So much mystery involved here! You're making everyone guess at the
situation by not identifying the key. I understand you might have
reasons for this caginess, but please realize that your reluctance to
spell out the details of the situation makes this process take much more
of your time and of the time of other people on this list.
You might not be aware that keyservers don't check the correctness of
any of the cryptographic material placed on them. So it's possible to
upload something that looks like a revocation certificate but would be
rejected by any reasonable OpenPGP client implementation, since it would

I understand your hesitation to import the revocation certificate to
your public keyring, though you can probably clean it up with some of
the subcommands of gpg --edit-key .
Alternately, you could create a new GNUPGHOME directory and work
temporarily from that.
mkdir -m 0700 ~/tmpgpg
... do your work here, you'll start with an empty keyring ...
rm -rf ~/tmpgpg

No, you could also just fetch the key from the keyserver via http, and
feed it to gpg --list-packets directly. Here's me doing that with my
own key (you'd need to replace the long keyid with the keyid you care
wget -O- \
| gpg --list-packets \
however, importing it into a gpg keyring is probably a better idea,
since it would let you verify whether the revocation certificate is valid.
