XOM Exxon Mobil Corp

ExxonMobil Research and Engineering Company (EMRE) today announced that SK Corporation, the market leader in Group III lubes production and the largest refiner in Korea by capacity, has selected ExxonMobil's industry-leading MSDW catalyst technology for its Ulsan, South Korea lube plant expansion. SK Corporation made a decision to expand capacity and improve yields at their two Ulsan catalytic lube plants.
