RIO DE JANEIRO — Eike Batista, an oil and mining tycoon who just years ago was on a quest to use his vast fortune to turbocharge Brazil’s growth, was sentenced to 30 years in prison this week on charges of paying more than $16.5 million in bribes.

Mr. Batista, a flamboyant businessman whose meteoric rise and dramatic fall mirrored the boom-and-bust cycle that has rattled Brazil over the past decade, is among the best-known Brazilians implicated in the corruption scandal known as Lava Jato, or Car Wash.

Federal Judge Marcelo Bretas, who is based in Rio de Janeiro, found that Mr. Batista had bribed Sérgio Cabral, the Rio de Janeiro governor, to secure public contracts.

Judge Bretas sentenced Mr. Cabral, who has been convicted in several other corruption cases, to 22 years in prison, pushing his total prison sentence to more than 120 years.
