Resid FCC reaction model.

Five-lump kinetic model with selective catalyst deactivation for the prediction of the product selectivity in the fluid catalytic cracking process

“…AncheytaJuarez et al [7] followed a different approach in their 5-lump models development, in which they considered the gas oil as one lump, but divided the gas lump into two lumps (liquefied product gas and dry gas). 6-Lump models were developed by Takatsuka et al [8] (including the resid as a separate lump to predict the catalytic cracking of residual oil), and Oliveira and Biscaia [9] (emphasizing in the catalytic cracking of gasoline and paraffinic gas oils). Hagelberg et al [10] expanded the 5-lump model of Ancheyta-Juarez et al [7] to an 8-lump model by dividing the gasoline fraction into paraffins, olefins, naphthenes and aromatics.…”

Kinetics of gas oil catalytic cracking

“…Chemical kinetic modeling of the main reactions is used to improve and predict the FCC process [4][5][6]. More or less complex kinetic models have been presented by many researchers, such as Weekman [7], Lee et al [8], Yen et al [9], AncheytaJuarez et al [10], Takatsuka et al [11], Soares Cerqueira et al [12] and others. These models are of equal kinetic importance as the simpler ones, but they are mathematically more complex.…”

Estimation of the Kinetic Parameters of a Catalytic Cracking Model Case Study

“…Determination of the velocity constants k j o , j=1,...,3 related to reaction velocity are realized by minimization the following objective function (9) where T j exp represents the experimental riser temperature; T j cal (k 1 o ,k 2 o ,k 3 o ) -the temperature calculated with reactor model, for the same values of input data from experimental set j.…”

“…Hagelberg expanded this model in a 8-lump model by dividing the gasoline fraction into paraffin's, olefins, naphthenes and aromatics [8]. For the heavy feedstock's Chiyoda Chemical Engineering and Construction Co. have developed a 6-lump kinetic model, where the feedstock have been divided in two components: residue and heavy gasoil, and the reaction products obtained are: light gasoline, gasoline, gases and coke [9]. Some authors have developed more complex kinetic models, such as 10-lump model [10,11], 12-lump model [13], 13-lump model [14], 19-lump model [15].…”
