What is isomerization

In the field of oil processing, isomerization refers to the process
of converting orthomeric hydrocarbons into isomeric hydrocarbons.
Compared with orthomorphic hydrocarbons, some isomeric hydrocarbons have better
service performance and processing performance.
For example, the octane number after isomerization of n-Rong + alkane and n-hexane will be greatly increased, and n-butane can be used as a raw material for the synthesis of isooctane with high octane value components, and n-butene can be used as a raw material
for the etherification synthesis of methyl right butyl ether (MTBE) after isomerization.
Therefore, the isomerization process as an oil processing process has gradually received attention and developed rapidly
in recent years.

The isomerization process is also a catalytic reaction process, using an acid catalyst, and the acid catalyst is both an isomerization catalyst and a cracking catalyst, how to control the cracking reaction in the isomerization process is a problem
that needs to be considered in the development process of isomerization catalyst.
In recent years, the isomerization process mostly uses hydrogen isomerization to inhibit side reactions
such as coking and cracking in the isomerization process.

At present, the domestic isomerization process is mainly used for the isomerization of C5, C6 n-alkanes, to produce high-octane gasoline components, isomerized gasoline research method octane number up to 95 or so, and octane sensitivity is small, almost no heteroatoms and aromatics, is an excellent high-octane clean gasoline blending component
.
With the continuous improvement of oil cleaning requirements, the isomerization device will be further developed rapidly
