A kind of separation method of hexane isomer

Abstract

The invention discloses a method for separating hexane isomers, which comprises contacting the mixture of hexane isomers with an adsorbent for adsorption separation; the general structural formula of the metal organic framework material is M 3 [T(CN) 6 ] 2 , M selected from Zn 2+ or Ni 2+ , T selected from Co 3+ , Fe 3+ and Ir 3+ one or more of. The metal frame material used in the method of the invention has good separation effect, simple material preparation process, low cost, good regeneration and repeatability, and has broad industrial application prospects.

Description

A kind of separation method of hexane isomer technical field The present invention relates to chemical engineering and technical field, be specifically related to a kind of separation method of hexane isomer. Background technique Separating hexane isomer, improving gasoline octane number (RON), is a very important unit operation in petrochemical industry. do. This unit operation has important implications for public health as it reduces the amount of octane currently used to increase gasoline octane And the use of added aromatic compounds. Large quantities of hexane isomers are produced during catalytic isomerization reactions, including at least 10% straight chain, approximately 50% monobranched and 40% dibranched paraffins. The higher the degree of branching of the alkane, the higher the octane number. High, for example, monobranched paraffin 3-methylpentane (3MP; RON 75) and dibranched paraffin 2,2-dimethylbutane (22DMB; RON 94) has a much higher octane numbe...

Problems solved by technology

[0005] Therefore, in view of the current porous materials, including molecular sieves and metal-organic framework materials, which have low selectivity for the separation of single-double branched hexane isomers, it is urgent to develop new separation materials and separation methods to achieve single-double branched hexane isomers.
