Position of P-Xylene

PX belongs to a kind of C8 mixed aromatics, which has 4 isomers, namely OX(ortho-xylene), MX(meta-xylene),  PX(para-xylene), and EB(ethylbenzene). Limited by the thermodynamic balance,  the OX content takes a large portion of C8 mixed aromatics at 41%-45%, while the PX content, which has the largest industrial demand, takes only about 20%. Many world-scale projects are being configured to produce maximum volumes of chemicals. In order to maximize the production of PX, technologies such as toluene disproportionation, trans-alkylation, and isomerization are usually used in industry to increase the production of PX.

In modern daily life, PX derivatives are everywhere. The polyester and polyester fiber in clothes are the downstream products of PX. The telephones, mobile phone cases, mineral water bottles, computer shells, capsules, curtains, and cameras around us are all related to PX. The economic and social development of modern society is inseparable from PX. The production and processing of PX for food, clothing, housing, and transportation together build a “golden industrial chain”.


The Feature of Jalon PX adsorbent

Jalon PX adsorbent can be adsorbed inside the channels and separated from other xylenes by its different affinities toward the framework structure.
Jalon PX adsorbent is characteristic of high adsorption capacity, good adaptability to feed, and better mechanical strength, which can be applied to any SMB separation process.


Experienced Engineer Team

Jalon respects knowledge and talent, and puts more attention into absorbing the R&D teams. Now Jalon has 2 analysis departments, 1 laboratory, 1 pilot plant for raw powder, and 1 for granulation. Over 3% of the company’s total operating income is put into R&D.

Backed by Provincial Research Center

Jalon has established solely and jointly institutes such as Henan Adsorption Molecular Sieve Engineering Technology Research Center, the Production-Education-Research Joint Laboratory of Porous Materials for Carbon Capture and Low Carbon Adsorption&Separation, etc.

Customization Capability

By 2022, the production capacity of synthetic zeolite powder is 41,000mt, activated zeolite powder 3,000mt, finished molecular sieve 42,000mt, activated alumina 5,000mt. The adequate capacity offers more flexibility in product customization.

Strict Quality Control

Strict quality control covers the whole production process from raw material purchasing, semi-finished product tests, to quality inspection. Meeting the requirements of clients is always Jalon’s priority.
