MANUFACTURE OF BINDER-FREE 3A ADSORBENT |
摘要 |
Shaped products of a 3A zeolite are formed either as beads or extrudates without any binder remaining. In the case of beads, a 4A powder is mixed with a caustic solution and a metakaolin clay binder to form beads. The beads are converted to a binderless 4A product which is given a partial calcium exchange followed by a potassium exchange to obtain the desired 3A binderless bead. The 3A extrudates are produced by forming binderless 4A extrudates from a 4A powder and clay mixture that contains 40-60% by weight clay. These binderless 4A extrudates are then given a potassium exchange. Both the beads and the extrudates can be used to dry a mixture of a hydrocarbon compound such as ethylene and water. |
