Abstract: The Physical and chemical properties and commercial application are mentioned. The 600kt/a PX plant of an enterprise started in operation successfully at the end of 2013 and has been running smoothly since its start-up. The calibration results showed the the average purity and yield of p-xylene were 99.8% and 98.3% ,respectively, which exceeded the guaranteed value of the technical contract.In the production process, the water balance is controlled between 0.8 and 1.0, which is beneficial to improve the adsorption selectivity. Compared with the data of reference agent, RAX-3000 adsorbent has better properties in raw material adaptability, extreme working conditionsand adsorption capacity.

Key words: adsorbent, para-xylene, adsorption separation, RAX-3000
