Selective adsorption of paraffins over olefins（mostly C2 and C3） by porous solids could offer tremendous advantages for the purification of olefins, which is, however, challenging as it has stringent requirements on the pore dimensions and pore surface chemistry of the adsorbent. We report here a metal-organic framework（MOF） with novel topology, Y3（μ3-OH）(TCMPB)2(denoted as HIAM-316, TCMPB4-= 1,2,4,5-tetra（4-carboxy-3-methylphenyl）benzene), which shows reversed separation of C2H6/C2H4and C3H8/C3H6simultaneously. The ideal adsorbed solution theory（IAST） selectivities for equimolar binary mixtures of C2H6/C2H4and C3H8/C3H6were calculated to be 1.67 and 1.23 at 1 bar and 298 K for HIAM-316. Its capability of removing paraffines from paraffin/olefin mixtures is validated by breakthrough measurements. Molecular simulations reveal that the preferential adsorption of paraffins over olefins by HIAM-316 may be attributed to the abundant carboxylate oxygen atoms along its channel.

Development and performance evaluation of high temperature resistant strong adsorption rigid blocking agent

As drilling wells continue to move into deep ultra-deep layers, the requirements for temperature resistance of drilling fluid treatments are getting higher and higher. Among them, blocking agent, as one of the key treatment agents, has also become a hot spot of research. In this study, a high temperature resistant strong adsorption rigid blocking agent(QW-1) was prepared using KH570 modified silica,acrylamide(AM) and allyltrimethylammonium chloride(TMAAC). QW-1 has good thermal stability,average particle size of 1.46 μm, water contact angle of 10.5., has a strong hydrophilicity, can be well dispersed in water. The experimental results showed that when 2 wt% QW-1 was added to recipe A(4 wt% bentonite slurry+0.5 wt% DSP-1(filtration loss depressant)), the API filtration loss decreased from 7.8to 6.4 m L. After aging at 240.C, the API loss of filtration was reduced from 21 to 14 m L, which has certain performance of high temperature loss of filtration. At the same time, it is effective in sealing 80-100mesh and 100-120 mesh sand beds as well as 3 and 5 μm ceramic sand discs. Under the same conditions,the blocking performance was superior to silica(5 μm) and calcium carbonate(2.6 μm). In addition, the mechanism of action of QW-1 was further investigated. The results show that QW-1 with amide and quaternary ammonium groups on the molecular chain can be adsorbed onto the surface of clay particles through hydrogen bonding and electrostatic interaction to form a dense blocking layer, thus preventing further intrusion of drilling fluid into the formation.
