ENGR 3447 Adsorption and Membrane Processes

| March 14, 2016

1) Activated clays are generally used for one-off applications to adsorb organic substances (i.e., the adsorbent is not recycled). What is it about them that make them suitable for this type of application? Describe two examples, other than cat litter, of their use as an adsorber in products utilized in environmental protection and/or clean-up.
2) Zeolites are used to adsorb a wide range of solutes from vapour and gas streams. What is it about their structure that makes them suitable for selective adsorption? Describe why and how they are used in one industrial process or product. If the used (spent) zeolite is regenerated for reuse, describe how it is, but if not, discuss why not.
Your report should be fully referenced within the text, including any pictures or diagrams used. It should start with the Title and then an Abstract (no more than 8 lines). These should be followed by an Introduction and then Sections that cover all the above requirements.
Finally, include a Conclusion section that provides an overall discussion of the key points arising from the entire report. The Conclusions should be no more than one page. Also make sure you include at the end of the report a list of all References used in the text.
For a guide on how to use references in the text and compile a reference list, refer to the separate Assignment Guidelines loaded up on D2L. On-line encyclopedias, such as Wikipedia, are not acceptable as a reference – you must quote the original source (e.g., journal article, book, technical report, company website etc.).
Any blatant copying of other work, such as cutting and pasting of text from web pages, will be penalized. Late submissions will be also penalized.
Please place a hard (paper) copy of your report in my mail slot in the Engineering School Office, on or before Monday 22nd February 2016. Soft copies (e.g., email attachments) cannot be accepted.
