The Delayed Coking Unit is a thermal conversion process, known in the petroleum industry as a process of 'bottom of the barrel'. This unit has a key role in the conversion of vacuum residue in products of higher added value, providing an increase in profitability of the refining scheme. The increasing market competition, the restrictions on product specifications and operational bottlenecks require better control of production planning. Therefore, it is necessary to develop new strategies and mathematical models focused on operational optimization of industrial processes and formulations of products. The difficulty in obtaining modeling and simulation in good agreement with the industrial unit is data quality and degree of detail of the models used, which are highly empirical. This work is based on two parts: the experimental one and mathematical modeling. The main purpose has been to discuss the feedstock characterization, highlighting the use of mass spectrometry for the asphaltenes.
