Naphtha adsorption separation technology
Thread Content
Hello everyone, have you heard of naphtha adsorption separation technology? It is said that it can separate normal and isomeric alkanes. I wonder how things are developing now?
Where did you see it? Let’s share the information!

Naphtha components mainly include n-paraffins and isoparaffins, and can be used as feedstocks for olefin cracking or reforming. N-paraffins have good cracking properties but low aromatization capacity； Heteroalkanes have poor cracking properties, but good aromatization effects. If naphtha is separated solely based on its boiling range for use in cracking or reforming units, the normal and isomeric hydrocarbons contained within it cannot be utilized to the fullest extent. Following the principle of \"use aromatics where appropriate, and use ethylene where appropriate,\" normal and isomeric hydrocarbons can be separated using the pore sizes of molecular sieves: normal hydrocarbons are used for cracking to produce light olefins, while isomers are used for reforming to produce aromatics, thereby maximizing their value.
Are there any existing industrial examples?
Hello, which company are you from?
Are there any obvious advantages over separating it from naphtha? Are the operating costs low?
Molecular sieve dewaxing is used for naphtha, and it is a highly mature technology.
