The process uses conventional catalysts and operates under standard hydrotreating conditions approximately 550680f, and from about 1,200 psi for ultralowsulfur diesel fuel ulsd to 2,000 psi for hydrocracking. Hydrocracking and hydrotreating process technology. This process employs hydrogen gas to improve the hydrogencarbon ratio in the cracked molecules and to arrive at a broader range of end products, such as gasoline, kerosene used in jet fuel, and diesel fuel. In hydrocracking, the base oil feed flows over a highactivity catalyst bed at temperatures above 650f and pressures above 1,000 psi.

Basically, there are two types of hydroprocessing as hydrocracking and hydrotreating. It discusses hydrocracking processes and hydrocracking technology in catalytic dewaxing, resid upgrading, and fluid catalytic cracking feedstock improvement. Hydrotreating is the reaction of organic compounds in the presence of high pressure hydrogen to remove oxygen deoxygenation along with other heteroatoms nitrogen, sulfur, and chlorine. This is an established and reliable method for transforming low value heavy oil fractions into higher value products.
