In end-customer application you can find activated carbon and silica perls mixed together to benefit from the different adsorptions capabilities.
If you operate a specific treatment with a rated activated carbon, you should know what's in it. It could be that you got a wrong batch/grade change or it comes naturally with the grade and you never noticed the silica before.

A far fetched explaination would be to have had some silica perls to keep the AC dry during transport/storage, and they were not removed - I don't think that plausible however.
