摘要： Binderless zeolite sieve extrudates are made by extruding a mixture containing about 40-60% zeolites with the remainder being a metakaolin clay that has mixed with it about 90-120% of the stoichiometric amount of sodium hydroxide to convert the clay to a zeolite. After extrusion the particles are allowed to dry age during which time most of the clay is converted to the zeolite. A further heat treatment in a dilute caustic aqueous solution insures complete crystallization with subsequent washing and calcination to produce an adsorbent product.

摘要： A method is disclosed for preparing molecular sieves of the zeolite type, particularly A, X and Y, in massive bodies that exhibit higher crush strengths than observed for prior art massive bodies. Sized unreactive kaolin-type clay, a pore generating material, and preferably a set strength enhancing agent are mixed with water to a consistency that can be shaped into preformed bodies. In the cases of zeolites X and Y silica may be included in the mixture. These bodies are calcined, optionally aged, and digested to convert them to massive bodies containing the desired zeolite.

摘要： In a process for the conversion of meta-kaolin into an aqueous alkaline suspension of low-grit, water-containing zeolitic sodium aluminosilicate of the smallest particle size having the molar composition:0.9 to 1.1 Na.sub.2 O: 1 Al.sub.2 O.sub.3 : 1.8 to 2.3 SiO.sub.2with a water content depending on the degree of drying, which contains at least 99.8% by weight of a particle size of less than 25.mu. and has a high cation exchange capability, the improvement consisting of:slowly heating a suspension of reactants to a zeolitization temperature in the range of from 70.degree. to 100.degree. C., with a temperature rise averaging 20.degree. C. within a period of from two to ten minutes,feeding the suspension, preferably before said slow heating, continuously into a reactor having progressively, separately zoned mixing areas with a stage-like effect and having at least seven stages while mixing said suspension sufficiently in the respective stages to avoid sedimentation,maintaining said suspension in the reactor at a preselected temperature in the range of from 70.degree. to 100.degree. C. until the degree of crystallization of the zeolitic sodium aluminosilicate, determined by X-ray, has reached at least 80% of the theoretically possibility crystallinity, andcontinuously removing an aqueous, alkaline suspension of zeolitic sodium aluminosilicate from the end opposite of the intake end of the reactor.The suspension traverses the reactor at a rate in the range of 1 to 3 cubic meters of suspension per cubic meter of reactor volume and per hour. Reactors preferred for the reaction are an agitator vessel cascade with at least seven vessels, an agitator column with at least seven chambers, and a flowing tube reactor which has a ratio of tube length to tube diameter in the range of 3,000 to 7,000.

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.
