The RAX series paraxylene (PX) adsorbents RAX-2000A and RAX-3000, are developed by the Sinopec Re- search Institute of Petroleum Processing (RIPP) and manufactured by the Sinopec Catalyst Company. Performance test of RAX-2000A showed that the average purity of the PX product reached 99.81%, with an average PX yield of 98.6% per pass. The new generation of PX adsorbents, RAX-3000 not only retains most advantages of the adsorbent RAX-2000A, but also has higher selective adsorption capacity by at least 8%. The actual unit production capability of the adsorbent RAX- 3000 was increased by about 18%. The RAX series PX adsorbents exhibited good adaptability to unfavorable feedstock containing high ethyl benzene (EB) fraction besides their better mechanical strength. Preliminary test results indicated that compared to the adsorbent RAX-2000A, the A/Fa and D/F relating to the adsorbent RAX-3000 were notably decreased due to the hi^her selective adsorotion canacitv of the adsorbent RAX-3000. 展开更多

Novel porous aromatic frameworks(PAF-53 and PAF-54) have been obtained by the polymerization of amino compound(p-phenylenediamine and melamine) and cyanuric chloride. They display a certain amount of CO2 adsorption capacity and highly selective separation of CO2/CH4 and CO2/N2 as 18.1 and83 by Henry Law respectively. They may be applied as ideal adsorbents to separate and capture CO2. 展开更多

A novel porous aromatic framework, PAF-8, derived from tetraphenylsilane as basic building unit, was successfully synthesized via Friedel-Crafts alkylation reaction. This PAF material had high thermal stability as well as high surface area (785 m^2 g^-1) calculated from the Brunauer-Emmett-Teller (BET) model. Meanwhile, PAF-8 possessed high performances in gas sorption and especially for CO2 separation. 展开更多
