Name for the refinery process of breaking down heavier, larger, and more complex hydrocarbon molecules into lighter and simpler ones. Cracking is employed primarily to increase gasoline and other light product yields, and is accomplished in several ways
A refining process under which heavy molecular weight hydrocarbons are broken up into light hydrocarbon molecules by the application of heat and pressure, with or without the use of catalysts, to derive a variety of fuel products.
The process of breaking down large molecules of oil into smaller ones. When this process is achieved by the application of heat only, it is known as thermal cracking. If a catalyst is used as well it is known as catalytic cracking. It is known as hydrocracking if the catalytic process is conducted in a hydrogen atmosphere. Cracking causes molecular decomposition and recombination to produce a range of more useful base chemicals.
The act of breaking into a computer system.
process by which hydrocarbons are refined by modification of the molecular structure using heat, pressure and, sometimes, a catalyst
the controlled process by which large molecules are broken down into smaller molecules. (see catalytic cracking, thermal cracking)
To copy commercial software illegally by breaking (cracking) the various copy-protection and registration techniques being used. Crackers are looked down upon by real hackers and they are the ones seen on the news for causing billions of dollars in damages. Cracking is illegal and will not be tolerated on our servers.
the refinery process in which large, heavy, complex hydrocarbon molecules are broken down into simpler and lighter molecules in order to derive a variety of fuel products.
A refining process involving decomposition and molecular recombination of organic compounds, especially hydrocarbons obtained by distillation of petroleum, by means of heat, to form molecules suitable for various uses such as motor fuels, solvent or plastics. Cracking takes place in the absence of oxygen.
the process whereby heavy molecules of naphtha or petroleum are broken down into hydrocarbons of lower molecular weight (especially in the oil-refining process)
Refining process in which large molecules are broken down into smaller molecules. Cracking takes place to some extent whenever high molecular material is heated strongly, but is increased by catalysts.
It is related to the physical condition of paint film. It is manifest in coatings by a break extending through the paint to the surface. The break should be called a “crack” if the underlying surface is visible. The evaluation terms of cracking degrees are “slight” “definite,” and “bad.
breaking into a network without authorisation, but without intending to damage or destroy them. For example, a cracker may crack into a system to find out its weaknesses.
Breaking up of the coating film. Varying in size from very fine cracks (Crizzle) to very large cracks (Alligatoring). Usually penetrates the entire film thickness.
Splitting or disintegration of a powder film with breaks penetrating through to the substrate. Crazing Fine, random cracks or fissures in a paint film, caused by shrinkage.
The severe breakdown of internal cohesive forces of a sealant either during cure or afterward, as a result of excessive stress. Two typical examples are side and center cracking in an expansion joint. Shrinkage upon curing of elongation can build up excessive stress either at the center of the joint or near the center of the joint causing severe failure. (See " Crazing")
Coating defect: splitting of a coating film as a result of aging, formation of internal stresses or deformation of substrates. See Crazing
The splitting of a dry paint or varnish film, usually a result of aging or movement of the substrate. Different forms are hair-line cracking, checking, grain cracking, or crocodiling.
The breaking down of long-chain hydrocarbon molecules into smaller molecules.
Breaks or splits in the paint's surface.
the process of breaking down larger molecules of hydrocarbons into smaller ones. When this is done by heating the oil it is known as ‘thermal cracking'. If a catalyst is used it is known as ‘catalytic cracking'.
The conversion of large hydrocarbon molecules into smaller ones.
Separations in the topcoat film before or after baking. Cracking can be caused by shrinkage of the paint film during the bake cycle, swelling of the sealer after the topcoat has started to cure, or sliding of the uncured paint film on the uncured sealer due to incompatibility.
Cracking can mean to break into a computer system, to run an attack on a password database or remove copy protection from software.
The splitting of a dry paint film, usually the result of aging. This includes hair cracking, checking, crazing, and alligatoring (crocodiling).
Breaks in a coating that extend through to the underlying surface.
Splitting of a coating film, usually as a result of substrate movement or aging.
The splitting of a dry paint or varnish film, usually a result of aging or movement of the substrate. Different forms are hairline cracking, checking, crazing, grain cracking, or alligatoring.
The act of breaking an encrypted data string such as a system password. Cracking returns the encrypted string to clear text so that it may be read more easily.
means the process of breaking down the large, heavier and more complex hydrocarbon molecules into simpler, lighter molecules.
Advanced state of checking or crazing whereby the breaks in the film are so deep as to expose the underlying surface.
Thermal decomposition of complex hydrocarbons into simpler components.
Breaks in the paint film wide enough to expose the underlying surface.
Cracking is the breaking down of large hydrocarbon molecules into smaller, more useful hydrocarbon molecules by vapourizing them and passing them over a hot catalyst. Useful products from air
Splitting of a paint film usually as a result of aging. Fracture of a metal in a brittle manner along a single or branched path. It can also be caused by subsurface expansion under a brittle topcoat.
The breakup of heavy petroleum molecules into shorter ones through the application of heat and pressure or catalysts.
The process of breaking down the larger, heavier and more complex hydrocarbon molecules into simpler and lighter molecules, thus increasing the gasoline yield from crude oil. Cracking is done by application of heat and pressure, and in modern time the use of a catalytic agent.
The type of paint failure characterized by breaks in irregular lines wide enough to expose the underlying surface.
The production of lighter oils by breaking down heavy oil molecules. This process increases the yield of gasoline from crude oil.
Surface breaks or fissures due to excessive strain or exposure to adverse environmental factors.
Sharp breaks or fissures in rubber surfaces resulting from excessive strain or exposure to adverse environmental factors.
1. The breaking down of heavier hydrocarbons by heat and pressure or by catalysts into lighter hydrocarbons of lower molecular weight, for example gasoline from petroleum. 2. Paint defect brought about by improper material mixtures.
In petroleum geology and chemistry, cracking is the process whereby complex organic molecules (e.g. kerogens or heavy hydrocarbons) are broken down into simpler molecules (e.g. light hydrocarbons) by the breaking of carbon-carbon bonds in the precursors. The rate of cracking and the end products are strongly dependent on the temperature and presence of any catalysts. Cracking is also known as pyrolysis.
