A mechanism-oriented kinetic model has been developed with a small CPU requirement which allows the model to be incorporated into a reactor simulation with fluid dynamics and heat and mass transfer. The model achieves a small CPU requirement by lumpi

A stochastic method was devised to transform efficient sets of analytical characterizations into molecular representations of complex petroleum feedstocks. Important structural attributes of petroleum molecules (e.g. number of aromatic rings, number

A thermochemical kinetics-based lumping strategy for modeling the pyrolysis of individual components of heavy hydrocarbon mixtures is suggested. Pyrolysis of a given feedstock is viewed from two perspectives. First, molecules are organized into compo

Mechanism-derived rate laws for kinetically coupled Rice-Herzfeld pyrolysis were used to deduce the form of semiempirical rate laws (SERLs) that nevertheless represent the mechanistic chemistry. These SERLs strike a balance between the CPU demands of

Hondo and Maya vacuum resids and their isolated asphaltenes were pyrolyzed at 400, 425, and 450°C (752, 797, 842°F) for batch holding limes ranging from 20 to 180 minutes. Maltene, asphaltene, and coke product fractions were isolated by a solvent e

The problem of asphaltene precipitation during their thermolysis in a hypothetical inert oil motivated development of a stochastic model of asphaltene structure, reactions, and product identification. This amounted to stochastic construction of 10,00

The model of uniform nonlinear kinetics recently developed for the continuous description of a multicomponent mixture reacting in a batch or plug flow reactor (Astarita, 1989) is applied to the analysis of a continuous stirred tank reactor (CSTR). It
