Abstract: Provided are a continuous crystal transformation and ion exchange device and process, belonging to the technical field of molecular sieve manufacturing. The continuous crystal transformation and ion exchange device comprises M+N reaction tanks which are in serial connection, wherein a feed opening of a latter reaction tank communicates with a discharge opening of a former reaction tank by means of a reaction solution circulation pipeline, and a discharge opening of an M+Nth reaction tank communicates with a feed opening of a first reaction tank by means of a reaction solution circulation pipeline. No more than M reaction tanks are used for a crystal transformation process, and no more than N reaction tanks are used for an ion exchange process. The method is used for preparing a finished zeolite molecular sieve product, and has the advantages of high exchange capacity, simple process, low cost and the like.

Abstract: A method of enriching nano-bentonite from a raw bentonite composition comprises the steps of mixing the raw bentonite composition with water to produce a bentonite solution, increasing the temperature of the bentonite solution to produce a warm bentonite solution, mixing the warm bentonite solution at a mixing rate to produce a colloidal solution, filtering the colloidal solution with a micro-sieve to produce a filtered colloidal solution, centrifuging the filtered colloidal solution at a centrifuge rate for a centrifuge time to produce a separated colloidal solution, wherein the nano-sized impurities are selected from the group consisting of quartz, feldspar, cristbalite, calcite, iron oxides, magnetite, calcium carbonate, and combinations of the same, and drying the separated colloidal solution to remove water to produce the nano-bentonite.

Abstract: Methods for producing mesoporous beta zeolites from parent beta zeolites having a Si/Al molar ratio of at least 10 comprise selecting a target average mesoporous size between 2 nm and 8 nm for the parent beta zeolites, selecting a pore directing agent (PDA) based on the target average mesopore size, where a non-ionic surfactant, a small cationic surfactant has a molecular weight of greater than 100 grams/mole, or both may be selected as the PDA when the target average mesopore size is at least 5 nm, and a large cationic surfactant having a molecular weight of less than 100 grams/mole may be selected as the PDA when the target average mesopore size is less than 5 nm. The method further comprises adding the selected PDA to an alkaline solution to form a PDA-base mixture, and adding the parent beta zeolites to the PDA-base mixture to produce the mesoporous beta zeolites.
