The jet, which used a palm oil biofuel made by China Petroleum and Chemical Corp, or Sinopec, Asia’s largest oil refiner, flew for 85 minutes after taking off from Shanghai Hongqiao International Airport.

Liu said he performed several extreme maneuvers, including diving above 12,000 meters, but found no significant difference between the Sinopec biofuel and gasoline. The plane’s left fuel tank was filled with gasoline to allow him to compare.

“The performance of the biofuel during the takeoff was powerful,” the pilot added.

Sinopec is the first company in China to master the technology of turning palm oil and waste cooking oil into jet biofuel.
