The GM may allow a properly discovered alchemist's bomb to be used as a trap's effect, but doing so is likely not worth the trouble
The rules don't cover this. Nevertheless, a GM may allow an alchemist (or similar bomb-tosser, like a rogue with the third-party archetype bomber) to replace the typical damage-dealing effect of an existing trap with an alchemist's bomb.
Rather than making the typical Disable Device skill check to disable such a bomb-that's-now-a-trap-effect, disabling this trap should probably require making a successful Disable Device skill check at the DC of the discovery delayed bomb (DC = 10 + the alchemist's level + the alchemist's Intelligence modifier).
This is really complicated, though, and probably not worth the trouble. In addition to lugging around or building in place whatever mechanism the GM deems necessary for accommodating the alchemist's bomb, the nature of delayed and remote bombs means another such bomb-that's-now-an-effect-in-a-trap renders the first inert. Hence, it's not as though the alchemist could single-handedly create a mine field or something. Further, in this case, the short duration of the remote bomb's existence (maximum 1 min./level!), the small area affected by any bomb's splash damage, and the comparatively minor amount of any bomb's splash damage make alchemist's bombs an unusually difficult choice for a proximity-triggered trap.
(Also note that to manually detonate early a bomb modified by the discovery remote bomb mandates not a skill check but an Intelligence check (DC 20 +1 per 10 ft. between the alchemist and the bomb). That means even if the alchemist is willing to be right next to the bomb when it explodes, it's easy to fail this check, making even manual activation of such a trap frequently a failed strategy.)
So this GM would probably adjust the CR of a trap incorporating an alchemist's bomb, depending on the alchemist's level, down by 1 or 2. Were I GM, I'd urge a player wanting to do this to find another method creating an explosive effect in his traps besides a fragile, limited-duration, tricked-out alchemist's bomb.
