What is cracking and reforming in the petroleum industry?

Cracking. ... Cracking, in petroleum refining, the process by which heavy hydrocarbon molecules are broken up into lighter molecules by means of heat and usually pressure and sometimes catalysts. Cracking is the most important process for the commercial production of gasoline and diesel fuel.

What is meant by reforming of petroleum?

Reforming is a process designed to increase the volume of gasoline that can be produced from a barrel of crude oil. ... By controlling the temperature and flow rate of the reformer, refinery operators can increase the octane rating of the reformate, but that also has the effect of producing less reformate.

What are the two types of cracking?

Cracking is primarily of two types – thermal cracking and catalytic cracking. Thermal cracking is further categorised into modern thermal cracking and steam cracking. On the other hand, sub-classifications of catalytic methods of cracking are hydrocracking and fluid catalytic cracking.

What do you mean by catalytic reforming?

Catalytic reforming is a process whereby light petroleum distillates (naphthas) are contacted with a platinum-containing catalyst at elevated temperatures and hydrogen pressures ranging from 345 to 3,450 kPa (50–500 psig) for the purpose of raising the octane number of the hydrocarbon feed stream.

What is the process of cracking?

Cracking, in petroleum refining, the process by which heavy hydrocarbon molecules are broken up into lighter molecules by means of heat and usually pressure and sometimes catalysts. Cracking is the most important process for the commercial production of gasoline and diesel fuel.

What conditions are needed for cracking?

Cracking

• Thermal cracking uses harsh conditions like high temperature and high pressure.
• It breaks the alkanes into a high percentage of alkenes and comparatively few alkanes.
• Thermal cracking is done at about 1,000 degrees Celcius and 70 atm pressure.

What is the difference between isomerization and reforming?

Catalytic reforming is the process of transforming C7–C10 hydrocarbons with low octane numbers to aromatics and iso-paraffins which have high octane numbers. It is a highly endothermic process requiring large amounts of energy. ... Isomerization is a mildly exothermic reaction and leads to the increase of an octane number.

Why Hydrogen is used in reforming process?

In many petroleum refineries, the net hydrogen produced in catalytic reforming supplies a significant part of the hydrogen used elsewhere in the refinery (for example, in hydrodesulfurization processes). The hydrogen is also necessary in order to hydrogenolyze any polymers that form on the catalyst.

Why are alkanes reformed?

The reaction produces Branched Alkanes, and so is useful in improving Octane Number. Reforming is the process of increasing the amount of Cycloalkanes and Hydrocarbons containing Benzene Rings, to improve Octane Number. ... This can produce Branched and Cyclic Hydrocarbons and is used to improve Octane Number.

What is the purpose of cracking?

Cracking is a technique used in oil refineries whereby large and complex hydrocarbon molecules are broken down into smaller and lighter components that are more useful for commercial or consumer use. Cracking is a critical stage in the process of refining crude oil.

What are the importance of cracking?

Cracking is important for two main reasons: It helps to match the supply of fractions with the demand for them. It produces alkenes, which are useful as feedstock for the petrochemical industry.

Is steam cracking the same as thermal cracking?

Thermal cracking is currently used to "upgrade" very heavy fractions or to produce light fractions or distillates, burner fuel and/or petroleum coke. Two extremes of the thermal cracking in terms of the product range are represented by the high-temperature process called "steam cracking" or pyrolysis (ca.
