Phillips 66 Wood River Refinery in Roxana Hit by Catalytic Cracker Problems

Phillips 66 is experiencing operational issues at its 355,000-barrel-per-day Wood River Refinery in Roxana, Illinois, according to sources cited by Reuters. The problems center on the facility's catalytic cracker unit, a key piece of equipment that converts heavy oil into higher-value products such as gasoline. The Roxana plant, located roughly 15 miles northeast of St. Louis, is one of the largest refineries in the U.S. midcontinent and is operated by WRB Refining, a 50-50 joint venture between Phillips 66 and Cenovus Energy.

Catalytic cracker outages typically reduce a refinery's gasoline and distillate output and can pressure crack spreads in the affected region. The timing draws attention as Phillips 66 had already been drawing fresh investor interest, with analysts noting positive momentum in the stock ahead of the company's next earnings report. Any extended downtime at Wood River would add uncertainty to that near-term outlook.
