Помогите, пожалуйста, перевести слово crack в следующем контексте:

Моге broadly, relatively expensive steps will bе required throughout the refining circuit to rebalance products, resulting in much wider price spreads for аll middle distillates versus fuel oil. At times in 2020, the refining circuit will most likely need to run additional crude to make sufficient compliant marine fuel but will not have the capabllity to completely "destroy" the surplus high sulfur fuels. This will drive high sulfur residual prices low enough to Ье competitive for burning in power generation оп the margin. Diesel and jet cracks will soar. Gasoline cracks will also Ье driven higher. The price of the new 0.5% sulfur fuel will initially Ье close to marine gasoil.

Заранее спасибо за любые варианты!
