Catalyst regeneration techniques in naphtha reforming: Short review

A study on naphtha catalytic reforming reactor simulation and analysis.

A naphtha catalytic reforming unit with four reactors in series is analyzed. A physical model is proposed to describe the catalytic reforming radial flow reactor. Kinetics and thermodynamics equations are selected to describe the naphtha catalytic reforming reactions characteristics based on idealizing the complex naphtha mixture by representing the paraffin, naphthene, and aromatic groups by s...

Heterogeneous Catalyst Deactivation and Regeneration: A Review

Deactivation of heterogeneous catalysts is a ubiquitous problem that causes loss of catalytic rate with time. This review on deactivation and regeneration of heterogeneous catalysts classifies deactivation by type (chemical, thermal, and mechanical) and by mechanism (poisoning, fouling, thermal degradation, vapor formation, vapor-solid and solid-solid reactions, and attrition/crushing). The key...

A Decision Support System for consumption optimization in a naphtha reforming plant

In a naphtha distillation process, the natural objective is to perform an entire process maximization of the production rate while meeting required product qualities by searching for an optimal operating condition by manipulating the operating variables. The objective of this paper includes performing an energy process optimization. Not only is an adequate production rate met with the required ...

State assignment techniques — short review

The task of the (near)optimal FSM state encoding can be generally formulated as assignment of such binary vectors to the state symbols that the resulting binary next-state and output functions can be efficiently implemented with a given implementation technology. It is therefore clear why the evolution of state encoding algorithms is intimately related to the evolution of the implementation pla...
