Facebook – Can Facebook send a confirmation code to an alternate email not associated with the account

Facebook does not support account merging. You have to manually copy what you want from your old profile, and then delete it.

You should be able to regain access to old account via http://www.facebook.com/#!/help/contact.php?show_form=hack_nologin_access - I've never used this and I don't know what they procedure is however. I guess once you have convinced them your are who you say you are, they will change the account email address, which will let you reset the password as normal.

You may be able to get back into your Facebook account by answering a security question, using an alternate email address listed on your account or getting help from friends. Keep in mind that you'll only see these options if you set them up.
