1. Catalytic purification and hydrocracking are together known as hydroprocessing. 2. Such zeolites are used in cracking and hydrocracking catalysts. 3. This latter process is known as hydrocracking . 4. Hydrocracking breaks big molecules into smaller ones using hydrogen while hydrogenation adds hydrogen to molecules.5. This process also generates hydrogen, which fuels the refinement of extracted bitumen through hydrocracking . 6. Hydrocracking breaks larger molecules into smaller ones using hydrogen while hydrogenation adds hydrogen to molecules.7. Traders said Tosco had to shut down a hydrocracking unit that makes gasoline and diesel fuel. 8. Present U . S . use of hydrogen for hydrocracking is roughly 4 Mt per year. 9. Vegetable oil refining is a process to transform vegetable oil into fuel by hydrocracking or hydrogenation. 10. The hydrocracking of paraffins is the only one of the above four major reforming reactions that consumes hydrogen.
