To objectify something is to “present [something] as an object,” (even when it’s not an object).

Here’s an example provided by Wordnet:

“Pornography objectifies women”

Here’s an example provided by Dictionary.com:

“Because we have objectified animals, we are able to treat them impersonally.”

By the way, I chose the word, “objectify,” because it has the same suffix as “personify,” (with respect to your question), and their meanings seem to be opposites.

(Is this the word you’re looking for?)

from Websters…

\In*an`i*ma”tion\, n. Want of animation; lifeless; dullness.

Anthropomorphism is NOT correct.

I also saw this but no real credible definition anywhere other than adding a prefix……

“anti-personification”
