Hydrocracking Process

Get in touch


Hydrocracking is a process that breaks down complex hydrocarbon molecules into simpler ones by using a catalyst and an elevated partial pressure of hydrogen gas. This is an established and reliable method for transforming low-value heavy oil fractions into higher-value products. This is generally a more demanding hydrotreating process but is rapidly emerging as the principle conversion technology to maximize diesel yield due to its ability to produce ultra-low sulfur diesel (ULSD). Hydrocracking is normally facilitated by a bifunctional catalyst capable of rearranging and breaking hydrocarbon chains as well as adding hydrogen to aromatics and olefins to produce naphthenes and alkanes. Major products from hydrocracking are jet fuel, diesel, relatively high-octane rating gasoline fractions and LPG. All of these products have a low content of sulfur and contaminants.
