    摘要: A predictive kinetic model is disclosed for simulating fluid catalytic cracking of large hydrocarbon molecules having a lumping scheme that includes hydrocarbon descriptions based on boiling point distribution and chemical properties. The simulation results in a nearly continuous prediction of products as function of boiling point temperature. The lumping scheme defines a relatively large number of small fixed boiling-point range pseudo-components for describing product material, and a smaller number of larger boiling-point range pseudo-components for describing feed conversion and selectivity. The chemical properties for describing hydrocarbons include total hydrogen, aromatic carbon and aromatic hydrogen.

    摘要: A method to rapidly characterize the hydrocarbon chemistry of heavy residual petroleum mixtures uses three model equations for predicting aromatic carbon content, aromatic hydrogen content and total hydrogen content of the heavy residual oil. The predictive equations are based on three easily measured bulk properties including refractive index, specific gravity and the Watson K factor.
