Kinetic study of catalytic cracking of heavy oil over an in-situ crystallized FCC catalyst

Mathematical modelling of catalytic cracking riser reactor

“…A large number of research is dedicated to mathematical modelling of catalytic cracking with different detailing of hydrocarbons conversion scheme (depending on the required predictive power) considering with the catalyst deactivation [17][18][19][20][21][22][23][24][25][26][27].…”

A Novel FCC Catalyst Based on a Porous Composite Material Synthesized via an In Situ Technique

“…Due to diffusion limitations on chemical reactions and mass transfer, many approaches for overcoming this challenge and improving transport in microporous zeolite have been developed. [1][2][3] Zeolite Y can be prepared using a conventional gel synthesis method or in situ crystallization. In the latter synthesis technique, the active components are crystallized into the matrices, which enhances the thermostability of the FCC catalyst compared to the former.…”

Quantitative correlations of cracking performance with physiochemical properties of FCC catalysts by a novel lump kinetic modelling method

“…23 The catalyst property-included lump 24 kinetic model was proved to be 25 effective and reliable. 26 Application of lump kinetic model 27 was broadened in the field of catalyst 28 selection and design.…”

The differential equations of the six-lump kinetic mod-313 els were solved using experimental data at 460, 480, 500 and 314 520°C by a Matlab program which was compiled according to 315 fourth order Runge-Kutta algorithm and the least square method.…”

“…The microactivities of those coked cata-286 lysts were measured by microactivity test and the relative activi-287 ties to those of new catalyst were determined. In the present 288 study, a and b were determined by nonlinear fitting between coke 289on catalyst and relative activity[24].…”
