![]() ![]() Hydrocracking plants are capable of processing a wide variety of feedstocks of different characteristics to produce a broad range of products. The result is that the hydrocracking products are essentially free of sulfur and nitrogen impurities and consist mostly of paraffinic hydrocarbons. Any sulfur and nitrogen present in the hydrocracking feedstock are, to a large extent, also hydrogenated and form gaseous hydrogen sulfide (H 2S) and ammonia (NH 3) which are subsequently removed. īasically, the process cracks the high-boiling, high molecular weight hydrocarbons into lower-boiling, lower molecular weight olefinic and aromatic hydrocarbons and then hydrogenates them. The process takes place in a hydrogen-rich atmosphere at elevated temperatures (260 – 425 ☌) and pressures (35 – 200 bar). Hydrocracking is a catalytic chemical process used in petroleum refineries for converting the high-boiling constituent hydrocarbons in petroleum crude oils to more valuable lower-boiling products such as gasoline, kerosene, jet fuel and diesel oil.
