This book summarizes the results of the investigations on the characterization of heavy oils performed in the Research laboratory of “LUKOIL Neftohim Burgas”, and in the University “Prof. Dr. Assen Zlatarov” Burgas for the period 2011-2016. It also deals with the results obtained in the laboratory and commercial studies of the heavy oil upgrading processes fluid catalytic cracking, visbreaking and ebullated bed hydrocracking carried out in the University “Prof. Dr. Assen Zlatarov” Burgas and at the commercial units in “LUKOIL Neftohim Burgas” refinery for the same space of time. The book is intended to shed more light about heavy oil characterization by the use of easy accessible methods, which can be available in refinery, and to relate this information to the heavy oil upgrading process performance. The book is also devoted to discussing the performance of the processes fluid catalytic cracking, thermal cracking (visbreaking), and ebullated bed residue hydrocracking in laboratory and commercial conditions.
