Is 72 hour VISA Free possible in Beijing airport

Hi! I am from Brazil and living in India. I am going to Hong Kong and then I'll be flying from Hong Kong to BJ on Nov 18th arriving in BJ at 00:10 Nov 19th, then flying from BJ to Bangkok on Nov 21th at 20:15. These are separate airline confirmed e-tickets. Can I get in Capital Airport this 72hr VISA?
