Chicago gasoline and diesel strengthened against futures on plans for Marathon Petroleum Corp. to shut units at its Kentucky refinery.
Ultra-low-sulfur diesel gained 1.25 cents to 3.75 cents a gallon above futures on the New York Mercantile Exchange at 4:29 p.m., the strongest level since June 14. Conventional, 85-octane gasoline, or CBOB, traded at a 3.5-cent premium to Nymex futures after trading at a discount Sept. 13.
Two state filings showed that Marathon’s Catlettsburg, Kentucky, refinery was scheduled to shut a distillate desulfurization unit today, a hydrogen system tomorrow and a crude unit and several others on Sept. 23. A fluid catalytic cracker was expected to shut Sept. 15 for 45 days of work, a person familiar with the refinery’s operations said last week.
Jamal Kheiry, a spokesman for Marathon in Findlay, Ohio, declined to comment on the maintenance plans.
The Catlettsburg refinery, in northeastern Kentucky on the Big Sandy River, has a capacity of 240,000 barrels a day. The plant processes a wide range of both sweet and sour crude oils and distributes products by pipeline, barge, truck and rail, according to Marathon’s website.
The 3-2-1 crack spread in Chicago, a rough measure of refining margins based on West Texas Intermediate oil in Cushing, Oklahoma, was little changed at $12.57 a barrel.
