Comparing hydrocracking models: Continuous lumping vs. single events

Deactivation kinetics of individual C6–C9 aromatics' generation from methanol over Zn and P co-modified HZSM-5

“…Additionally, when feeding methanol alone, how methanol is converted into olen is still contentious, especially the initial formation of olen. Some literatures 37,38 employed single-event method to establish the micro-kinetic models for MTH process so that the reaction network is simplied into limited number of types of steps, but the model is too complex for process modelling.…”

Development of (γ-Al2O3-Zeolite Y)/α-Al2O3-HPCM Catalyst based on Highly Porous α-Al2O3-HPCM Support for Decreasing Oil Viscosity

“…The second approach is to add extraneous hydrogen. This is hydrocracking [3,6]. It allows a significant increase in the yield of light distillates, but requires a large amount of hydrogen and a substantial investment, hence it is a costly process.…”

Kinetics and reactor modeling of the conversion of n-pentane using HZSM-5 catalysts with different Si/Al ratios

“…[29][30][31][32] Lump-based kinetic models offer the possibility of predicting the evolution of the catalyst performance with time in a computationally cheap way, by sacrificing the accurate thermodynamics consideration required in some microkinetic techniques. 33,34 These models can however provide enough mechanistic information when the steps of the lump reaction scheme are well related to the different stages of the reaction mechanism. 24 These premises would lead to a rational design of reactors, such as isothermal packed bed reactors that are the most used configuration for kinetic studies on other widely reported catalytic processes as MTO 35,36 or Fischer-Tropsh.…”
