If by published adventures, you're referring to the hardcovers...there's no well defined rule.
An AL Coordinator can (and should) correct me if I'm wrong on this, but the ALPG (p5) states "If you’re playing adventures with multiple episodes (including adventure products like Lost Mine of Phandelver or Out of the Abyss), you won’t be awarded downtime days or renown points until the end of an episode, rather than at the end of each session.". So, it's clear that you're *intended* to get renown and downtime days. Likewise, the DM section (p12) lays out some rough guidelines ("You do not award renown after each session, unless that session is the end of an episode or adventure.")
What we've done is to award 1 renown / 10 downtime days at the point where an episode clearly wraps up (The heading "Conclusion" is what we keyed in on). For example, in Princes of the Apocalypse, we awarded R/DT after each elemental temple. This seems to fit the intent and style of how AL rewards are applied, and matches what the *DM* will get according to ALPG p13.
