- n. A process by which the hydrocarbon molecules of petroleum are broken into simpler molecules, as of gasoline or kerosene, by the addition of hydrogen under high pressure and in the presence of a catalyst.
Wiktionary
- n. organic chemistry the production of high-octane petroleum fuel and kerosene by hydrogenating large or complex hydrocarbons and then cracking them.
- v. present participle of hydrocrack.

Examples
“First the bulky hydrocarbon chains are broken into smaller ones in a process called hydrocracking; upgraders may also remove carbon to produce the smaller chains along with coke.”
“Sulphco says ultrasound waves make it easier for oil to react with catalysts, removing the need for the very high temperatures and pressure that other processes, such as hydrocracking, use to break down the oil molecules.”
“Both Eni and UOP say that their slurry hydrocracking methods will collect contaminants for use in other processes, such as making cement and steel.”
“Heavy to Light One method that has been around for decades, known simply as hydrocracking, is becoming increasingly popular because it allows refiners to produce more diesel, which is in high demand, using some sludge, though not the thickest part.”
“But the process, known as slurry hydrocracking, still hasn't been widely tested on the massive scale at which the refining industry operates.”
“UOP, whose slurry hydrocracking technique is based on technology developed by Natural Resources Canada, the natural-resources department of Canada's government, says it is in talks with several refiners and expects to license the technology soon.”
“A parallel slurry-hydrocracking method developed by UOP, a Des Plaines, Ill. -based division of Honeywell International Inc., makes the catalysts easier to replace than when they sit in a filter, UOP says.”
“Slurry hydrocracking is similar to this process, but can break down the thickest part of the sludge.”
“It also owns a distillate hydrocracking unit with 68,000-barrel-a-day capacity and an interest in the Massvlatke Olie Terminal in Rotterdam, one of the world's largest oil terminals.”
“It is also used in large quantities in methanol production, in hydrodealkylation, hydrocracking, and hydrodesulfurization.”
