The delayed coking is a refinery process having the aim of producing vaporised fractions, at the expense of ''coke'' formation, by thermal upgrading of atmospheric or vacuum residues of crudes. Recently an extensive mechanistic model of the delayed coking process has been developed. The obtained light and heavy naphthas are potentially interesting feedstock for olefin production into cracking plants. This paper presents a study of this possible use, based on the simulation of cracking of such type of feedstock with SPYRO(R) program. Some preliminary comparisons of both the models predictions with experimental data are shown.

Abstract
The delayed coking is a refinery process having the aim of producing vaporised fractions, at the expense of ''coke'' formation, by thermal upgrading of atmospheric or vacuum residues of crudes. Recently an extensive mechanistic model of the delayed coking process has been developed. The obtained light and heavy naphthas are potentially interesting feedstock for olefin production into cracking plants. This paper presents a study of this possible use, based on the simulation of cracking of such type of feedstock with SPYRO(R) program. Some preliminary comparisons of both the models predictions with experimental data are shown.File in questo prodotto:
