New Grad CRE files posted

Since we are currently teaching our graduate reaction engineering course, we have added some new files. See the Resources link, Grad CRE Notes, and these new files:
* Surface kinetics – the Steady-State Approximation applied for unsteady-state reactors
* Reaction-Diffusion blackboards 1
* Reaction-Diffusion blackboards 2
* Reaction-Diffusion blackboards 3

Looking for PureWaterLab?

We closed our PureWaterLab web site. The site only had one web page and directed users to to download the software. We are planning to consolidate all of our work at this Reactor Lab site. remains active for now and is the site for download of PureWaterLab and Reactor Lab’s English version.

Chemical Reaction Engineering Notes posted

See the RESOURCES tab above. Select the section “CRE Notes.” On that page there is a link to my Chemical Reaction Engineering (CRE) Notes.

The organization of these notes differs from most textbooks on CRE. These notes consider only Batch and Semi-Batch reactors at the start. Only after all the major topics (e.g., stoichiometry, change in gas density, thermal effects) are covered do they proceed to PFRs and CSTRs.

Why this organization? Some students told me that they got confused when they encountered a new topic (e.g., thermal effects) and lectures switched back and forth between the different types of reactors. I can understand their concern. I now think it is better to stick to Batch reactors until students learn them very well before switching to other reactors.
