The plug flow reactor (PFR) is an important model used in chemical engineering. It allows for the development and optimization of catalytic processes. It enables engineers to determine and validate the kinetics of chemical reactions and calculate the reactor’s volume necessary for designing efficient processes.

Since catalysts are integral to almost all energy-related processes, the study of heterogeneous reactions plays an important role in advancing the world’s energy paradigm and developing renewable energy technologies.

The synthesis of organic and inorganic compounds makes extensive use of heterogeneous catalysts. It makes it possible to manufacture products faster and at a larger scale. The following fields make extensive use of heterogeneous catalysts:
–       synthesis of organic and inorganic chemicals.
–       energy production.
–       environmental protection.

In heterogeneous catalysis, a solid material serves as a catalyst that adsorbs reactants, holds them close, and facilitates the release of products. To model these reactions, the Langmuir–Hinshelwood–Hougen–Watson (LHHW) model is the preferred choice.

The Spoken Tutorial project presents an example of a DWSIM simulation of heterogeneous catalytic reactors for hydrogen production. The video emphasizes the importance of solid materials acting as catalysts to adsorb reactants, hold them close, and facilitate the release of products.

We like  this video because: 
–        It presents highly relevant content in a compact form.
–        Has beginner-friendly content.
–        Presents the heterogeneous catalysis simulation in detail.
–        Highlights the relevance and the complexity of modeling Langmuir–Hinshelwood–Hougen–Watson (LHHW) kinetics.
