Hydrocracking is a catalytic chemical process used for deep oil processing 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. The process takes place in a hydrogen-rich atmosphere at elevated temperatures (260 – 425 °C) and pressures (35 – 200 bar).
By the hydrocraking process heavy oils can undergo hydrogenation, isomerization and cracking reartions in the presence of the catalyst and hydrogen for increasing hydrogen to carbon ratios of the products. The hydrocracking process, in fact is a combination of hydrotreating and catalytic cracking processes. On one hand, heavy oils can be converted by hydrocracking into light oils such as gasoline, jet fuel and light diesel oil. Meanwhile no great amounts of coke can be formed. By this process the sulfur, nitrogen and oxygen non-hydrocarbon compounds can be removed and the olefins can be saturated by hydrogenations.
Basically, hydrocracking plants are capable of processing a wide variety of feedstocks of different characteristics to produce a broad range of products. They can be designed and operated to maximize the production of a gasoline blending component (called hydrocrackate) or to maximize the production of diesel oil.
SINOCATA offers hydrocracking catalyst to meet the high jet/diesel yield and especially meeting the high Cetane number and low sulphur specification.
