Hello I'm exploring the possibility of filtering the induction air of an internal combustion engine through a suitable zeolite to increase its oxygen percentage. I've read the thread on Pressure Swing Adsorbtion and understand that normally air is forced through the zeolite at up to 150kPa but I do not need 95% pure oxygen. Questions I have are: 1 What sort of surface area of zeolite is required per cfm? 2 How long can the zeolite remain effective before it requires to be regenerated? I only need it to last a maximum of 10 seconds. 3 Can it be regenerated by blowing oxygen through it from a high pressure cylinder? If so does it then need protecting from air until required? As I've said I'm not looking for 95% pure, any percentage increase will be beneficial. Any advice please!
