Catalytic cracking of heavy hydrocarbons in the presence of hydrogen is known as hydrocracking. The hydrocracking process converts heavy, high-boiling petroleum feedstock into lighter products (naphtha, kerosene, diesel, etc.) or high-quality lubricating oils.
A hydrocracking unit, or hydrocracker, takes gas oil, which is heavier and has a higher boiling range than distillate fuel oil, and cracks the heavy molecules into distillate and gasoline in the presence of hydrogen and a catalyst.
At its core, hydrocracking is a catalytic chemical process used in petroleum refineries to convert heavy oil fractions into more valuable, lighter products such as gasoline, jet fuel, and diesel. It combines the principles of hydrogenation and cracking.
Hydrocracking is 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.
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.
Limitations and Disadvantages of the Hydrocracking Process Before a refinery decides to invest in a hydrocracker unit, a consideration of the advantages and disadvantages of the hydrocracking process must take place. In regards to disadvantages, the primary concern is the capital cost.
A hydrocracker is defined as a catalytic process that converts high molecular weight feedstocks into lower molecular weight products by reacting them with hydrogen, utilizing a bifunctional catalyst that promotes both hydrogenation and cracking.
Hydrocracking is a second catalytic cracking process applied typically to the heavy vacuum gas oil, a sidecut from the vacuum distillation column. When the oil is mixed with hydrogen and passed over a catalyst, the long chain hydrocarbon molecules are broken down into shorter ones.
