NEW YORK - Exxon Mobil Corp has restarted a gasoline-making fluid catalytic cracker at its 503,000 barrel-per-day Baton Rouge, Louisiana, refinery after an unplanned shutdown late last week, traders said Friday.

Several trading sources told Reuters they believe the 120,000-bpd unit is running again after the repairs but they were not sure when it will be back at planned rates. The refinery is the second largest in the United States.

Believe it has (restarted), said one cash oil products trader, seconding views from other market players.

Exxon officials were not immediately reachable for comment.

Early this week, a spokesman for the oil major declined to comment on the reports of the outage, which traders said at the time was caused by a leak in a feed line with the total down time expected to be around five to seven days.
