By rebuttal, I assume that you mean debating. There are several examples of debating in Farenheit 451. A notable example would be the argument between Montag and Beatty. This discussion is interesting is interesting in that Beatty actually uses the books that Montag has come to admire to rebutt Montag's newfound fondness and fascination with books. Beatty quotes many prominent authors and intellectuals, including Sir Philip Sidney and Alexander Pope. Thereby, Beatty argues that books are merely a source of controversy, and that anything written in one book is probably completely contradicted in another book. It is ironic that Beatty, whose job is to destroy books, is so knowledgeable of many works or literature and capable of skillfully debating based on his knowledge.
