HOUSTON, July 11 (Reuters) - Marathon Petroleum MPC.N plans to restart a diesel-producing Ultracracker over the weekend at its 631,000 barrel-per-day Galveston Bay Refinery in Texas City, Texas over the weekend, people familiar with plant operations said on Friday.

The 60,000-bpd Ultracracker was shut on Wednesday by a compressor failure, the sources said.

Marathon spokesperson Jamal Kheiry declined in an email on Friday to discuss operations at the Galveston Bay Refinery, which is the second largest by capacity in the United States.

The Ultracracker uses hydrogen in the presence of a catalyst under high heat and pressure to produce diesel from gas oil.
