Hydrocracking is a refining technology that such as hydrotreating falls under the general umbrella of hydroprocessing (Chapter 9: Hydrocracking). The outcome is the conversion of a variety of feedstocks to a range of products and units to accomplish this goal can be found at various points in a refinery ( Parkash, 2003; Gary et al., 2007; Speight, 2014, 2017; Hsu and Robinson, 2017 ) hydrocracking - the process whereby hydrocarbon molecules of petroleum are broken down into kerosene and gasolene by the addition of hydrogen under high pressure in the presence of a catalyst cracking - the process whereby heavy molecules of naphtha or petroleum are broken down into hydrocarbons of lower molecular weight (especially in the oil-refining process Hydrocracking is an important source of diesel and jet fuel Source: Millennium Global, Inc., used with permission. 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 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
Hydrocracking is a catalytic cracking process assisted by the presence of added hydrogen gas. Unlike a hydrotreater , hydrocracking uses hydrogen to break C-C bonds (hydrotreatment is conducted prior to hydrocracking to protect the catalysts in a hydrocracking process) The Hydrocracking (HC) process is able to remove the undesirable aromatic compounds from petroleum stocks producing cleaner fuels and more effective lubricants. In othe Hydrocracking Reactions Many simultaneous chemical reactions occur in hydrocracking. Mechanism of hydrocracking is that of catalytic cracking with hydrogenation superimposed . Catalytic cracking is the scission of a carbon-carbon single bond, and hydrogenation is the addition of hydrogen to a carbon-carbon double bond
Många översatta exempelmeningar innehåller hydrocracking - Svensk-engelsk ordbok och sökmotor för svenska översättningar What is Hydrocracking? Hydrocracking is the process of converting high boiling constituents into low boiling constituents. That means; the reactants of hydrocracking reaction are constituents of petroleum oil having high boiling points, and the products are compounds having low boiling points Hydrocracking.

It is used for feedstock that are difficult to process either by catalytic cracking or reforming Other articles where Hydrocracking is discussed: cracking: automobile and jet fuel increased, hydrocracking was applied to petroleum refining. This process employs hydrogen gas to improve the hydrogen-carbon 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
Unconverted hydrocarbon can then be recycled to the hydrocracking step for further conversion, sent to a second hydrocracking vessel, or sent to another conversion unit as feed (e.g., an FCC). Diesel range material can also be drawn off at the separation steps to maximize diesel production, or it can be processed further (through recycling or second-step hydrocracking) to maximize naphtha. HCat residue hydrocracking technology is based on the in situ formation of a molecularly dispersed catalyst intimately mixed throughout the heavy oil feedstock. Molecular dispersion of the catalyst in heavy oil is achieved by blending an oil-soluble catalyst precursor with a residue feedstock using HTI's proprietary mixing system before the feed preheat system Hydrocracking Technology.

The hydrocracking process depends on the nature and quality of the feedstock and the relative rates of the two competing reactions, hydrogenation and cracking Resid hydrocracker. Also known as: RHCU, H-Oil, LC-Fining, Hycon. The resid hydrocracker upgrades vacuum resid through cracking while injecting hydrogen.This yields a high volume of high-quality diesel and kerosene product. It is similar to the more common gasoil hydrocracker, except that it is capable of running a heavier feed and is more expensive to build and complex to operate
An important sensitivity is the possibility of co-locating the plant with an existing refinery. In this case, the plant consists only of the first three steps: feed prep, fast pyrolysis, and upgrading. Stabilized, upgraded pyrolysis oil is transferred to the refinery for separation and finishing into motor fuels . The hydrogenation increases the yield of gasoline and produces saturated hydrocarbons which do not gum up with time Therefore, hydrocracking of vacuum residue not only allows better product selectivity, but can also produces cleaner fuels. The degree of residue conversion and, consequently, the cost of the process are strongly affected by the amount of low- value by-products produced and the amount of hydrogen required  These multi-functional hydrocracking catalysts allow the recovery of catalyst volumes previously reserved for hydrotreating or demetallization. The high hydrotreating activity demonstrated by of our latest generation of ISOCRACKING catalysts enables hydrocracker operators to achieve their desired conversions at much lower catalyst temperatures
