“…However, the main technological challenges to be faced [18] in exploitation of such fuels arise from the presence of metals and sulfur. Some papers addressed the particular effects that metals present in solid refinery residues can have on combustion behavior [12,[19][20][21][22][23]. Banik and Pisupati [19] and Li et al [20] showed that V and Ni present in pet-coke cause erosion problems, fouling and clogging, especially under fluidized bed conditions and under CO 2 atmosphere.…”

Heavy fractions of petroleum have for long time been bypassed in favour of lighter fractions. Nowadays, in the framework of the “circular economy”, there is a growing interest in residual petroleum heavy fractions. The present work briefly reviews the use and characterization at laboratory scale of some low valuable solid or semi-solid products of the oil refinery industry: asphaltenes (bitumen/asphalt), pet-coke and pitch for use as fuels. The use of solid and semi-solid refinery residues, in particular, of coke as a coal substitute in thermochemical processes and of pitch and asphaltenes as material precursors, requires careful analysis, and an understanding of their structure at the molecular level is mandatory for the development of processing technology. Techniques for the characterization of typical petroleum heavy fractions such as pitches, asphaltenes and cokes are reviewed. An experimental protocol for investigating at the laboratory scale the thermochemical conversion behavior of solid and semi-solid refinery wastes is proposed.
