What is the catalytic reforming of oil? What is the purpose?
May 10, 2018


Catalytic reforming: in the case of catalyst, the process of rearranging hydrocarbon molecular structure in gasoline distillate into new molecular structure is called catalytic reforming.

One of oil refining process, heating, hydrogen pressure and the presence of catalyst, make the light gasoline fraction obtained crude distillation (or naphtha) into a high octane number gasoline rich in aromatic (reforming gasoline), and the by-product process of liquefied petroleum gas and hydrogen.

The modified gasoline can be used directly as the blending component of gasoline, and also can be used to extract benzene, toluene and xylene through aromatics extraction.

The byproduct hydrogen is an important source of hydrogen for refinery hydrogenation, such as hydrogenation and hydrocracking.

The catalytic reforming is to rearrange the hydrocarbon molecular structure and produce a large amount of hydrogen.

It can be seen that it is a complicated distillation process.

Catalytic cracking and catalytic cracking is under the action of catalyst, make macromolecular hydrocarbons (carbon chain is longer) is decomposed into less carbon chain hydrocarbon, it aims to produce high octane number gasoline, oil product fractionation of long chain hydrocarbon fracture into ethylene, toluene and xylene and other chemical raw materials, which is the petrochemical production process, the principle is different components in oil to the boiling point is not the same, such as propylene short chain hydrocarbon, or benzene processing, cracking is a depth of cracking.

Catalytic reforming is an important secondary process in petroleum processing, which is a physical process, which is higher than cracking.
