摘要：A structure-oriented lumping (SOL) model to predict the product distribution of delayed coking was built. The effects of feedstock properties and operational conditions on product distribution were analyzed with the proposed model. It was known from model calculation results that for the feedstock residue of this paper, the liquid yield increased 2.5% on average with a temperature increase of 10 C, that mainly was equal to a 0.15 increase H/C of feedstock; the liquid yield increased 3.5% on average with a recycle ratio decrease of 0.15, that was mainly equal to a 5% carbon residue decrease of feedstock; and liquid yield increased 0.6% on average with a pressure decrease of 0.03 MPa.
