There is not much in the archives on using portables on CDs to prevent removable media from becoming infected. Is there a complete list of portables that function on CDs? To clarify, I do not mean live Linux CDs that need to be booted. I mean portable apps on CDs on public computers that I cannot change the boot sequence in the BIOS to enable them to boot to an USB or CD-ROM.

I understand your concern.
The quickest answer to your question would be to get some RW CDs, put the portable apps you use on it and see if they work.

I would suggest running the apps on a PC first so that any configurations are done before burning.

Many of the individual app pages have instructions on running from CDs:
https://portableapps.com/support/libreoffice_portable#cd
https://portableapps.com/support/firefox_portable#cd
https://portableapps.com/support/gimp_portable#cd
https://portableapps.com/support/thunderbird_portable#cd
are just a few - unfortunately, there's no central list, so you need to look through all the ones you want to use.
However, the common theme to all of these is that you need to run them once on the PC, just as Lurking Biohazard said.
I made this half-pony, half-monkey monster to please you.
