Transiting through Beijing on two separate occasions,do I qualify for the 72 or 24 hour transit visa

I am arriving to Beijing at 5:05 AM, and will switch airlines for a flight leaving at 6:30 PM. I will then return back to Beijing a week later, arriving at 2:55 AM, and departing at 1:10 AM the next day (8 hours and 20 minute layover). Do I qualify for either of the visas?
