrogen compounds present in the fraction are practically eliminated. Kinetic measurements of thermal cracking indicate a faster cracking for deasphalted oils. The yield of product oil boiling under 200°C is higher for the deasphalted oil compared with the original feeds. Coke formation shows an opposite trend. Asphaltenes formation decreases with time and temperature due to this latter trend. © 1993, Taylor & Francis Group, LLC. All rights reserved.
